Study Notes
Hydrosphere
- 71% of Earth's surface is covered by water.
- The hydrosphere is the part of Earth's atmosphere containing water.
Hydrologic Cycle (Water Cycle)
- The movement of water on Earth.
- Includes reservoirs (places where water stays) and pathways (processes of moving water between systems).
Processes in the Water Cycle
- Evaporation: Liquid water turning into water vapor.
- Transpiration: Water released from plant leaves into the atmosphere.
- Sublimation: Ice turning directly into water vapor.
- Condensation: Water vapor turning into liquid or solid water.
- Precipitation: Water falling from the atmosphere (rain, snow, etc.).
- Infiltration: Water soaking into the ground.
Earth's Water Budget
- The total amount of water on Earth.
Water Distribution
- Ocean Water: 97.5%
-
Freshwater: 2.5%
- Glaciers: 68.7%
- Groundwater: 30.1%
- Permafrost: 0.8%
- Surface and Atmospheric Water: 0.4% (mostly freshwater lakes).
Residence Time
- The amount of time water spends in a particular location.
