the cycle in which water moves around the world by changing states.

hail, sleet, snow, and rain are all examples of....

collide to form larger droplets that falls as rain

provides energy to power cycle

solid, liquid, and gas

depth at which loose rocks and soil below Earth's surface are saturated with water; upper boundary of aquifer

When water falls back to Earth's surface, it may be collected in oceans, lakes, or rivers.

falls as snow flakes

when water loses thermal energy (heat)

when liquid water seeps through soil & rocks; is source of water for underground springs & wells

when water vapour loses thermal energy (heat) and becomes a liquid

water from precipitation & snowmelt that flows over Earth's surface

stays the same when water changes state in the water cycle

when a solid water gains thermal energy (heat)

a large area of ice that permanently covers land & glaciers

the state of change from gas to solid when gas loses thermal

slightly less dense than liquid water

Earth's surface water freezes and forms ice in...

when water absorbs thermal energy to become gas

the geological formation of loose rocks or soil that is saturated with groundwater.

when thermal energy is added to solid ice to become gas

fallen snow which may gradually accumulate as...

surface water evaporates and snow and ice sublime from Earth's surface to become...
