Evaporation

Answer 1

Water droplets are heated and become water vapour and rise

Question 2

Answer 4

Leaves and buildings catch rain as it falls and then stores the water

Question 5

Precipitation

Answer 5

As water vapour rises, it cools, and then it eventually turn back into water droplets

Question 8

Infiltration

Answer 8

Water moves downwards into the soil from the surface

Question 9

Soil moisture storage

Answer 9

Water fills the pores in-between the soil particles

Question 10

Percolation

Answer 10

Water moves deep downwards into the permeable rock

Question 11

Groundwater flow

Answer 11

Water flows very slowly horizontally towards the river through the groundwater rocks
