Temperature change: cold to hot expanding and contracting.

Question 11

Erosion

Answer 11

The process that moves bits of rock or soil from one place to another

Question 12

Erosion is caused by

Answer 12

Gravity, water, wind and, ice/glaciers

Question 13

Deposition

Answer 13

The process in which sediment soils and rocks are added to a landform such as deltas, flood planes, sandbars, and dunes

Question 14

Deposition occurs when:

Answer 14

The forces moving sediments are no longer able to overcome the force of gravity and friction

Question 15

What affects transportation of sediment?

Answer 15

Running water is a primary agent of erosion.

Question 16

What depends on gradient(slope)and discharge (amount of water)

Answer 16

The velocity of running water

Question 17

As velocity increases

Answer 17

The size of particles carried increases(faster water larger particles)

Question 18

Young rivers

Answer 18

Fast flowing, V-shaped valleys, waterfalls, rapids.

Question 19

Mature rivers

Answer 19

Less energy, slower, meanders, sandbars

Question 20

Old rivers

Answer 20

Very slow, shallow, large amount of sediment deposited, many narrow channels call mom islands, deltas

Question 21

Features created by wind

Answer 21

Arches, sand dunes, mushroom rocks

Question 22

Features created by gravity

Answer 22

Landslides, mudflows, slump/creep

Question 23

Features created by glaciacion (glaciers)

Answer 23

U-shaped valleys, hanging valley, horn, moraine

Question 24

Coastline with more erosional features

Answer 24

Western us

Question 25

Coastline with more depositional features

Answer 25

Eastern US

Question 26

Eco regions

Answer 26

Area is defined by its environmental conditions especially climate landforms and soil characteristics

Question 27

Soil characteristics

Answer 27

Amount of vegetation
