what determines the rate of weathering |
type of rock, permeable, climate, human activities |
|
|
erosion |
removal of rock particles by wind, water, ice or gravity |
|
|
how do weathering and erosion work together |
weathering breaks up the rock and erosion moves it away; "video said weathering causes the mess, and erosion cleans up the mess" |
|
|
physical/mechanical weathering |
the break down of rocks and minerals; disintegration or breaking of rock material into small fragments or pieces;chemical components of rock remain unchanged |
|
|
chemical weathering |
process that breaks down rock through chemical changes |
|
|
weathering |
process that breaks down rocks and other substances at earths surface.; slow process |
|
|
Agents of mechanical/physical weathering |
ice, wind, gravity, plants, animals |
|
|
agents of chemical weathering |
water, oxygen, carbon dioxide, living organisms, acid rain |
|
|
agents of erosion |
gravity, running water, glaciers, waves, wind |
|
|
sediment |
material moved by erosion |
|
|
deposition |
occurs where the agents of erosion lay down sediment |
|
|

force that moves rock and other materials downhill |
|
|
types of gravity |
