Closed System - There is a fixed amount of water in the Cycle.

STORES:

The Atmosphere
- Stored as Water Vapour or Minute Droplets.
The Land
- Rivers, Lakes, Reservoirs, Vegetation, Groundwater.
- Mostly liquid, occasionally in Solid Form.
The Sea
- Over 95% of Earth's water.
- Mostly liquid, occasionally solid form, in glaciers.

FLOWS:

The transfer of water between stores.

Evaporation
- Water converted from a liquid to a gas.
Transpiration
- The liquid plants have absorbed is 'breathed' into the atmosphere as water vapour.
Condensation
- Water vapour in the atmosphere cools and turns to liquid.
Precipitation
- Transfer of water in any form, from the atmosphere to the land/sea.
Overland Flow
- Water that hits the ground, entering a stream, river or lake. AKA, Run Off.
Infiltration
- Movement of water through the soil and rock into the groundwater.
