The Hydrosphere
The hydrosphere includes all water on Earth - oceans, rivers, lakes, groundwater, and ice - essential for climate, life, and the water cycle
Core concept
Oceans make up the largest part of the hydrosphere, covering about 71% of Earth's surface and containing about 97% of Earth's water.
How it works
Freshwater sources, like rivers, lakes, and groundwater, make up a small percentage of total water but are essential for drinking and agriculture.
Why it matters
The water cycle continuously moves water between the hydrosphere, atmosphere, and land through evaporation, condensation, and precipitation.
Key detail
Understanding the hydrosphere helps us appreciate water's importance for climate regulation, ecosystems, and human survival.
