EARTH’S SUBSYSTEMS

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.

Only layer of the earth that is liquid.

Located below the mantle and is about 1,400 miles thick.

The molted (liquid) metal is about 4, 700 degree Celsius (8, 500 degree F).

It is composed of the melted metals nickel and iron.

Solid center of the planet.

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.
