Question 1

What is infiltration?

Answer 1

Water trickling slowly into the soil

Infiltration is the process by which water enters the soil from the surface.

Question 2

Define throughflow

Answer 2

Water moving downhill through soil

Throughflow refers to the lateral movement of water within the soil layer.

Question 3

What is overground flow?

Answer 3

Water moving quickly over the surface of the ground downhill towards a river

Overground flow is also known as surface runoff.

Question 4

What does transpiration refer to?

Answer 4

Water evaporated from the surface of plants

Transpiration is a key process in the water cycle, contributing to moisture in the atmosphere.

Question 5

Define groundwater flow

Answer 5

Water moving downhill towards a river through rocks very slowly underground

Groundwater flow is crucial for maintaining river levels and ecosystem health.

Question 6

What is percolation?

Answer 6

Water trickling very slowly down through porous rocks

Percolation is an important process for filtering water as it moves through the ground.
