Weathering
What are 2 types of weathering?
chemical and physical weathering
What is erosion?
Erosion is the carrying away or moving rocks and sediment to a new location
When does erosion happen in the cycle?
A. before weathering B. after weathering
C. after deposition
b. after weathering
What is deposition?
When rocks and sediment are dropped or deposited in a new place.
iron combines with oxygen to make rust - What kind of chemical weathering (Oxidation, Hydrolysis, Carbonation)?
Oxidation
what is an example of physical weathering?
Weathering from water, wind, ice, or living things.
What is an example of wind erosion
Wind blowing sand from a sand dune to another location
What is weathering?
Weathering is the process of breaking down and weakening sediments that will be moved by erosion.
When does deposition happen in the cycle?
A. Before weathering or
B. After erosion
B
What is ice wedging?
Water freezes in rocks, expands and pushes the rocks further apart
What is an example of chemical weathering?
acid rain, oxidation, hydrolysis, carbonation
Erosion can be caused by what 3 kinds of weathering?
1. Wind 2. Ice 3. Water
Give and example of water erosion
An example of water erosion is when a river pulls sediment and small rocks from the riverbanks and carries it all down stream to another place.
What pulls pieces of rock or sediment down to a new location on the earth.
Gravity
What process leads to deltas, sandbars and dunes?
Deposition
What is the correct order of the 3 parts of the erosion cycle? (Deposition, weathering, erosion)
weathering, erosion, deposition
Name two things that effect the rate of erosion from rivers
Age of a river,
Slope
Speed of river
Surrounding environment
What is an example of ice erosion
An example is when a glacier scrapes rock and sediment as it moves down hill, and leaves it in a different location
What is the difference between deposition and erosion?
Erosion takes broken rock and sediment and moves it to a different place.
Deposition is the dropping or depositing of the rock and sediment in the place.
any form of water that falls from the atmosphere to Earth's surface, such as rain, snow, sleet, or hail:

Precipitation
Give an example of how weathering could be destructive.
Weathering may include violent storms, such as a hurricane, or flood.
Rocks, mudslide, or snow can collect and slide down the side of a mountain
A town planted grass and trees around a hill. What part of the erosion cycle were they trying to stop: erosion or deposition?
erosion
the natural features of land, esp. the shape of its surface, or the science of mapping those features: is called: T_ _ o _ _ _ _ y
