Waterfalls and Interlocking Spurs

Question 1

where are the erosional features often found

Answer 1

in the upper course of the river

Question 2

how is a waterfall formed

Answer 2

it forms when there are horizontal bands of hard rock positioned over exposed, soft rock

Question 3

what type of rock erodes more quickly

Answer 3

soft rock

Question 4

in the upper course of a river, the water is less power - how does this affect erosion

Answer 4

there is more vertical erosion as the river is less powerful, so material cannot be moved in suspension and is instead moved along the river bed using traction or saltation

Question 5

how is a V-shaped valley created

Answer 5

through erosion and the movement of weathered material at the sides of the river

Question 6

what are interlocking spurs

Answer 6

land which link together like the teeth of a zip

Question 7

how are interlocking spurs created

Answer 7

if there are areas of hard rock which are harder to erode, the river will bend around them - creating interlocking spurs
