Hydrosphere

The hydrosphere refers to all the water on Earth, including water in the oceans, lakes, rivers, streams, glaciers, and underground water. It also includes water vapor in the atmosphere. The hydrosphere plays a crucial role in sustaining life on Earth and is an essential part of the water cycle.

Key Concepts to Understand:

• Water Cycle: The continuous movement of water on, above, and below the surface of the Earth. It involves processes such as evaporation, condensation, precipitation, and runoff.
• Oceans: The largest bodies of water in the hydrosphere, covering about 71% of the Earth's surface. They play a significant role in regulating the planet's climate and weather patterns.
• Rivers and Lakes: Bodies of freshwater that are essential for providing habitats for aquatic life and as sources of drinking water and irrigation.
• Water Conservation: The importance of conserving water resources and preventing pollution of water bodies to ensure sustainable access to clean water for all living organisms.
