The Water Cycle Vocabulary

Water Cycle Write what’s in orange only Cycle by which water moves around the Earth, changing both its phase (between solid to liquid to gas) and its location (in the oceans, in clouds, in streams and lakes, and in groundwater).

Liquid → gas

Gas → Liquid Condensation creates clouds

Water falls back to Earth; rain, snow, sleet & hail

The flow of water to a reservoir

Evaporation from plants Transpiration Evaporation from plants

Estuary A partially enclosed body of water where freshwater meets and mixes with salt water

River Basin/Watershed The drainage area of a river

Area covered by ocean water Ocean Basin Area covered by ocean water

Sublimation Solid gas; skipping the liquid phase.

Deposition Write what’s in orange only Where water vapor changes directly into ice (such as snowflakes and frost)

Downward movement of water Percolation Downward movement of water
