things, air; but in scientific language, we call
them differently.

3. Lithosphere
• Lithosphere-Land, earth that we are living on;
also we can call undergrounds as a
lithosphere.

4. Hydrosphere
• Hydrosphere-water that we all need, and
cannot survive without it. Ex: Oceans, lakes,
rivers, etc.

5. Atmosphere
• Air that we are all breathing; also, known as
oxygen.

6. Biosphere

• For example: Plants, trees, animals, humans,
etc; everything that absorbs oxygen.

7. Layers of Earth
• Earth is made up of bunch of different layers;
but there’s four most significant layers, they
are: Oceanic Crust, Continental Crust,
Asthenosphere, Mantle, Outer & Inner Core.
Each layer of earth has it’s specific job, and
characteristics.

8. Inside-to-outside
• Inner, outer, lower, upper, crust.

9. Oceanic Crust
• Oceanic Crust-is much thinner than
Continental; under the sea, like islands, lands
under the sea.

10. Continental Crust
• Continental Crust- made up of minerals and
rocks.

11. Asthenosphere
• Asthenosphere-Upper mantle, it’s a solid rock,
which can flood like a liquid.

12. Mantle
• Mantle-Layer of the beneath the crust, made
up of a rock that flows slowly.

13. Outer Core
• Outer Core-is a liquid. The outer core is 2300
km thick. Outer Core composed of nickels and
irony.

14. Inner Core
• Inner Core-is a solid, it is 1200 km thick, it is
composed of iron.
