Lithosphere Unit

Hard, rocky portion of Earth.

• Hydrosphere
• Lithosphere
• Atmosphere
• Meterology

The middle portion of the mantle...
Plates float on top of it

• Asthenosphere
• Lithosphere
• Erosion
• Ocean

Boundary between crust and upper mantle

• Blue Boundary
• Atmosphere
• Moho Boundary
• Lithosphere

Outermost layer
Thinnest layer
Made mostly of silica, oxygen, and aluminum

• Core
• Crust
• Lava
• Region

Between the crust and core •Divided into two layers: Upper and Lower
Thickest layer containing most of Earth’s mass
More dense than crust Contains more magnesium and less silicon and aluminum than the crust

• Mantle
• Crust
• Layers
• Magnesium

Below the mantle and is the center of Earth
Mostly iron and some nickel, almost no silicon, oxygen, or aluminum
2 layers: –Outer (liquid) –Inner (solid)
-Responsible for Earth's magnetic field

• Magma
• Crust
• Core
• Trees

•Solid •Naturally occurring •Made of minerals •No definite chemical composition •Preserve Earth’s history when they are formed

• Rocks
• Mountains
• Crust
• Clouds

•A rock formed from cooled magma or lava (“fire”)

• Igneous
• sedimentary

•the breakdown of rock 

• Weathering
• Building
• Magnesium
• change

–the breakdown of rock by wind, water, ice, gravity, etc…, does not change the composition of the rock

• Physical Weathering
• Chemical Weathering
