Saltwater

Makes up 97% of Earth's water supply, with an average salt concentration of 3.5% in oceans.

Freshwater

Only 3% of Earth's total water supply, essential for drinking, mostly occurs as ice, snow, or underground.

Three States Of Water

Solid, Liquid, Gas; changes with heat (evaporation) or cold (freezing).

Groundwater

Freshwater underground, one-third of the world's freshwater, stored in aquifers, always moving.

Ice Sheets

Large glaciers covering land, like in Greenland and Antarctica, formed similarly to mountain glaciers.

Water Cycle

Continuous movement of water between Earth's surface and atmosphere, driven by the sun's thermal energy.

Definitions

Evaporation, Melting, Freezing, Sublimation, Condensation, Deposition - processes in the water cycle.

Watershed

Land area draining into a main water body, affected by natural events and human activities.

Mountain Glaciers

Masses of ice and snow moving down slopes due to gravity, formed from compacted snow in freezing temperatures.
