100 POINTS: PLEASE HELP JUST FILL IN BLANKS AND MAKE GRAMMER BETTER WILL GIVE BRAINLIT, INGENUITY SCIENCE LAYERS OF EARTH PROJECT ESSAY The crust is the first layer of the Earth. This layer is the thinnest, only being 40 kilometers thick and being only 0.66% of the Earth's depth. This layer is the coolest and has the least amount of pressure. This layer contains all of the Earth’s land and oceans. It is also where all of the Earth’s life exists. Earth has two kinds of crust. These two layers are oceanic crust continental crust. Oceanic crust is composed mostly of basalt and is thinner than continental crust being 5-10 kilometers thick. Although the oceanic crust is thinner than continental crust, it is denser and younger than continental crust. Continental crust is thicker than oceanic crust is up to 70 kilometers thick. It is also composed mostly of granite. Continental crust is less dense and older than oceanic crust.

The next layer of the Earth is the lithosphere. This layer of the Earth is the second thinnest being 100 kilometers thick and making up 1.65% of the Earth’s depth. The lithosphere includes the crust and the upper part of the mantle. This layer is the second coolest being about °C. This layer's pressure is the second to least compared to the other layers. This layer is solid and is mainly composed of .

The layer after the lithosphere is the asthenosphere. This is the third thinnest layer being 180 kilometers thick and making up 2.98% of Earth’s depth. This layer is the third coolest being °C. This layer's pressure is the third to least compared to the other layers. This layer has a tarry consistency and is mainly composed of .

The next layer is the mantle. This layer is the second thickest being 2,250 kilometers thick and making up 37.21% of the Earth's depth. This layer is the third hottest being °C. This layer's pressure is the third to most compared to the other layers. This layer is solid and is mainly composed of .

The layer after the mantle is the outer core. This is the thickest layer of the Earth being 2,266 kilometers thick and making up 37.21% of the Earth’s depth. This layer is the second hottest being °C. This layer's pressure is the second to most compared to the other layers. This layer is a liquid and is made of molten . Scientists believe that the constant movement of the metal may cause the Earth’s magnetic field.

The final layer of the Earth is the inner core. This is the third thickest layer of the Earth being 1,210 kilometers thick and making up 20.01% of the Earth’s depth This layer is the hottest being °C. This layer has the most pressure compared to the other layers. This layer is solid and is made up of .
