Amazon Physical factors, stores and flows of water #4

Question 1

How does geology affect the water cycle?

Answer 1

Large areas of the basin are ancient shields of impermeable, crystalline rock resulting in rapid run off.

Limestone and sandsone areas store water and reduce run-off.

Question 2

How does relief affect the water cycle?

Answer 2

Mostly gentle relief so water moves slowly as throughflow or overland flow to rivers.

In the west the Andes creates steep slope= rapidly overland flow regularly indundating floodplains and stored for months =slowing movement of rivers.

Question 3

How does temperature water cycle?

Answer 3

High temp. so rapid evapotranspiration so convection is strong=high humidity=thunderstorms develop and intense precip.
