Q

Deposition

A

Definition: The dropping of sediment that has been transported by erosion.
Factors affecting deposition: Decrease in velocity, change in the volume of water, or change in slope.

Q

what does the different erosions do?

A

Hydraulic action - water hits into rock and can compress air into cracks in rocks and break rocks.
Abrasion - rocks being carried by water and hit against rocks to break them down.
Attrition - rocks get carried by water and hit each other breaking them down and making them smother
Solution - rocks being dissolved into water

Q

what does the different Transportation do?

A

Traction: rolling or dragging of larg objects
Saltation: movement of small objects bouncing or leaping
Suspension: sedement is carried away and doesn’t touch the bottom
Solution: sedement is carried in water with out being visable

Q

what does the different Weathering do?

A

Mechanical Weathering:
the physical breakdown of rocks into smaller fragments without changing their chemical composition.
Chemical Weathering:
involves the alteration of the mineral composition of rocks through chemical reactions with agents like water, oxygen, and acids.
Biological Weathering:
Biological weathering involves the breakdown of rocks by living organisms or their activities. (plats roots)
