Water and Wind Erosion

Question 1

Throughout the reflection, make sure that you have the copy of the student guide, PDF or Word and your data tables. Fill in the terms that complete the statements. In this lab, you observed how different factors such as velocity, gradient, and , or amount of water in a stream, affect the rate of , the transport of materials from one area to another by water.

Part 1: volume; Part 2: erosion

Question 2

How did changing from a light drizzle to a downpour affect the river and the sediment in it? Check all that apply.The river increased its slope.The volume of the river decreased.The velocity of the river increased.There was more erosion in the stream.The type of sediment that moved changed.

Revolt · Accepted Answer

C: The velocity of the river increased.; D: There was more erosion in the stream.; E: The type of sediment that moved changed.

Question 3

Which conditions resulted in the erosion of larger rocks, like the one circled in the image? Check all that apply.

Question 5

A stream table is a tool used to show how water causes erosion. Water from the left side of the table is added to model a stream.Suppose a block of wood is placed under the left edge of the table.Which characteristic of the stream is changed?

Revolt · Accepted Answer

A: gradient of the stream

Question 6

Suppose a block of wood is placed under the left edge of the table. How would the new slope affect the rate of erosion? Where would most of the sand be deposited?

Revolt · Accepted Answer

A: There would be more erosion.

Question 7

The Colorado river flows through the Grand Canyon. Which characteristic of the river is directly affected by the amount of precipitation in this area? In which month would there be the most erosion where the river flows through?

Revolt · Accepted Answer

Selection 1: volume; Selection 2: February
