unit 2 lesson 2

Question 1

how does wind speed affect sediment movement

Answer 1

the faster wind the faster the sediment moves

Question 2

what does abrasian mean

Answer 2

the process of scraping or wearing something away.

Question 3

What is a dune

Answer 3

mounds of wind deposited sand
appear in lakes desserts and oceans

Question 4

what is a loess

Answer 4

thick deposits of wind blown fine sediment

Question 5

explain desert pavement and how it is it formed

Answer 5

deflation of the removal of line sediment by wind/wind erosion

Question 6

describe glacier formation

Answer 6

compacted snow by natural forces
the oldest snow is at the bottom and the newest is at the top

Question 7

describe how glaciers shape the land

Answer 7

the glaciers will melt and bring sediment down
carve bowl shape depression

Question 8

describe the processes of erosion and deposition

Answer 8

gravity pulls on sediments moving it
causes creep mudslides and avalaches

Question 9

how does mass movement can occur

Answer 9

creep gravity and steep slopes

Question 10

define glacier

Answer 10

large mass moving ice that forms by the compacting of snow by natural forces

Question 11

define glacier drift

Answer 11

all materials carried and deposited by a glacier

Question 12

what is creep

Answer 12

extremly slow movement of material down slope

Question 13

define rockfall

Answer 13

loose rocks fall down on a steep slope

Question 14

define landslide

Answer 14

sudden and rapid movement of a large amount of material down slope

Question 15

define mudflow

Answer 15

rapid movement of a large mass of mud
