It is consist of three major layers

core, mantle, and crust

Inner Core

about 750 miles thick and made up primarily of iron

Mantle

accounts the big volume of the earth

Mantle

covers the core and lies beneath the crust

Outermost Mantle

is cool, strong, and hard

Innermost mantle

is hot, rock is not stable, soft, plastic, and flows slowly

Crust

outermost layer

Crust

a thin veneer below a layer is soil and beneath the ocean water

Crust

composed almost entirely of solid rock

Hydrosphere

It is the liquid water component of the earth which circulates among oceans, continents, glaciers, and the atmosphere

Ocean

makes up 71% of Earth

Glaciers

cover about 10% of Earths land surface today

Atmosphere

mixture of nitrogen (78%), oxygen (21%), and other gases (1%) that surrounds Earth

Atmosphere

It supports life by regulating climate by acting as a blanket and filter, retaining heat at night and shielding us from direct solar radiation during the day
