rivers

Question 1

the rivers transform the landscape in what three ways

Answer 1

EROSION -by wearing it away
TRANSPORTATION - moving its load downstream
DEPOSITION - dropping its load

Question 2

rate of river erosion depends on

Answer 2

size - erodes faster when in flood
speed - faster the river the more power
hardness of rocks - certain rocks erode quicker

Question 3

what influences the speed of the river

Answer 3

Gradient- steeper the slope the faster the river
Volume of water - greater discharge
Roughness of channel- smooth channel less friction
Shape of rive channel- small perimeter less friction

Question 4

rivers erode through what processes

Answer 4

hydraulic action
abrasion
solution/ corrosion
attrition

Question 5

different types of erosion in a river channel

Answer 5

vertical -erodes the river bed
lateral- erodes the side of he river
headword -erodes backwards

Question 6

4 processes of river transpotation

Answer 6

1 solution
2 suspension
3 salutation
4 traction

Question 7

process of deposition

Answer 7

the river loses speed

there is a reduction of water in the channel

Question 8

3 stages of the river

Answer 8

1 Youthful - upper
2 Mature - middle
3 Old- lower

Question 9

Characteristics of the youthful stage

Answer 9

steep
fast
lost of water
lots of erosion

Question 10

Characteristics of the mature stage

Answer 10

starts to slow down
more water
still erosion
some deposition

Question 11

characteristics of the old stage

Answer 11

moves more slowly
more water
mainly deposition
some erosion

Question 12

how are interlocking spurs formed

Answer 12

river flows around the hard rock while eroding downwards
