ThinkUp Unit 13: Concept Check (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, precipitation, and runoff.

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas, usually due to heat from the sun.

Front

What is condensation?

Back

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

Front

What is precipitation?

Back

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

Front

What is runoff?

Back

Runoff is the water that flows over the ground surface and returns to bodies of water like rivers, lakes, and oceans.

Front

What is groundwater?

Back

Groundwater is water that seeps into the ground and fills the spaces in soil and rock, forming underground reservoirs.

Front

How does the sun affect the water cycle?

Back

The sun provides the heat necessary for evaporation, which is a key part of the water cycle.

Front

What happens to water when it rains?

Back

When it rains, some water falls into oceans, lakes, and rivers, while some seeps into the ground to form groundwater.

Front

What is the role of clouds in the water cycle?

Back

Clouds are formed by condensation and play a crucial role in transporting water vapor and eventually releasing it as precipitation.

Front

What is the difference between evaporation and condensation?

Back

Evaporation is the process of water turning into vapor, while condensation is the process of vapor turning back into liquid.
