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, and precipitation.

Front

What powers the Water Cycle?

Back

The Sun's energy powers the Water Cycle by providing the heat necessary for evaporation.

Front

What is evaporation?

Back

Evaporation is the process where liquid water changes into water vapor due to heat from the sun.

Front

What is condensation?

Back

Condensation is the process where water vapor 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 flow of water, from rain or melting snow, that moves across the ground and returns to bodies of water.

Front

What is accumulation in the Water Cycle?

Back

Accumulation is the process where water collects in large bodies like rivers, lakes, and oceans.

Front

How does the sun affect the Water Cycle?

Back

The sun provides the energy needed for evaporation, which is the first step in the Water Cycle.

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 atmosphere.

Front

What is the difference between evaporation and transpiration?

Back

Evaporation is the process of water turning into vapor from surfaces like lakes, while transpiration is the release of water vapor from plants.
