water cycle

Front

Which best explains why runoff is important?

Back

It returns water to other locations on Earth

Answer explanation

Runoff is important because it returns water to other locations on Earth, helping to replenish rivers, lakes, and groundwater. This process is essential for maintaining the water cycle and supporting ecosystems.

Front

Snow, sleet, hail, and rain are all examples of  ________________.

Back

precipitation

Answer explanation

Snow, sleet, hail, and rain are all forms of water that fall from the atmosphere to the ground. This process is known as precipitation, making it the correct choice among the options provided.

Front

What is it called when WATER is FORMED from an LIQUID to a WATER VAPOR or an [GAS]?

Back

EVAPORATION

Answer explanation

The process of WATER changing from a LIQUID to a WATER VAPOR (GAS) is called EVAPORATION. This occurs when heat causes the liquid water to gain energy and transition into vapor.

Front

What is it called when plants give off water vapor as a waste product?

Back

transpiration

Answer explanation

The process by which plants release water vapor as a waste product is called transpiration. This is essential for regulating water and nutrient flow within the plant.

Front

When water _________, drops of water form.

Back

Condenses

Answer explanation

When water condenses, it changes from a gas to a liquid, forming drops of water. This process occurs when water vapor cools and loses energy, leading to the formation of liquid water droplets.

Front

What is A? Options: Evaporation, Condensation, Precipitation, Runoff

Back

Evaporation

Answer explanation

A is Evaporation, which is the process where liquid water turns into vapor due to heat. This is a key part of the water cycle, leading to cloud formation and precipitation.

Front

What is B? Options: Evaporation, Condensation, Precipitation, Runoff

Back

Condensation

Answer explanation

B is condensation, which is the process where water vapor cools and changes into liquid water, forming clouds. This is a key part of the water cycle, distinct from evaporation, precipitation, and runoff.

Front

What is precipitation?

Back

The part of the water cycle when clouds get heavy and can no longer hold the liquid water. This causes the water to fall from the sky to the earth as rain, snow, sleet, or hail.

Answer explanation

Precipitation occurs when clouds become heavy with water and can no longer hold it, resulting in water falling to the earth as rain, snow, sleet, or hail. This is the correct definition of precipitation.

Front

What is condensation?

Back

The part of the water cycle when the water vapor in the air gets cold. The water turns back into a liquid and forms clouds.

Answer explanation

Condensation is when water vapor in the air cools down, turning back into liquid water, which forms clouds. This process is essential in the water cycle, distinguishing it from evaporation and precipitation.

Front

What is evaporation?

Back

The part of the water cycle when the sun heats up water, turning it from a liquid into water vapor or steam. It rises from the ground into the air.

Answer explanation

Evaporation is when the sun heats water, converting it from a liquid to vapor or steam, which then rises into the air. This process is a key part of the water cycle.
