The water cycle, also known as the hydrological cycle, is a continuous process through which water circulates on Earth. It involves various stages, including evaporation, condensation, precipitation, and runoff. This natural cycle ensures the movement and redistribution of water from the Earth’s surface to the atmosphere and back again.

B. Explanation of the Key Processes Involved: Evaporation, Condensation, Precipitation, and Runoff

Evaporation: Evaporation is the process by which water changes from its liquid state to a gaseous state. It occurs when heat energy from the sun causes the water on the Earth’s surface, such as oceans, lakes, and rivers, to vaporize and rise into the atmosphere. Additionally, plants and trees release water vapor through a process called transpiration. This water vapor then combines with the air, forming invisible water vapor molecules.
Condensation: As the water vapor rises into the cooler upper atmosphere, it begins to cool and condense into tiny water droplets or ice crystals. These droplets or crystals form clouds, which are visible masses of suspended water particles. Condensation is a crucial step in the water cycle as it allows the water vapor to transition back into its liquid or solid form.
Precipitation: Precipitation occurs when the condensed water droplets or ice crystals in the clouds combine and grow in size, eventually becoming too heavy to remain suspended in the air. The water droplets or ice crystals fall from the clouds and reach the Earth’s surface as rain, snow, sleet, or hail. Precipitation is a vital part of the water cycle as it replenishes the Earth’s water sources, such as rivers, lakes, and groundwater.
Runoff: After precipitation, the water on the Earth’s surface can take different paths. Some of it may flow over the land as runoff, moving across the surface and eventually reaching streams, rivers, and oceans. Runoff plays a crucial role in transporting water and nutrients, replenishing bodies of water, and shaping the Earth’s landscape.

Understanding these key processes of evaporation, condensation, precipitation, and runoff helps us comprehend the complexity of the water cycle and its role in sustaining life on Earth.
