Erosion and Transportation Shaping The Land

Question 1

Name the four forms of erosion

Answer 1

• Hydraulic action
• Abrasion
• Attrition
• Solution

Question 2

Name the four forms of transportation

Answer 2

• Suspension
• Solution
• Traction
• Saltation

Question 3

Erosion:

How does Hydraulic action work?

Answer 3

Water is forced into cracks in the rock, then is compressed and forces the rock apart

Question 4

Erosion:

How does Abrasion work?

Answer 4

Loose rocks are thrown against the cliff wearing away at the rock like sandpaper

Question 5

Erosion:

How does Attrition work?

Answer 5

Loose rocks are swirled around and are worn in smaller, rounder pieces

Question 6

Erosion:

How does Solution work?

Answer 6

Seawater dissolves material from the rock

Question 7

Transportation:

How does Suspension work?

Answer 7

Fine sediment is carried along in suspension in the water

Question 8

Transportation:

How does Solution work?

Answer 8

Dissolved materials is carried along in solution-you can’t see it

Question 9

Transportation:

How does Traction work?

Answer 9

Large pebbles and cobbles are rolled along the seabed

Question 10

Transportation:

How does Saltation work?

Answer 10

Small pebbles are moved when one pebble hits another causing it to bounce
