Which example is a form of precipitation?

• Dew

• Fog

• Frost

• Hail

As a part of the water cycle, water from Earth's surface enters the clouds and finally falls back to the ground in the form of rain. What is the correct sequence of processes water undergoes?

• Evaporation, Condensation, Precipitation

• Precipitation, Condensation, Evaporation

• Condensation, Evaporation, Precipitation

• Evaporation, Precipitation, Condensation

What would happen if the Sun is removed from the water cycle?

• The water cycle would not include precipitation but would continue with groundwater flow.

• The water cycle would no longer occur because the Sun provides the energy for evaporation and transpiration.

• The water cycle would no longer occur because the Sun provides energy for the formation of clouds.

• The water cycle would not include evaporation and transpiration but would continue with condensation.

A student draws a model to represent the precesses involved in the water cycle, as shown. To which process is the formation of clouds related?

• Condensation

• Evaporation

• Freezing

• Melting

The image shows various stages in the water cycle. During which stage does water flow back towards the sea as runoff?

• W

• X

• Y

• Z

On Earth, what process generates most of the water vapor?

• Condensation

• Evaporation

• Precipitation

• Transpiration

Rain and snow are two different forms of precipitation that fall on Earth's surface. Which factor is responsible for there being different forms of precipitation?

• Evaporation

• Run-off

• Temperature

• Transpiration

What is precipitation?

• Sweat from our bodies on hot days

• Warm rain but not cold snow or sleet

• Gas that we use in furnaces or ovens

• Any form of water that falls from the sky

What is the energy source that drives the water cycle?

• The moon T

• The heat from our home in the winter all around the world

• The sun

• he heat generated solely from the core of the earth

What are formed when water vapor condenses?

• Clouds

• Mountains
