Weathering
What is it called when wind weathers rock down?
Abrasion
The Grand Canyon is an example of erosion by what?
Erosion by water.
Name a landform that is caused by wind erosion/deposition.
Dunes, sculpted rock
What is the a source of deposition?
Water, wind, ice, gravity
A large chunk of ice moving across the land is called a what?
Glacier
What is an example chemical weathering?
Acid rain, rust, chemical dissolving (like limestone caves)
Name a landform that is caused by glaciers.
Glacial striations, moraines,
Name a landform that is caused mainly by deposition.
Delta, Floodplain, beaches, moraines
Where on a stream bend will more erosion occur?
the outside of the bend
What type of rock can be dissolved by acid rain and commonly forms caves
Limestone
What is it called when a river winds more and more due to erosion and deposition?
Meander
What 3 processes create landforms?
Weathering, erosion, deposition
What does a glacier deposit? (the mix of rocks are called this)
Till
This type of erosion took place recently in Nepal and created a massive flash flood
Mass Movement (Landslide)
This type of weathering occurs when water freezes and thaws several times, breaking rocks apart.
What is ice wedging?
What is an example of erosion by gravity?
Rockslides/ landslides
Very small bits of soil and rock that make up landforms are called what?
sediment
Beaches are formed by this agent of deposition.
Water
The water that comes off of glaciers is called this
Outwash
This type of weathering is caused by plants growing between rocks and splitting them apart.
What is root wedging?
What are two factors that can change the rate of stream erosion?
Load, Gradient, Discharge
