Question 2

Transpiration

Answer 2

Water is absorbed by plants from the soil through their roots.

Question 5

Surface run-off

Answer 5

Question 6

Infiltration

Answer 6

Precipitation that falls onto the land can soak into the soil, refilling groundwater sources.

Question 7

Groundwater Flow

Answer 7

Water that infiltrates into the soil becomes groundwater, which slowly moves through underground aquifers.

Question 8

Question 9

Freezing

Answer 9

Converts water from the liquid state to the solid state, act as water storage.

Question 10

Melting

Answer 10

Converts ice and snow back into liquid form.

Question 11

Sublimation

Answer 11

Transforms a solid straight into to a gas (skips liquid phase)

Question 12

Deposition

Answer 12

Transforms gas into solid (skips liquid phase)

Question 13

Percolation

Answer 13

The movement of water through the soil and rock.
