Chapter 6

Question 1

What is erosion? What are some agents of erosion?

Answer 1

Erosion is the removal of weathered material from one location to another. Some agents of erosion include water, wind, snow, sleet, glaciers, and gravity.

Question 2

What can increase the rate of erosion?

Answer 2

The climate, weather, type of rock, and topography can all increase the rate of erosion.

Question 3

What is deposition?

Answer 3

Deposition is the laying down or settling of eroded material.

Question 4

What are landforms created by erosion?

Answer 4

Some landforms created by erosion are mountains, sea cliffs, canyons, U-shaped valleys, sea caves, etc.

Question 5

What are landforms created by deposition?

Answer 5

Some landforms created by deposition are sand dunes, alluvial fans, moraines, streams, lakes, etc.

Question 6

What are the three types of water erosion?
see textbook!

Answer 6

The three types of water erosion are:
Stream Erosion- the three stages of stream development, young, mature, old
Coastal Erosion- how erosion happens at the coasts,
Groundwater Erosion- moves sediment and rock away and forms caves

Question 7

How does water erosion and deposition change Earth’s surface?

How does wind erosion and deposition change Earth’s surface?

Answer 7

Erosion takes sediment away, carves out areas, and breaks down different areas. Deposition is building up Earth’s surface,

Question 8

What are some ways gravity shapes Earth’s surface?

Answer 8

When gravity shapes Earth’s surface, it is called mass wasting. When mass wasting happens, gravity pulls things down. Some types of mass wasting are mudslides, rockfall, landslides, slump, etc.

Question 9

What are the two types of glaciers? How do glaciers affect Earth’s surface?

Answer 9

The two types of glaciers are ice sheets and alpines. Glaciers form U-shaped valleys, hanging valleys, cirques, aretes, and horns. These are usually formed by alpine glaciers.

Question 10

delta

Answer 10

large deposit of sediment that forms where a stream enters a large body of water

Question 11

deposition

Answer 11

laying down or settling of eroded material

Question 12

erosion

Answer 12

removal of weathered material from one location to another

Question 13

process

Answer 13

ongoing event or series of related events

Question 14

abrasion

Answer 14

grinding away of rock or other surfaces as particles carried by wind, water, or ice scrape against them

Question 15

dune

Answer 15

pile of windblown sand

Question 16

loess

Answer 16

crumbly, windblown deposit of silt and clay

Question 17

longshore current

Answer 17

flows parallel to the shoreline

Question 18

meander

Answer 18

broad, C-shaped curve in a stream

Question 19

glacier

Answer 19

large mass of ice that formed on land and moves slowly across Earth’s surface

Question 20

landslide

Answer 20

rapid downhill movement of soil, loose rocks, and boulders

Question 21

mass wasting

Answer 21

downhill movement of a large mass of rocks or soil because of gravity

Question 22

moraine

Answer 22

mound or ridge of unsorted sediment deposited by a glacier

Question 23

outwash

Answer 23

layered sediment deposited by streams of water that flowed from a melting glacier

Question 24

talus

Answer 24

pile of angular rocks and sediment from a rockfall

Question 25

till

Answer 25

mixture of various sizes of sediment deposited by a glacier
