After a heavy rain, you notice soil from your flower beds has washed into the street. Explain what happened and why it happened.
WEATHERING happens when the water lifts the soil from the flower bed. EROSION happens when the soil is carried to the street. This happened because a large amount of water caused land to change by moving it around.
200
The GRADUAL wearing down by wind, water, air and natural events.
Erosion

How fast the process by which water, ice, wind, and gravity transport sediments from one place to another is called the ________________
rate of erosion

What environment do you think will become eroded faster- a beach with tall grasses and shrubs OR a beach with many sand dunes and no grass. Explain
The beach with many sand dunes and no grass will erode faster because there is nothing to keep the sand from washing away. The roots of the grass and shrubs help keep the sand in place.

Deserts experience a lot of wind erosion. Describe the relationship between rainfall, vegetation (plants), and erosion in the desert.
Answers will vary. Possible answers may include the following: There is very little rainfall in the desert, so plants cannot grow. Since there are very few plants, the wind easily moves the sand around and causes changes to the land. If there were more plants, the plants would help hold the sand in place.
