Is erosion a natural process?
ExplainYes. Erosion is as natural as weathering is natural. Because of the 4 earth spheres.

What is Erosion?
the process of eroding by wind, water, ice, or even gravitational pull.

What comes first, weathering or erosion?
Weathering

Do humans have anything to do with weathering and or erosion? Explain
Yes, depending on how we take care of earth, earth will take care of us. Many storms occur based on how we take care of the water and air on earth.

After weathering occurs, what is left over from the rocks that have been broken down? Must name at least 2 things
dirt soil

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.

All of Them (ABCD)

What is weathering?
Weathering is the process of breaking down and weakening sediments that will be moved by erosion.
200
What direction does erosion move earth materials?
Downward
200
Are erosion and weather dependent on one another? Explain
Yes- They both need to occur for the cycle to continue.

On lakeshore drive one may notice the cement wall of steps that are between the road and lake Michigan. What is the purpose of this seawall?
The purpose of this seawall is to absorb the pouding waves and protect the coast behind it.

What is the difference between weathering and erosion?
Weathering is the process of breaking parts of the earth down Erosion Gets rid of the elements of the earth that have moved and are left behind.

Give an example of how weathering could be destructive.
Weathering may include violent storms, such as a hurricane, or flood. These events or occurences may have long lasting effects.

Your school park was built on gravel. Your school park has closed because erosion has been happening. The swing set has begun to move forward and sunk into the ground. The school has asked your science class to come up with a plan to solve the problem. Write a hypothesis for an experiment you could conduct.
If my science class replaced the gravel in the park with soil and grass the swing set will stay in place and slow erosion down.
500
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 as well as make observations to compare to something we have seen before.

Why do plants need soil?
Holds plants in place.

What is deposition?
Deposition is when particles are carried by water, wind, ice, and deposited into a new location.
