make up the Earth to sustain life.
- Serves as the “Earth’s Blanket”
- The thin layer made up of a mixture of gases and particles suspended in the air that surround the Earth.
- A sphere that includes the solid Earth; the core, mantle, crust, and soil layers.
- Thinnest and the least dense layer of the solid earth.
- Outermost layer
40-70m thick.
The crust that makes up the continent.
Made up of less granitic rocks, sedimentary and metamorphic rocks.
6-7 km average thickness
The crust that makes up the ocean’s floor.
Made up of denser basaltic rocks.
- Thickest layer, consisting of 80% of the earth’s mass which is about 2, 900 thick.
- Semisolid and is made up of heavy rock.
- It is the densest layer of the internal layer of the Earth.
- It is about 3,500 thick from the center and has a temperature that ranges from 3, 700- 4, 300 degrees Celsius.
- Made up of heavy metals like iron + oxygen, silicon, and nickel alloy.

Composed mostly of Iron.
It is believed to have the hottest temperature at about 6, 650 degree Celsius.
- Sphere of the earth that consist of water in all forms.
- Subset of hydrosphere that consist of frozen water.
- Comes from the greek word “bios” means life.
- It is composed of all living things and the areas where they were found.
