Weathering
What are 2 types o 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.
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 an example of chemical weathering?
acid rain
Erosion can be caused by what 3 kinds of weathering?
1. Wind 2. Ice 3. Water
Why can't the cycle of weathering, erosion, and deposition be stopped?
The erosion cycle is part of nature. Humans can't stop it, but we can help slow it down.
What pulls pieces of rock or sediment down to a new location on the earth.
Gravity
What is the correct order of the 3 parts of the erosion cycle?
weathering, erosion, deposition
While driving along the highway in Pennsylvania I noticed huge rocks along the highway. Large nets covered these rocks and seemed to go from the top to the bottom. Were these nets put in place to stop weathering or erosion?
erosion: even when rocks become broken they can not be carried or moved to another location
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 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.
Give an example of how weathering could be destructive.
Weathering may include violent storms, such as a hurricane, or flood.
Rocks, mud, or snow can collect and slide down the side of a mountain
Why is it important for us to learn about how weathering and erosion happen
Then we can help prevent erosion by planting on hills and on the banks of rivers
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
A town planted grass and trees around a hill. What part of the erosion cycle were they trying to stop: erosion or deposition?
erosion
