Water Cycle

Front

What is the water cycle?

Back

The water cycle is the continuous process by which water moves from the Earth's surface to the atmosphere and back, involving processes like evaporation, condensation, and precipitation.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas, usually when it is heated.

Front

What is condensation?

Back

Condensation is the process by which water vapor (gas) cools and changes back into liquid water, forming droplets.

Front

What is precipitation?

Back

Precipitation is any form of water that falls from the atmosphere to the Earth's surface, including rain, snow, sleet, and hail.

Front

What is water vapor?

Back

Water vapor is the gaseous form of water that is present in the air.

Front

How does temperature affect evaporation?

Back

Evaporation happens faster at higher temperatures because heat provides energy for water molecules to escape into the air.

Front

What role do plants play in the water cycle?

Back

Plants contribute to the water cycle through a process called transpiration, where they release water vapor into the air.

Front

What is the difference between evaporation and boiling?

Back

Evaporation occurs at any temperature when water changes to gas, while boiling happens at a specific temperature (100°C or 212°F at sea level) when water rapidly changes to gas.

Front

What is the significance of the water cycle?

Back

The water cycle is essential for replenishing freshwater sources, supporting ecosystems, and regulating climate.

Front

What happens to water during a drought?

Back

During a drought, there is less precipitation, leading to reduced water availability in rivers, lakes, and reservoirs.
