• An area of land where precipitation collects and drains off into a common outlet

• A storage area for groundwater

• A type of plant storage

Which process returns water to the atmosphere in vapor form?

What is the role of interception storage in a drainage basin?

• To store water in the soil

• To allow water to flow over the ground

• To temporarily store water on plant leaves

• To collect water in underground rocks

What is the term for water flowing slowly below the ground until it reaches a river or lake?

What is the main cause of increased flood risk due to deforestation?

• Increased soil storage

• Faster overland flow

• More groundwater storage

• Slower throughflow

What happens during infiltration?

• Water evaporates into the atmosphere

• Water flows over the ground surface

• Water soaks down into the soil

• Water is stored in plant leaves

What is the purpose of soil storage in a drainage basin?
