Answer 19

Geysers and hot springs

Question 20

What does not affect the depth of the water table below the ground?

Answer 20

Pollution

Question 21

What is a necessary condition for a river system to form?

Answer 21

Precipitation exceeds evapotranspiration

Question 22

How does a rivers velocity affect its erosive ability?

Answer 22

Faster rivers erode the channel more quickly than slower rivers

Question 23

What factors widen and deepen a river channel?
