There are 4 layers to the Earth.
Layer #1 The Earth’s crust. The Earth’s crust is between 3 and 30 miles thick. In the Ocean, the Earth’s
crust is between 3- 6 miles thick, while on land the Earth’s crust is between 20 to 30 miles thick. We live
on the Earth’s crust. All life as we know it, also lives on the Earth’s crust. We are standing/sitting on the
Earth’s crust now. The Earth’s crust is divided into many different plates. The Earth’s plates are
represented by the black lines in the picture below. Earthquakes and geological formations like
mountains are caused by movement between these plates. When the plates run into each other it causes
mountains to form. Underneath the Earth’s crust is hot magma. Magma is lava which has not reached
the surface yet.
Layer #2 The Mantle – The earth’s mantle is underneath the Earth’s crust. The
mantle is much bigger than the Earth’s crust. The mantle is 1,800 miles thick. The
Earth’s mantle is between 5,800 degrees and 9,400 degrees Fahrenheit.
Layer #3 Liquid outer core – The liquid outer core is made up of 95 percent iron
and 5 percent nickel. The liquid outer core is 1800 miles underneath the earth’s
surface. The liquid outer core is 1,400 miles thick. The liquid outer core is between
7,232 and 10,340 degrees.
Layer #4 Solid Inner core - The earth’s solid inner core is also made of iron and
nickel. The solid inner core is around the same temperature as the surface of the sun
at 9,500 degrees Fahrenheit.
Tectonic plates – these plates are large pieces of the Earth’s crust.. There are 8 major
tectonic plates. These plates move very slowly but when they run into each other it
can create a huge crash of an earthquake or a mountain. The red arrows below show
which direction the plates are moving. If two plates are moving towards each other
it will create a mountain.
3 types of boundaries
1. Convergent boundaries – This is when two plates collide or crash into each other. This
forces one plate to go underneath another. It also causes Mountains and Volcanoes to form.
Mountains and volcanoes almost always form at plate boundaries. Convergent boundaries
are like a head on collision. (Look how the cars hoods are forced upwards)
2. Divergent Boundaries – Are when two plates are pulling apart from each other. Magma
rises from the mantle to fill the gap which is left between the two plates. This magma turns
into igneous rock when it cools off and forms part of the Earth’s crust.
3. Transform boundaries – This happens when two plates grind into each other going
opposite directions. When the two plates touch, they cause an earthquake to occur in
between them. The earthquake happens deep in the Earth at the focus, but it is seen above
ground at the epicenter. The earthquake happens at the focus and sends waves of motion
outward. We see the earthquakes movement on the surface where the epicenter is.
3 types of Rocks
1. Igneous Rock – “Born of fire” This is when magma (lava) flows up from the mantle and
becomes part of the Earth’s crust. It can rise between divergent boundaries.
Here are some pics of igneous rock.
2. Sedimentary Rock – forms when sand and small rocks are pressed together tightly.
Sedimentary rocks either look like layers, or they look like a bunch of different rocks
pressed together to looks like hard gravel. Sediment means little rocks.
3. Metamorphic Rock – forms deep down when several different types of rocks are under a
lot of pressure under the Earth. They form a new type of rock under this much pressure
called metamorphic rock. To undergo a metamorphosis means to undergo a dramatic
change. For example: caterpillars undergo a metamorphosis when they become a butterfly.
These rocks change from one type to another because of the extreme pressure. These rocks
go through a metamorphosis.
Magma and Lava
1. Lava comes from volcanoes during eruptions.
2. Magma is lava which has not reached the surface yet.
