landform processes and change

Question 1

what causes river landforms to change over time

Answer 1

fluvial erosion, transportation, deposition

Question 2

erosional processes of a river channel

Answer 2

abrasion, hydraulic action, solution

Question 3

erosional processes of the river bed load

Answer 3

attrition, abrasion

Question 4

fluvial

Answer 4

referring to a river and its landforms

Question 5

erosion

Answer 5

the wearing away of the land

Question 6

transportation

Answer 6

the movement of material by the flow of water

Question 7

deposition

Answer 7

the dropping of materials carried by the river

Question 8

bed load

Answer 8

the material carried by the river being bounced or rolled along its bed

Question 9

meander

Answer 9

a bend in the river formed by lateral erosion

Question 10

lateral erosion

Answer 10

sideways erosion

Question 11

abrasion (river bed erosion)

Answer 11

stones and material carried by the river hitting the river bed and banks become eroded themselves to become rounder and smaller

Question 12

hydraulic action

Answer 12

the sheer force of water hitting the river bed and banks, compressing air in gaps in the soil and rock which causes material to be pushed away

Question 13

abrasion (river channel)

Answer 13

stones and material carried by the river hitting the river bed and banks, wearing them away

Question 14

solution

Answer 14

the slightly acidic river water dissolves chalk and limestone rocks which are made from calcium carbonate

Question 15

attrition

Answer 15

stones carried by the river collide together and are broken down, becoming rounder and smaller
