Layers of the Earth- Science

Oceanic Crust and Continental Crust

the two components of the crust

Asthenosphere

upper mantle plastic/Lithosphere floats on it It allows movement to the crustic plates

Inner core

very solid

Lithosphere

It includes the crust and the upper most part of the mantle *Earthquakes, valcanos, mountain building

The crust

Top most part of the Earth solid and brittle two different types of crust Oceanic and Continental

Compositional layer

based on their chemical makeup

Mechanical Layers

based on what is actually happening in each layer

Mantle

comprises 83% of Earths volume divides into two

Lower mantle

hot/plasticy can be deformed

Outer Core

liquid

SPOTE

mantle, inner core, crust, ect.

Upper mantle

solid

The Core

the deepest layer heavy metals like iron and nickel it is divided into two, the inner and outer core
