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 (water vapor) due to heat from the sun.

Front

What is condensation?

Back

Condensation is the process by which water vapor cools and changes back into liquid water, forming clouds.

Front

What is precipitation?

Back

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

Front

What role does the sun play in the water cycle?

Back

The sun provides the energy needed for evaporation, which is the first step in the water cycle.

Front

What is fresh water?

Back

Fresh water is water that has low concentrations of dissolved salts, found in rivers, lakes, and streams.

Front

What is the difference between salt water and fresh water?

Back

Salt water contains a high concentration of dissolved salts, primarily found in oceans, while fresh water has low salt content.

Front

How do clouds form?

Back

Clouds form when water vapor in the air cools and condenses into tiny water droplets or ice crystals.

Front

What happens to water when it evaporates from the ocean?

Back

When water evaporates from the ocean, it leaves behind salt and other impurities, resulting in pure water vapor.

Front

What is the significance of the water cycle for life on Earth?

Back

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