Hydrosphere

The hydrosphere is the combined mass of water found on, under, and above the surface of a planet. This includes water in the form of liquid, solid (ice), and gas (water vapor). The Earth's hydrosphere is made up of oceans, seas, rivers, lakes, groundwater, and glaciers.

Key Concepts

• Water distribution on Earth
• Properties of water
• Water cycle
• Oceans and seas
• Rivers and lakes
• Groundwater
• Glaciers and ice caps
