35-40km Thick. Rock type ranges from mafic to felsic.
Continental on average less mafic (felsic to
Continental Crust:
intermediate composition) than oceanic, furthermore
less dense. Oxygen = most abundant
2885 Km thick layer - largest part of earth. Consists
entirely of ultramafic (dark and dense) rock called
Mantle peridotite, making peridotite most abundant rock on
planet. Almost all mantle is solid rock but its soft
enough that it flows
Outer core: liquid iron alloy, this flow of iron alloy
Outer/Inner Core: creates magnetic field
Inner core: solid iron because of pressure
Pressure and temperature both increase with depth in
Gradients in Earth: the Earth. The rate at which temperature increases as
depth increases is the geothermal gradient.
Interior: 80% of energy from decay of radioactive
Sources of energy for the
elements
earth
Exterior: Sun
Exterior Processes (Fast): Wind, weather, rivers, currents, glaciers
plate tectonics.. mountain building, earthquakes,
Interior (Slow):
landslides, volcanoes, oceans open/close...
