Front 1

The process of _____________ wears away suurface materials and move them from one location to another.

Back 1

erosion

Front 2

_____________ is the final stage of an erosional process.

Back 2

deposition

Front 3

T/F Gravity is the force of attraction that exsists between all objects.

Back 3

True

Front 4

When gravity alone causes materials to move downslope, this type of erosion is called

Back 4

mass movement

Front 5

____________ is a mass movement that happens wehn loose materials or rock layers slip down a slope

Back 5

slump

Front 6

______________ gets it name from the way sediments slowly inch their way down a hill

Back 6

creep

Front 7

Moving mass of ice and snow

Back 7

glacier

Front 8

The process by which rock pieces are lifted out by the glacial ice sheets

Back 8

plucking

Front 9

The mixture of different sixed sediments is called _______________.

Back 9

till

Front 10

such a rigde is called __________.

Back 10

moraine

Front 11

_____________-,it blows across loose sediment,removing small particles such as caly,silt,and sand.

Back 11

deflation

Front 12

when these windblown sediments strick rock,they erode by____________.

Back 12

abrasion

Front 13

these wind deposits of fine-grained sediments are known as_________.

Back 13

loess

Front 14

A deposit from a glaciers ice

Back 14

outwash

Front 15

Large blocks of rocks tumbling down a steep slope

Back 15

rockslide

Front 16

Deposits formed when windblown sediments pile up behind an obstacle

Back 16

dunes

Front 17

One way to reduce erosion

Back 17

planting

Front 18

an activity that can increase erosion on steep slopes

Back 18

building

Front 19

____________ are broad, step-like cuts in the side of slope

Back 19

Terraces

Front 20

________________ occur when berock is gourged by rock fragments

Back 20

grooves

Front 21

_____________ are bowl-shaped basins resulting from plucking on the side of a mountain.

Back 21

cirques

Front 22

Many farmland of the midwestern United States are on fertile soild evolved from ________ deposits

Back 22

loess

Front 23

__________ is similar to sandblasing

Back 23

abrasions

Front 24

Agents of erosion __________ sediments when they lose thier energy of motion

Back 24

drop sediments

Front 25

Creep Erosion

Back 25

1-The gound freezes
2-Expanding water in the soil
3-The frozen soil thaws
4-Seiments slowly fall downslope

Front 26

Glacial Erosion

Back 26

1-a glacier is formed
2-plucking occurs
3-Striations are gourged
4-The glacier loses energy
5-Till is deposited

Front 27

Compare and Contrast Slum and Creep?

Back 27

Slump takes place on steep slopes when loose materials slip downward;Creep takes place on hills where sediments mvoe very slowly downslope

Front 28

Sand dunes are found on the eastern and southeaster shores of Lake Michigan. They are not found on the western shore why?

Back 28

winds cause sand to build up on the beaches of the eastern and southeastern shores. these winds tend to blow the sand on the western ashore into the lake.

Front 29

How have volcano effeced the ice age?

Back 29

contributed to ice age

Front 30

Which are steeper younger mountains or older mountains

Back 30

younger mountains are usually steeper because as mountains get older mudlfows, rockslides, creep, and slump cuase the sloper of mountains to decrease

Front 31

Losse materials or rock layers slip downward

Back 31

slump

Front 32

large blocks of rocks break loose and tumble

Back 32

rockslides

Front 33

deposits from weosion are usually cone shaped masses

Back 33

mudflows

Front 34

This kind of erosion is common in areas when freezing and thawing occurs

Back 34

creep

Front 35

This erosion occurs happens when sediments move slowly down a slope

Back 35

creep

Front 36

The erosion is mass movement

Back 36

mudflows

Front 37

This erosion occurs after a heavy rain

Back 37

mudflows

Front 38

Signs warning people about this kind of erosion may be posted along the road

Back 38

rockslides
