The Water Cycle

Front

What is condensation?

Back

The process by which molecules of water vapor become liquid water.

Front

What is surface runoff?

Back

The flow of water that occurs when excess stormwater, meltwater, or other sources flows over the Earth's surface.

Front

What is the water cycle?

Back

The movement of water between the atmosphere and Earth’s surface, including processes like evaporation, condensation, and precipitation.

Front

How does water from the ocean become precipitation?

Back

The sun warms the ocean; water evaporates and then condenses into clouds; precipitation falls to the ground.

Front

What is evaporation?

Back

The process by which water molecules in liquid water escape into the air as water vapor.

Front

What is precipitation?

Back

Any form of water, liquid or solid, that falls from the atmosphere and reaches the ground, such as rain, snow, sleet, or 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 transpiration?

Back

The process by which water is absorbed by plants and then released as water vapor into the atmosphere.

Front

What is the difference between evaporation and transpiration?

Back

Evaporation is the process of water turning into vapor from any surface, while transpiration specifically refers to water vapor released from plants.

Front

What is the significance of the water cycle?

Back

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