The hydrological cycle, also known as the water cycle, is the continuous movement of water on, above, and below the surface of the Earth. It involves the processes of evaporation, condensation, precipitation, infiltration, runoff, and transpiration. Water evaporates from bodies of water and land surfaces, condenses into clouds, falls as precipitation, and then flows back into bodies of water or infiltrates into the ground to be taken up by plants or stored in underground aquifers. This cycle is essential for maintaining the Earth's water supply and regulating the climate.

Definition of the Hydrological Cycle:
The hydrological cycle is the continuous movement of water around the Earth's surface and atmosphere. It describes the interconnected processes of water storage, movement, and exchange between different reservoirs on the planet.
Key Components of the Hydrological Cycle:
- Evaporation: Water evaporates from oceans, lakes, rivers, and other water bodies, turning into water vapor that enters the atmosphere.
- Condensation: As water vapor cools in the atmosphere, it condenses to form clouds.
- Precipitation: Water vapor in clouds precipitates back to the Earth's surface in the form of rain, snow, sleet, or hail.
- Infiltration: Precipitation that falls on land can infiltrate the soil, becoming groundwater.
- Runoff: Precipitation that flows over the land surface rather than infiltrating becomes runoff, eventually reaching streams, rivers, and oceans.
- Transpiration: Plants absorb groundwater and release it into the atmosphere through their leaves as water vapor.
- Recharge: Water from precipitation, runoff, or groundwater can replenish underground aquifers.
Major Reservoirs in the Hydrological Cycle:
- Oceans: Hold the vast majority of the Earth's water (96.5%).
- Ice caps and glaciers: Store approximately 2.4% of the Earth's water.
- Groundwater: Accounts for about 1.7% of the Earth's water, stored in aquifers below the Earth's surface.
- Surface water: Includes lakes, rivers, streams, and wetlands, holding a small fraction of the Earth's water (0.01%).
- Atmosphere: Contains a small amount of water in the form of water vapor (0.001%).
Significance of the Hydrological Cycle:
The hydrological cycle plays a crucial role in:
- Maintaining the Earth's water balance
- Shaping the Earth's surface through erosion and deposition
- Supporting ecosystems and biodiversity
- Regulating weather patterns
- Providing water resources for human civilization
