Rock Cycle

Located ABove parent material

moved away from parent bedrock

vertical sequence of of soil layers

• Naturally Occuring
• Inorganic Solid
• Definate Crystalline Structure
• Specific Chemical Composition

A solid in which the atoms are arranged in a repeating pattern.

molten material found beneath earths crust

Color, Luster, Streak, Cleavage & Fracture, Hardness, Density & Specific Gravity, And Texture

Oxygen

silicates

crystallization of magma

• intrusive- coarse grained rocks. cooled slowly underneath earths crust.
• extrusive- Fine grained rocks. cooled quickly on earths surface.

pieces of solid material that have been deposited

deposition burial & lithification

heat & pressuree!

• mechanical- physical
• chemical- composition

stripping away outter layers

water inside cracks, cold, freezes, ice expands, rocks crack even more

water oxygen carbon dioxide acids

• the reaction of substances with water.
• the reaction of substances with oxygen.

final stage of erosion process

the most signifigant cause of erosian

w/o gravity, glaciers would not slope downward

carries sediments

moves particles

loose covering of broken rock particles and organic matter

texture fertility color

little distinction

• polar soils- high altitudes
• temprate soils- support a diverse enviroment
• desert soils- high level of accumulated salt
• tropical soils- weathered and infertile

how well a soil can support a growth of plants.
