Is weathering a slow change or fast change?
slow change
Is erosion a natural process?
Yes. Erosion is as natural because it is not caused by man.
The movement of soil or sediment from one location to another by way of water, ice, or wind
Erosion
How do the processes affect the earth overall?

sediment
Which of the following is NOT an erosion processes?
A. Rocks broken down by crashing into other rocks.
B.Sand along a shore carried away by waves.
C. Small pebbles moved to a curve in the river.
D. Sand carried by wind in the desert.
A.Rocks broken down by crashing into other rocks is an example of weathering.
The breaking down of substances such as rocks or minerals by physical, chemical, or biological processes.
Weathering
How would other earth materials, such as rocks or trees, impact erosion?
The change the path of erosion/ slow it down
Can erosion happen before weathering?
No, weathering must occur first, then the broken pieces are carried away.

B. Deposition
C. Weathering
Deposition
What pulls pieces of rock downhill to create a landslide?
Gravity, often loosened by water

While driving along the highway, I noticed huge rocks along the road. 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
Can erosion be stopped?
no, but it can be slowed down
Water getting into cracks, freezing, and breaking the rocks or pavement apart is an example of _____.
A. Erosion
B. Deposition
C. Weathering
Weathering
How does the slant of land affect erosion?
The more slant there is, the more erosion can occur
Weathering can't break down the Earth's crust.
False
Caves being formed by acid rain dissolving underground limestone is an example of erosion.
False
When particles carried by wind, water, or ice are dropped in another location.
Deposition
How do we use the knowledge we have of weathering and erosion to help us know how to build our homes?
Build our homes on a strong foundation away from commonly eroded areas (side/base of mountain, on sand, etc.)
What is deposition?
Deposition is when particles are carried by water, wind, ice, and deposited into a new location.
