HW P5 CH.9 THE ATMOSPHERE AND WATER CYCLE

The Earth’s atmosphere is a layer of air. It is made up of gases in different amounts.
Which of these gases is found in the large amount in the air?

• Oxygen

• Nitrogen

• Hydrogen

• Carbon dioxide

Let’s find the role of heat from the Sun in the water cycle

Heat from the Sun causes the water in water bodies and the ground to . . . .

• Boil

• Freeze

• Condense

• Evaporate

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 does the precipitation means?

• Water running downhill

• Water heating up and rising as gas

• Water falling from the sky

•   Water vapor cooling to form clouds

During condensation process the water changes from ....

• Solid ice to liquid water

• Liquid water to water vapor (gas)

• Liquid water to solid (ice/snow)

• Water vapor (gas) to liquid water drops

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 not include evaporation and transpiration but would continue with condensation.

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

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