earth's structure
TRANSCRIPT
Compositional Zones
0Crust: outermost layer0Makes up 1% of Earth’s mass0Oceanic (5-10km) & continental
(15-80km)0Moho: lowest layer of crust
Compositional Zone
0Mantle: denser than crust02,900 km thick (2/3 of Earth’s
mass)0Core: center of the Earth0Made of iron and nickel
Structural Zones
03 compositional zones are divided into 5 structural zones.
0Lithosphere: Part of the mantle & crust above it.0Cool & brittle
0Asthenosphere: Solid rock is able to flow. 0Very hot and has high pressure
0Mesosphere: Layer of solid mantle rock0Outer core (liquid)0Inner core (solid)
