Chapter 8

Question 0

dropping of sediment that occurs when an agent of erosion, such as gravity, a glacier, wind, or water, loses its energy and can no linger carry its load

Answer 0

deposition

Question 1

is a process that wears away surface materials and moves them form place to place

Answer 1

erosion

Question 2

any type of erosion that occurs as gravity moves materials down-slope

Answer 2

mass movement

Question 3

a type of mass movement that occurs when a mass of material moves down a curved slope

Answer 3

slump

Question 4

a type of mass movements in which sediments move down-slope very slowly; is common in areas of freezing and thawing, and can cause walls, trees, and fences to lean downhill

Answer 4

creep

Question 5

large, moving masses of ice and snow that change large areas of Earth’s surface through erosion and deposition

Answer 5

glacier

Question 6

process that adds gravel, sand, and boulders to a glacier’s bottom and sides was water freezes and thaws, breaking off pieces of surrounding rock

Answer 6

plucking

Question 7

mixture of differen-sized sediments that is dropped from the base of a retreating glacier and can cover huge areas of land

Answer 7

till

Question 8

large ridges of rocks and soil deposited by a glacier when it stops moving forward

Answer 8

moraine

Question 9

material deposited by meltwater from a glacier

Answer 9

outwash

Question 10

what are 3 ways to prevent erosion

Answer 10

retaining walls, vegetation, and wire/fences

Question 11

how dose a glacier form

Answer 11

more snow accumulates than melts over time you have a large mass covering a min. of 40 acres and many ft. deep

Question 12

why does a glacier flow down a hill

Answer 12

pressure causes the soil and snow to behave like a liquid and slowly flow downhill

Question 13

what is found at bottom of a glacier where it is under a large amount of pressure

Answer 13

blue ice

Question 14

what is the zone of flow

Answer 14

the blue ice

Question 15

what is the zone of accumulation

Answer 15

the top with new snow

Question 16

what are the 3 types of morains

Answer 16

terminal, medial, and lateral

Question 17

what is a cirque

Answer 17

circular formation in a mt.

Question 18

what is a horn

Answer 18

a 3 sided mt.

Question 19

what is a tarn

Answer 19

a cirque filled with h2o

Question 20

what are kettles

Answer 20

are formations made on plains by glaciers

Question 21

what are tills

Answer 21

unstratified deposits of small rock and soil (glacial dirt)

Question 22

what is calving and what does it make

Answer 22

a piece of ice ice breaks off into the ocean: icebergs

Question 23

what are fiords

Answer 23

are created when a glacier goes into the ocean and scrapes out the land. The glacier melts and the ocean floods the area previously covered by a glacier
