Erosion

the removal of rock particles by wind ice or gravity

Weathering

Breaks down rock and other substances at earths surface

mudflows

rapid downhill movement of a mixture of water,rock,and soil

slump

a mass of rock and soil suddenly slips down a slope

landslides

occurs when rock and soil slide quickly down a steep slope

reep

very slow downhill movement of rock and soil

mechanical weathering is:

freezing and thawing

release of pressure

plant growth

actions of animals

abrasion 

chemical weathering includes:

actions of water

actions of oxygen

actions of carbon dioxide

actions of living organisms

actions of acid rain

abrasion

the grinding away of rock by other rock particles carried in  water,ice,or wind

Moving water

the major cause of the erosion process that has shaped earth's surface

Soil is...

mixture of rock particles,minerals,decayed organic material,water and air 

Sediment

the eroded material that is carried by water or wind

Convergent Boundary

the boundary between plates moving togeher

Divergent Boundary

the boundary between two plates moving apart

Transform Boundary

the boundary where plates slide past one another(at the same or opposite directon at different speeds)

Convection Current

the cycle of heating,rising ,cooling,and sinking of hot plastic like rock in the mantle that creates a current that moves the plates

Continental Drift

theory that the continents have drifted slowly to there current location

The evidence of continental drift

Fossil clues

Climate clues

Rock clues

plate movement

earth's crust and part of the upper mantle is broken into sections. thes sections,called plates,move on a layer of the mantle

 Hot Spots

hot spots are large rising bodies of magma that are forced through earths mantle and crust.(they don't occur on plate boundaries)
