2.  My class will be studying the earth, and so the subject is Geology.  We live in the Biosphere.  That glacier is considered to be part of the Hydrosphere.  We breath the mixture of air from the Atmosphere.  I am standing on the Lithosphere.

3. 6.The earth’s crust can be compared to an egg shell. 7.The mantle would be the egg white in a boiled egg.

4. 1.Geology: The study of the solid Earth. 2.Biosphere: All living things. One of the four spheres into which scientists divide earth. 3.Hydrosphere: Earth’s water and ice. One of the four spheres into which scientists divide earth. 4.Atmosphere: The mixture of gases that surrounds Earth. One of the four spheres into which scientists divide earth.

5. 5. Lithosphere: A solid layer made up of the uppermost part of the mantle and the crust. One of the four spheres into which scientists divide earth. 6.Crust: The layer of rock that forms Earth’s outer surface. 7.Mantle: The layer of hot solid material between Earth’s crust and core.

6. 8. Asthenosphere: The soft layer of the mantle on which the listhosphere floats. 9.Outer Core: A molten sphere of nickel and iron surrounding the solid inner core. 10.Inner Core: A dense sphere of solid iron and nickel in the center of the Earth.
