Answer 0

Weathering

Question 1

What are solid particles that are moved from one place to another?

Answer 1

Sediments

Question 2

What kind of weathering takes place when forces such as water and ice break down rock?

Answer 2

Mechanical weathering

Question 3

What kind of weathering happens when the actual minerals that make up the rock change?

Answer 3

Chemical weathering

Question 4

What is the process by which soil and sediments are transferred from one location to another?

Answer 4

Erosion

Question 5

What is the process of adding sediments to a new place after being carried from another?

Answer 5

Deposition

Question 6

About how much salt do rivers carry each year?

Answer 6

About 4 billion tons

Question 7

How does water shape earths landscapes?

Answer 7

By breaking down rocks which makes sediments and they move from place to place.

Question 8

What is the source of much salt in ocean water?

Answer 8

Rivers.

Question 9

Why do sediments settle out of water as it slows down?

Answer 9

As the water slows down it was less energy. It can’t carry as much sediment.

Question 10

What are 4 wave characteristics?

Answer 10

Crest, trough, amplitude, as wavelength

Question 11

True or false?

Water that freezes in cracks of rocks can split them.

Answer 11

True

Question 12

True or false?

Plant roots help break down rocks and hold soil in place.

Answer 12

True

Question 13

Farmers have learned to plant cover crops to prevent soil ______.

Answer 13

Erosion

Question 14

Canyons are formed by ______ _____.

Answer 14

Moving water

Question 15

True or false?

A floodplain is likely to have poor soil.

Answer 15

False

Question 16

What is the agent of erosion that forms sand dunes?

Answer 16

Wind.

Question 17

How do drought conditions cause the soil to be easily eroded by wind?

Answer 17

If there is no water in the soil it will be easy to blow away.

Question 18

What is a floodplain?

Answer 18

Part of the landscape that is likely to receive the overflow water and sediment from a flooded river.

Question 19

As water slows down, does it have more or less energy?

Answer 19

Less energy.

Question 20

What kind of sediments do waves carry?

Answer 20

Stones and sand

Question 21

How are sandbars created?

Answer 21

By the movement of water, it can move materials from the shoreline to an area in the water away from the shore.

Question 22

Where does black sand come from?

Answer 22

Hawaii.

Question 23

Water flows in a river because of _______.

Answer 23

Gravity

Question 24

How do erosion and deposition affect beaches?

Answer 24

Erosion blows the sand dunes down

Question 25

Describe 2 examples of mechanical weathering.

Answer 25

1. Water goes into cracks of rocks and freezes. Then it expands the rock. 2. Soil grows in cracks of rocks. Plants grow. The roots push the cracks open.

Question 26

Describe how water running downhill is the main process that shapes Earth's landscapes.

Answer 26

Over years, water digs deeper into earth's surface to form deep canyons.
