Weathering
How are weathering and erosion connected?
Weathering breaks down rocks and erosion moves the broken pieces
What is erosion
Erosion is the movement of material
What is Erosion?
the process of eroding by wind, water, ice, or even gravitational pull.
What comes first, weathering or erosion?
Weathering
Describe how a glacier can carve through rock
As the glacier melts, it starts to move and pick up rocks. The rocks grind against the land
What happens after a rock is weathered?
The rock is broken down rock is moved to another location
Which of the following are erosion processes? A.Gravity erosion- Movement down a lope due of gravity. B.Water erosion- Erosion caused by either raindrops or heavy rain. C. Shoreline erosion- Occurs due to the action of currents and waves. D. Wind erosion- Movement of material by the wind.
A. B. C. D.
What direction does erosion move earth materials?
Downward with gravity, across with wind or water
Describe the process of erosion
Various Answers relating to sediments or broken rock particles being moved by any of the agents of erosion.
Erosion can be caused by what kind of weathering? Hint: physical, chemical, or all.
All types of weathering
What is deposition?
Deposition is when particles are carried by water, wind, ice, and deposited into a new location.
On lakeshore drive one may notice the cement wall of steps that are between the road and the ocean. What is the purpose of this seawall?
The purpose of this seawall is to absorb the pounding waves and protect from erosion
What happens after weathering and erosion?
Deposition
While driving along the highway 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?

Give an example of how weathering could be destructive.
Weathering can damage structures and during e violent storms, such as a hurricane, or flood. These events or occurrences may have long lasting effects.
How could erosion be prevented?
Anything that can stop dirt or rocks from moving, various answers depending on erosional type.
As humans why is it important to understand weathering and erosion?
It is important to understand weathering and erosion, so that we can prevent or better prepare for weathering to keep material from breaking down
Describe why rocks found at the bottom of a river are smooth and flat
They have been weathered by moving water
