Layers of the Earth

By Gavin Corso

INTRODUCTION Hello my name is Gavin Corso.

Today I`m going to tell you about the Layers of the Earth, going from the surface to the center. There is the Continental crust, Oceanic crust, the upper Mantle, lower Mantle, Outer core, and finally, the Inner core.

THE CRUSTSThe Continental Crust

The Continental Crust is made of Igneous, Sedimentary, and Metamorphic rocks. It is also what you and I stand on!

The Oceanic Crust This crust is under the ocean people swim in! It is made of rich iron and magnesium and is also beginning the lithosphere. Its so dense.

UPPER MANTLE• The Upper Mantle

The capacity is up to 600 kilometers! It contains magma, plates and some igneous rocks.

LOWER MANTLE

LOWER MANTLEEarths lower mantle is

made up of magnesium. It has many rocks over its 1900 kilometer stretch.

The Cores of the Earth

• Outer CoreThe outer core is

made of liquid iron and nickel. The length is a amazing 2260 kilometers!

• Inner CoreBelieve it or not

the inner core is actually made of metal and iron! Even though the temperature is nearly 9500 degrees Celsius.

CONCLUSION So there you have it! Those are

the layers of the earth. I wonder, how did you like it? It is really very interesting to know that our earth is made up of more than just dirt and plant life.
