The top layer of the Earth is the crust made of mostly soil and rocks. Smaller rocks come from the breakage and weathering of larger rocks. Second layer is the mantle; made of hot rocks and metals. Geologists believe the core is made of a solid ball of metal. But, the important thing about the Earth is it is made of materials that have distinct properties and provide resources for human activities. Page 2 The important thing about the Earth is it is made of materials that have distinct properties and provide resources for human activities. Sedimentary rocks have many layers They are formed under lakes and oceans. They are made by small pieces of plants, rock and dead animal fossils over thousands of years. Scientists learn about the past history of Earth by studying fossils. Sandstone and limestone are examples of sedimentary rocks. But, the important thing about the Earth is it is made of materials that have distinct properties and provide resources for human activities. Page 3 The important thing about the Earth is it is made of materials that have distinct properties and provide resources for human activities. The word metamorphic means “change”. Heat, time, and pressure of magma rock layers change rocks into metamorphic rocks. Both igneous and sedimentary rocks can become metamorphic rocks. Granite rock changes to gneiss, shale into slate, and sandstone into quartzite. 12 But, the important thing about the Earth is it is made of materials that have distinct properties and provide resources for human activities. Page 4 The important thing about the Earth is it is made of materials that have distinct properties and provide resources for human activities. Igneous rocks are made from melted rocks called magma. Sometimes magma squeezes up between the layers of rock, harden, and forms underground. When magma comes to the surface it is called lava. Pumice and obsidian are examples of igneous rocks. But, the important thing about the Earth is it is made of materials that have distinct properties and provide resources for human activities. Page 5 The important thing about the Earth is it is made of materials that have distinct properties and provide resources for human activities. When magma erupts from a volcano, it is called lava. During an eruption, lava, rocks, dirt and ash shoot into the air. Obsidian is a rock that forms when magma cools and hardens. Native Americans used obsidian to make arrowheads and tools. But, the important thing about the Earth is it is made of materials that have distinct properties and provide resources for human activities. Page 6 The important thing about the Earth is it is made of materials that have distinct properties and provide resources for human activities. Rocks are made from different physical properties and are composed of minerals. Soil is made partly from weathered rock and partly from organic materials. Soils differ in their color, texture, capacity to retain water, and ability to support the growth of many kinds of plants. 13 Rocks, water, plants, and soil found on Earth, provide many resources including food, fuel, and building materials, that humans use. But, the important thing about the Earth is it is made of materials that have distinct properties and provide resources for human activities. 14 Geology Rocks Big Book Page 1 Studying rocks is geology, and rocks are an important part of our universe. The planet Earth is a sphere made almost entirely of rock. It measures 25 thousand miles around and weighs 6.6 sextillion tons. Though our planet appears to be mostly water, it is only on the surface. Underneath those first few miles of ocean lie 8 thousand miles of rock! Since understanding the universe is pretty important, we think geology rocks! Page 2 Studying rocks is geology, and rocks are an important part of our universe. The landforms of the Earth's geography, such as mountains and hills, have been created by the movement of plates of rock about 50 miles thick. When these plates bump against each other, pressure builds up, and can cause earthquakes or volcanoes. Earthquakes can push rock from the interior of the earth up above the surface, and volcanoes throw off molten rock which can cover the surfaced, creating new land forms. Since understanding the universe is pretty important, we think geology rocks! Page 3 Studying rocks is geology, and rocks are an important part of our universe. All rocks can be classified into three different types: igneous, sedimentary, or metamorphic. Igneous comes from the Latin word meaning “fire”. Sedimentary means “settling to the bottom” of small pieces of material. Metamorphic comes from Greek, meaning “to change form”. Since understanding the universe is pretty important, we think geology rocks! Page 4 Studying rocks is geology, and rocks are an important part of the universe. Igneous rock is liquid magma from volcanoes turned solid. When magma cools quickly, it hardens into sharp, shiny rocks like obsidian, perfect for making tools. When it cools slowly, bumpy rocks made up of large particles, like 15 granite, are formed. Chunks of magma cooling beneath the Earth's surface are called plutons, and when water is nearby, a geyser may be formed. Since understanding the universe is pretty important, we think geology rocks! Page 5 Studying rocks is geology, and rocks are an important part of our universe. Sedimentary rock is the most common of the three rock types. Sand or tiny particles of sea creatures settle to the bottom of a river or ocean and they get squeezed together as the layers of sediment get heavier. The rock formed may then be pushed to the surface by plate movement, or may be left exposed when the water evaporates. One type of sedimentary rock, limestone, was used to build the Egyptian pyramids. Since understanding the universe is pretty important, we think geology rocks! Page 6 Studying rocks is geology, and rocks are an important part of our universe. Metamorphic rock used to be igneous or sedimentary, but has been changed by heat or pressure. When rock is covered by magma, or pressed together by the constant rubbing of Earth's plates, it goes through chemical changes. The marble from which statues are carved, and the slate from which blackboards were made are examples of metamorphic rock. Since understanding the universe is pretty important, we think geology rocks! Page 7 Studying rocks is geology, and rocks are an important part of our universe. Weather also cause many changes in rocks through a process called erosion. Wind and water can carve away at rock, creating some of nature's most spectacular sights. Erosion can also turn a spectacular mountain into a tiny hill. Over many centuries, erosion grinds down solid rock into tiny particles of dirt. Without this nutrient-rich soil, plants could not grow and there would be very little life on Earth. Since understanding the universe is pretty important, we think geology rocks! 16 Page 8 Studying rocks is geology, and rocks are an important part of our universe. Rock makes it possible to do so many different things that it is hard to imagine life without it. Rock is used in the construction of roads and buildings. Precious stones, or gems, are used for jewelry and for tool parts. Mineral ore extracted from rock provides metal and other minerals are used in medicines. Many people enjoy collecting rocks just for the fun of it! Since understanding the universe is pretty important, we think geology rocks! Page 9 Studying rocks is geology, and rocks are an important part of our universe. Scientists have learned much about life on this planet millions of years ago by studying fossils of plants and animals which have turned to rock. They are investigating whether life exists on other planets by studying rocks brought back during space explorations. When the Earth is hit by masses of rock a few miles across, call asteroids, or by meteoroids, which are smaller chunks of metal and rock, we get even more information about our solar system. Since understanding the universe is pretty important, we think geology rocks! 17 Name _________________________________ 18 Rocks Here, Rocks There By Noshaba Afzal Rocks here, rocks there Rocks, rocks everywhere!

There are three different ways that rocks are formed, Listen up and you’ll be informed. Igneous is the first you should know, It’s formed by magma when it’s cooled down below. Granite and basalt are a couple of names, Obsidian is glassy and pumice floats away! The next kind of rock is Sedimentary, You can tell be the layers it carries. Limestone and sandston to name a few, Coal, shale, and conglomerate, too! Now we come to the final one, It’s called Metamorphic – the changing one. Some rocks changing into one name schist, Now listen to the others so they don’t get missed! Limestone to marble, granite to gneiss, Shale to slate, and quartz to quartzite! You’ve heard the three, now name them all: Igneous! Sedimentary! Metamorphic! Now you know the Rocking Rap, And that’s a fact! 22 Rock Science Bugaloo By Laura Curry and Tessa Williams We’re rock scientists and we’re here to say, We study earth’s secrets everyday.

Rushmore was carved from it Everybody Needs A Rock By Byrd Baylor 1 Everybody needs a rock. I’m sorry for kids who don’t have a rock for a friend. I’m sorry for kids who only have tricycles, bicycles, horses, elephants, goldfish, three-room playhouses, fire engines, wind-up dragons, and things like that—if they don’t have a rock for a friend. That’s why I’m giving my own TEN RULES for finding a rock…Not just any rock. I mean a special rock that you find yourself and keep as long as you can—maybe forever. 2 If somebody says, “What’s so special about that rock?” don’t even tell them. I don’t. Nobody is supposed to know what’s special about another person’s rock. All right. Here are the rules: RULE NUMBER 1: If you can, go to a mountain made out of nothing buy a hundred million small shiny beautiful roundish rocks. But if you can’t, anyplace will do. Even an alley. Even a sandy road. 3 RULE NUMBER 2: When you are looking at rocks don’t let mothers or fathers or sisters or brother or even best friends talk to you. You should choose a rock when everything is quiet. Don’t let dogs bark at you or bees buzz at you. But if they do, DON’T WORRY. (The worst thing you can do is go rock hunting when you are worried.) 27 4 RULE NUMBER 3 Bend over. More. Even more. You may have to sit on the ground with your head almost touching the earth. You have to look a rock right in the eye. Otherwise, don’t blame me if you can’t find a good one. 5 RULE NUMBER 4 Don’t get a rock that is too big. You’ll always be sorry. It won’t fit your hand right and it won’t fit your pocket. A rock as big as an apple is too big. A rock as big as a horse it MUCH too big. 6 RULE NUMBER 5 Don’t choose a rock that is too small. It will only be easy to lose or a mouse might eat it, thinking that it is a seed. (Believe me,that happened to a boy in the state of Arizona.) 7 RULE NUMBER 6 The size must be perfect. It has to feel easy in your hand when you close your fingers over it. It has to feel jumpy in your pocket when you run. Some people touch a rock a thousand times a day. There aren’t many things that feel as good as a rock—if the rock is perfect. 8 RULE NUMBER 7 Look for the perfect color. That could be a sort of pinkish gray with bits of silvery shine on it. Some rocks that look brown are really other colors, but you only see them when you squint and when the sun is right. Another way to see colors is to dip your rock in a clear mountain stream—if one is passing by. 28 9 RULE NUMBER 8 The shape of the rock is up to you. (There is a girl in Alaska who only likes flat rocks. Don’t ask me why. I like them lumpy.) The thing to remember about shapes is this: Any rock looks good with a hundred other rocks around it on a hill. But if your rock is going to be special if should look good by itself in the bathtub. 10 RULE NUMBER 9 Always sniff a rock. Rocks have their own smells. Some kids can tell by sniffing whether a rock came from the middle of the earth or from an ocean or from a mountain where wind and sun touched it every day for a million years. You’ll find out that grown-ups can’t tell these things. Too bad for them. They just can’t smell as wells as kids can. 11 RULE NUMBER 10 Don’t ask anybody to help you choose. I’ve seen a lizard pick one rock out of a desert full of rocks and go sit there alone. I’ve seen a snail pass up twenty rocks and spend all day getting to the one it wanted. You have to make up your own mind. You’ll know. 12 All right, that’s ten rules. If you think of any more write them down yourself. I’m going out to play a game that takes just me and one rock to play. I happen to have a rock here in my hand… Blue text—speech bubbles 29 Name __________________________________________________ HOME/SCHOOL CONNECTION #1 Retell Byrd Baylor’s book, Everybody Needs a Rock, that you heard in class today to your parents.

Recycle old and change some of these old around for more being changed into rocks are constantly being means to take something into something new. So rocks that have been than four billion years are different rocks. Of course, that doesn't happen over night. It takes millions of years. To better understand how this happens, let's take a journey through the rock cycle. First, our journey begins in the mantle. Here we see some red hot magma that is being pushed up towards the crust. Some of this magma creeps into the cracks of the volcano; while, the rest is forced out of the top of the volcano. Once the magma is out of the volcano, it is called lava. The lava cools and forms igneous rocks. Then some of the igneous rocks roll down the mountains formed by the volcanoes and eventually end up in the ocean. As they roll, bits and pieces of the igneous rocks are broken and form sediments. Layer after layer of sediments are pressed and cemented together forming sedimentary rocks. Some of the sedimentary rocks on the very bottom get hot because of the pressure and change to metamorphic rock. When the metamorphic rock is buried deeper, it gets hotter and melts. Once again, it becomes magma and may eventually be pushed up and out of a volcano. The rock cycle begins all over again!

Rocks can change their form when they turn into new rocks called metamorphic rocks. Most rocks are very hard, so it takes a lot of heat, pressure, and time for a rock to change into a new rock. Characterisitics Marble comes in many colors and shades such as blue, green, pink, purple and white. Marble usually has darker colored bands or lines and is embedded with quartzite. How It Is Used Marble is very beautiful when polished. It is used for tiles, monuments, tables and decorations of all types. 42 Facts We Think Are Interesting Limestone is a bumpy sedimentary rock with visible fossils or shells. When it is put under tremendous heat and pressure, over time it becomes a new rock called marble. 43 Expert Group #2 Sandstone Type of Rock/How It is Formed Sandstone is a sedimentary rock. It is formed when sediments are carried by rushing water settling gently at the bottom of rivers, lakes, and oceans. These sediments of dead animals and plant life form thick layers over many, many years. Under heavy weight and extreme pressure of the many layers above, the bottoms layers fuse together and form sedimentary rocks. Characteristics Sandstone is formed from layers of sand that have been pressed together by extreme pressure. Sandstone feels gritty. It is not a very hard rock and breaks apart easily. How It Is Used Sandstone is often used to decorate gardens. Sandstone is also broken down to make cement compounds. 44 Facts We Think Are Interesting Often in the layers of sandstone there are imprints of dead plants and animals pressed in. Sandstone can also bend and twist like wire. How cool is that! 45 Expert Group #3 Petrified Wood Type of Rock/How It Is Formed Over 225 million years ago a large basin area with lush landscape, various flora, and many rivers and streams flowed through the lowlands. Arizona, New Mexico, and Utah were located near the equator and the environment was more tropical and humid. Over time trees died and the rivers carried the trees into the lowlands. The trees were buried in layers of mud, sand, or volcanic ash. Then water seeped through the layers. Characteristics Minerals in the water took place of the wood. The trees became solid stone, but their shape remained the same. That is why the petrified wood looks like real wood. The color of the petrified wood reveals the minerals that were involved in creating a rainbow of colors, or lack of, within the petrified material. How It Is Used Petrified wood has many uses. It is used to make furniture, tables, home and garden decorations. It is also worn by women as jewelry. Expert Group #4 Geodes 46 Facts We Think Are Interesting Petrified wood comes from the word petrify, which literally means “turn to stone.” Petrified wood is not only rare and beautiful objects, but also filled with remarkable history, which makes it very interesting fossil. 47 Expert Group #4 Geodes Type of Rock/How It Is Formed A geode is a very unusual rock. When this type of rock formed over many, many years, liquids and gases were trapped inside and formed special shapes called crystals. Geologists do not classify geodes under any of the three types of rocks because none of their definitions fit. Characteristics When a geode is split open, a hollow center partly filled with beautiful mineral crystals can be seen. These crystals come in all colors and are sometimes multicolored. The outer side of a geode is plain grey in color. It is usually round or oval in shape. How It Is Used Geodes are found in many parts of the world. They are mainly used for decoration pieces and jewelry. 48 Facts We Think Are Interesting Depending on the size, shape, and color of the crystals, geodes can be very expensive. Many people are willing to pay the expense as geodes are very unusual and unique. 49 Expert Group Mind Map Type of Rock/How Formed Characteristics Rock: How it is used Interesting Facts 50 A B G C D E F H I J K L M N O P Q R S T U V W X Y Z THE ABC’s OF ROCKS 51 Graphic Organizer: Weather and Erosion weathering: causes rocks to crack, crumble, fragment, or break down three main causes 1. ice—“freeze and crack Water gets in the cracks of rocks Water freezes and expands and forces the rocks to split 2. plants—“roots of destruction” Plants grow in the cracks of rocks Roots force the rocks to crack 3. chemical changes— “chemical destruction” Chemicals in the air break down rocks Example: iron meets oxygen=rust Is weathering good? YES! Why? 1. This is how soil is made. 2. We get products from weathering, like aluminum. Erosion: loosens and carries away rocks and debris caused by weathering 1. wind 2. ice—glaciers 3. water—rain, waves, running water 52 53
