Interception
The capture of rainwater by leaves

Evapotranspiration
When leaves evaporate and transpire.
3 of 21
Surface run-off
Rainwater that runs across the surface of the ground

Condensation
The changing of a gas into a liquid
5 of 21
Aquifer
The water stored in rocks
6 of 21
Hydrosphere
All the waters on the Earth’s surface, such as lakes and seas
7 of 21
Hydrological cycle
The water is recycled again and again through evaporation, condensation and water transfers like surface run-off.
8 of 21
Closed system
A system closed but energy may be transferred between the system and its surroundings.
9 of 21
Infiltration
The soaking of rainwater into the ground
10 of 21
Percolation
When the water on the surface of Earth seeps down underground. It later forms aquifers in the low-lying regions.

Water stress
Occurs when the demand for water exceeds the amount available.
17 of 21
Water scarcity
Water stress and scarcity occurs when the demand for water exceeds the available amount during a period of time.
18 of 21
Physical scarcity
Occurs when demand exceeds supply
19 of 21
Economic scarcity
When people simply cannot afford water, even if it is available
20 of 21
Appropriate or intermediate technology
A technology that the local community is able to use relatively easily without much cost
