What is water cycle?

Question

Answer

The process by which water continually changes its form and circulates between oceans, atmosphere and land is known as water cycle

Answer

The journey of water from the land to the sky and back to land is called water cycle.

Answer

The Water Cycle

The water cycle, also known as the hydrological cycle, is the continuous movement of water on, above, and below the Earth's surface. It involves the processes of evaporation, condensation, precipitation, and runoff, which work together to circulate water throughout the planet. This natural cycle plays a crucial role in maintaining the Earth's water supply and regulating the climate.

Evaporation:
- Water from oceans, lakes, rivers, and other bodies of water is heated by the sun and turns into vapor, a gas form of water.
- This process is called evaporation, and it occurs when the heat energy from the sun causes the water molecules to gain enough energy to break free from the liquid and become a gas.

Condensation:
- As the warm moist air rises into the atmosphere, it cools down and the water vapor begins to condense.
- Condensation occurs when the water vapor changes back into liquid water, forming clouds. This process is similar to the droplets that form on a cold glass of water on a hot day.

Precipitation:
- When the condensed water droplets in the clouds become too heavy, they fall back to the Earth's surface as precipitation.
- Precipitation can take various forms such as rain, snow, sleet, or hail, depending on the temperature and atmospheric conditions.

Runoff:
- Once the precipitation reaches the Earth's surface, it can either be absorbed into the ground (infiltration) or flow over the surface (runoff).
- Runoff occurs when the ground is saturated, or impermeable surfaces like concrete prevent water from seeping into the ground.
- The runoff collects in rivers, lakes, and oceans, replenishing the water bodies.

Importance and Impact:
- The water cycle is essential for maintaining the Earth's water supply, as it redistributes freshwater resources across different regions.
- It helps sustain ecosystems by providing water for plants, animals, and humans to survive.
- The water cycle also plays a crucial role in regulating the Earth's temperature and climate. Evaporation and condensation release or absorb heat energy, influencing weather patterns and the distribution of heat around the globe.

In conclusion, the water cycle is a continuous and dynamic process that ensures the circulation of water on Earth. Through evaporation, condensation, precipitation, and runoff, water is constantly moving, changing states, and replenishing the planet's water sources. This natural cycle is vital for maintaining life and regulating the Earth's climate.
