What types of changes are included in the process of weathering? A. Chemical changes B. Physical changes C. Both
C. Both
100
Is erosion a natural process?
ExplainYes. Erosion is as natural as weathering is natural. Because of the 4 earth spheres.
100
What is Erosion?
the process of eroding by wind, water, ice, or even gravitational pull.
100
What comes first, weathering or erosion?
Weathering
100
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, sediment, rocks

200
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 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 (with gravity) 

200
Are erosion and weather dependent on one another? Explain
Yes- They both need to occur for the cycle to continue.

What eroded away the rocks that created the Grand Canyon? 

water (from the Colorado River) 

300
Erosion can be caused by what kind of weathering? Must be able to name at least 3
1. Wind 2. Ice 3. Water 4. Gravitational pull

What is an example of mechanical weathering? 

Bryce Canyon

St. George's Head

waves on a cliff

wind on a rock

On Lakeshore Drive in Chicago, 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 pounding waves and protect the coast behind it. Protect the road and buildings beyond from erosion.

What pulls pieces of rock downhill to create a landslide?
Gravity

When my grandmother's house was built I remember the paint on the porch was white. Now it has chipped. What is this caused by?

Weathering

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

What is an example of chemical weathering? 

Statue of Liberty turning green

Red soil from oxidation + other answers possible

A sloping restaurant on the grass puts a cement wall along the side of the building with large boulders. Why? A. To improve the view B. To keep the building from rolling C. They keep the soil in place D. They look nice
C

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.

Breakdown structures making them unsafe, change the shape of buildings, statues, and landforms

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. How might you fix this? Make a hypothesis.

Answers may vary: ex - 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.
500
How might erosion negatively affect plants?

Erosion can carry the soils away and plants need soil to hold it in place and provide nutrients. 

500
What is deposition?
Deposition is when particles are carried by water, wind, ice, and deposited into a new location.
