Water Cycle (STAAR released questions)

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 accumulation.

Front

What happens during evaporation?

Back

Evaporation is the process where liquid water is heated by the sun and changes into water vapor (gas).

Front

What is condensation?

Back

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

Front

What is precipitation?

Back

Precipitation is when water falls from the atmosphere to the Earth's surface in the form of rain, snow, sleet, or hail.

Front

What is accumulation in the water cycle?

Back

Accumulation is when water gathers together in puddles, lakes, or oceans after precipitation.

Front

How does the sun affect the water cycle?

Back

The sun provides heat that warms the ocean, causing water to evaporate and eventually leading to cloud formation.

Front

What is runoff?

Back

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

Front

What role do clouds play in the water cycle?

Back

Clouds are formed from condensed water vapor and are essential for precipitation, returning water to the Earth's surface.

Front

What is the difference between evaporation and condensation?

Back

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

Front

What is the significance of the water cycle?

Back

The water cycle is crucial for maintaining the Earth's water supply, supporting ecosystems, and regulating climate.
