Q

what best describes sediments deposited by glaciers and rivers

A

glacial deposits are unsorted and river deposits are sorted

14
Q

a sedimentary particle is dropped into a cyllinder of water. the particle will settle the fastes if it has

A

high density, large size and flattened shape

15
Q

what is the largest particle that can be kept in motion by a stream that has a velocity of 100 cm per second

A

pebble

16
Q

in wich type of landscape are meandering streams most likely foind

A

gently sloping plains

17
Q

what best describes a stream with a steep gradient

A

it flows rapidly producing a v shaped valley

18
Q

erosion

A

moves sed

19
Q

deposition

A

sed stops moving and piles up

20
Q

Rivers in

A

V shaped valleys

21
Q

stream velocity depends on two things

A

a- slope
b-stream discharge( amount of water in a stream)

22
Q

More discharge

A

faster water

23
Q

young stage

A

1- steep slope therefore fast water
2- downward erosion, making valley deeper
3- rapids and waterfalls
4- fairly straight

24
Q

mature stage

A

1- gentle slope therefore slow water
2- sideways eriosion, making valley wider
3- meanders develop –> oxbow lakes

25
Q

glaciers

A

huge moving ice (sediments)

26
Q

seds move in ice

A

erosion

27
Q

ice melts

A

deposition

28
