Hydrosphere

The hydrosphere is the combined mass of water found on, under, and over the surface of a planet. It includes water in the form of liquid, solid, and gas, and encompasses oceans, rivers, lakes, glaciers, groundwater, and atmospheric water vapor.

Composition of the Hydrosphere

The hydrosphere is primarily composed of water, with about 97% of the Earth's water being found in oceans and seas. The remaining 3% is freshwater found in rivers, lakes, groundwater, and glaciers.

Importance of the Hydrosphere

The hydrosphere plays a crucial role in supporting life on Earth. It regulates the climate, transports nutrients, provides habitat for countless species, and is a vital resource for human activities such as agriculture, industry, and recreation.

Hydrosphere and the Water Cycle

The water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. This includes processes such as evaporation, condensation, precipitation, and runoff, all of which are driven by solar energy and gravity.

Human Impact on the Hydrosphere

Human activities, such as pollution, deforestation, urbanization, and climate change, have a significant impact on the hydrosphere. These activities can lead to water pollution, habitat destruction, alteration of natural water flow, and disruption of the water cycle, affecting both the environment and human well-being.
