Hydrosphere

The hydrosphere is the combined mass of water found on, under, and above the surface of a planet. It includes water in the form of liquid, solid (ice), and gas (water vapor). The Earth's hydrosphere is a critical component of the planet's ecosystems and plays a vital role in supporting life.

Key Concepts

• Water Distribution: The hydrosphere encompasses all water bodies, including oceans, rivers, lakes, and groundwater.
• Water Cycle: The continuous movement of water on, above, and below the surface of the Earth, driven by processes such as evaporation, condensation, precipitation, and runoff.
• Importance: The hydrosphere sustains life, influences climate, and supports various human activities such as agriculture, transportation, and recreation.
