Water Cycle

The water cycle is the continuous circulation of water in nature. It involves the movement of water from one place to another through the processes of evaporation, condensation, precipitation, infiltration, and runoff. The water cycle is important for the survival of all living things on Earth because it ensures a constant supply of fresh water.

Processes involved in the water cycle:

- Evaporation: This is the process by which water changes from a liquid to a gas. It occurs when the sun heats up water bodies such as oceans, lakes, and rivers. The water molecules absorb energy and become vapor, which rises into the atmosphere.

- Condensation: This is the process by which water vapor in the atmosphere cools and changes back into liquid form. It occurs when the water vapor comes into contact with cooler air or surfaces. This process leads to the formation of clouds.

- Precipitation: This is the process by which water falls from the atmosphere to the Earth's surface in various forms such as rain, snow, sleet, or hail. Precipitation occurs when the clouds become saturated with water and cannot hold it anymore.

- Infiltration: This is the process by which water seeps into the ground and becomes groundwater. It occurs when the precipitation that falls on the ground is absorbed by the soil and rocks.

- Runoff: This is the process by which water flows over the surface of the Earth and collects in rivers, lakes, and oceans. It occurs when the ground is saturated with water and cannot absorb any more.

Importance of the water cycle:

The water cycle is important for various reasons:

- It helps to regulate the Earth's climate by distributing heat and moisture around the planet.

- It is responsible for the formation of weather patterns such as rain, snow, and storms.

- It provides a constant supply of fresh water for plants and animals to survive.

- It helps to recharge groundwater reserves, which are important sources of drinking water for humans.

- It supports various ecosystems such as wetlands, rivers, and oceans, which provide habitats for a wide range of plants and animals.
