The water cycle, also known as the hydrological cycle, is the continuous process of water movement from the Earth's surface to the atmosphere and back to the surface.
The water cycle has four main stages:
1. Evaporation: This occurs when the sun heats up bodies of water, causing water molecules to become vapor or steam. Evaporation also occurs from plants through a process called transpiration.
2. Condensation: The water vapor rises into the atmosphere and condenses into tiny water droplets in the form of clouds.
3. Precipitation: Water droplets in the clouds combine and grow until they become too heavy to stay aloft. They fall back to Earth in the form of rain, snow, sleet, or hail.
4. Runoff: The precipitation that falls on land can either be absorbed into the ground (infiltration) or flow across the surface of the land (runoff) into streams, rivers, lakes, and oceans. Some of the runoff is absorbed by plants and trees and is later released back into the atmosphere through transpiration.
The water cycle is a continuous process, and all stages are interdependent and essential for the health of the planet. It helps to regulate the climate and maintain the Earth's water balance, which is essential for the survival of plants, animals, and humans.

The water cycle is the natural process by which water is circulated through the environment. It involves the evaporation of water from the oceans and other bodies of water, its condensation into clouds, its precipitation back to the Earth's surface, and its eventual return to the oceans. This cycle is powered by the Sun's energy, and it is responsible for providing the Earth with fresh water.
The water cycle, also known as the hydrological cycle, describes the continuous movement and exchange of water on, above, and below the Earth's surface. It involves several key processes:
1. **Evaporation**: Water from oceans, rivers, lakes, and the Earth's surface is heated by the sun, causing it to change from liquid to vapor and rise into the atmosphere.
2. **Condensation**: As the water vapor rises, it cools and condenses into tiny water droplets or ice crystals, forming clouds in the atmosphere.
3. **Precipitation**: When the water droplets in clouds become too heavy to remain suspended, they fall back to the Earth's surface as precipitation. This can include rain, snow, sleet, or hail.
4. **Surface Runoff**: Precipitation that falls on the Earth's surface can flow into rivers, streams, and eventually make its way to the oceans or other bodies of water. This is known as surface runoff.
5. **Infiltration**: Some precipitation is absorbed by the ground and enters the soil, becoming groundwater. This water may be stored in underground aquifers for extended periods.
6. **Transpiration**: Plants absorb water from the ground through their roots and release it into the atmosphere through tiny openings in their leaves. This process is known as transpiration.
7. **Sublimation**: In areas with snow and ice, some of the frozen water can change directly from ice to water vapor in the atmosphere, a process called sublimation.
8. **Melting**: Snow and ice can melt when temperatures rise, returning water to the liquid state and potentially contributing to surface runoff or groundwater recharge.
9. **Advection**: Water vapor can be transported by wind and air masses, which can carry moisture to different regions before it condenses and falls as precipitation.
The water cycle is a fundamental natural process that plays a crucial role in maintaining Earth's ecosystems and providing freshwater resources for human and environmental needs. It helps distribute water across the planet, ensuring the availability of water for agriculture, drinking, and other essential purposes.
