Name: Date: 3.Sub3 Rock Cycle The Rock Cycle is a group of changes. Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock. Igneous rock forms when magma cools and makes crystals. Magma is a hot molten liquid rock made of melted minerals. The minerals can form crystals when they cool. Igneous rock can form underground, where the magma cools slowly. Or, igneous rock can form above ground, where the magma cools quickly. Period: 1. What can igneous rocks change into? (Just the words) 2. What can metamorphic rocks change into? (just the words) 3. What can sedimentary rocks turn into? (just the words) 4, How are igneous rocks formed? (Complete Sentence) Igneous rocks are formed when 5. How does magna cool underground? Magma cools ___________________ underground. 6. How does magma cool above ground? Magma cools ____________________ above ground. 7. Magma is found underneath the earth’s surface. What is magma called when magma touches the earth’s surface? Magma is called _______________________ when magma touches the earth’s surface. 8. What are sediments? (complete sentence) Sediments are When the molten liquid rock pours out on Earth's surface, magma is called lava. Yes, the same liquid rock matter that you see coming out of volcanoes. On Earth's surface, wind and water can break rock into pieces called sediments. Sediments are little pieces of rock that is broken off from larger rocks. The process of making sediments is called weathering. Weathering is the breaking of rocks into tiny rock pieces. Igneous, metamorphic and sedimentary rocks can experience weathering. Wind and water can also carry sediments to another place in a process called erosion. Erosion is when wind and water take sediments from one place to another. When erosion takes place, the wind and water drop off the sediments to make a layer. The layer can be buried under other layers of sediments. After a long time the sediments can be cemented together to make sedimentary rock. In this way, weathered and eroded igneous and metamorphic rock can become sedimentary rock. All rock can be heated. But where does the heat come from? Inside Earth there is heat from pressure (push your hands together very hard and feel the heat) and heat from friction (rub your hands together and feel the heat). So, what does the heat do to the rock? It bakes the rock. Baked rock does not melt, but it does change. It forms crystals. If it has crystals already, it forms larger crystals. Because this rock changes, it is called metamorphic. Both sedimentary rock and igneous rock can be baked to form metamorphic rocks because 9. What is weathering? (complete sentence) Weathering is 10. What types of rocks can experience weathering and become sediments? (Complete Sentence) 10. What is erosion? (Complete sentence) 11. How does erosion drop off sediments? (word) The wind and water drop off the sediments to make a __________________ 12. How is sedimentary rock created? The sediments can be _______________________ together to make sedimentary rock. 13. Where does the heat that heats up rocks come from? (complete sentence) The heat comes from 14. Instead of melting the rock, what does baking the rock do? Baking the rock does not melt, but it forms _________________ Classwork Name: Date: 3.Sub3 Rock Cycle they both will form crystals when they are heated. Igneous rocks already have crystals, so the crystals become bigger. Sedimentary rocks form small crystals and swirls. Remember that a caterpillar changes to become a butterfly. That change is called metamorphosis. Metamorphosis can occur in rock when they are heated to 300 to 700 degrees Celsius. The rock cycle never stops. Period: 15. Why are baked rocks called metamorphic rocks? (complete sentence) Baked rocks are called metamorphic rocks because 16. What type of rocks can become metamorphic rocks and why? (complete sentence) _______________________ and ____________________ can become metamorphic rock because 17. What happens to igneous rocks when they are heated? (CS) When igneous rocks are heated, their crystals 18. What happens to sedimentary rocks when they are heated? (complete sentence) When sedimentary rocks are heated, sedimentary rocks form Match the type of rock with how it is formed: _______ 19. Igneous A. Changes by forming or making bigger crystals due to heat and pressure _______ 20. Sedimentary B. Forms when magma (lava) cools and makes crystals _______ 21. Metamorphic C. Forms when sediments become cemented together 22. Weathering is when: A. Something solidifies into a rock B. Rocks are broken down into small sediments C. A rock turns into a mineral D. The sun bakes a rock 23. If Sedimentary rock undergoes enough heat and pressure to form crystals, which type of rock will it change into? A. Sedimentary B. Igneous C. Metamorphic D.
