Weather and Water Cycle

The movement of water from Earth, to the atmosphere, and back to Earth

• A. atmosphere

• B. water cycle

• C. condensation

• D. air pressure

Every day on Earth, water in the oceans is heated by the sun. As the ocean water is heated, it goes into the air as vapor. The water vapor forms clouds, and then the water falls to the ground as rain, snow, sleet, or hail. Refer to the diagram above. What is the process in which water goes from the oceans into the air?

• A. condensation

• B. erosion

• C. evaporation

• D. melting

What is the source of most of the water that evaporates as part of the water cycle?

• A. ice from glaciers

• B. salt water from oceans

• C. fresh water from lakes and ponds

• D. groundwater from below Earth’s surface

A model of the water cycle was made using an aquarium with a glass cover, a container of ice cubes, water, and a lamp. Which part of the water cycle causes the water droplets to form on the glass cover?

• A. condensation

• B. evaporation

• C. precipitation

• D. runoff

Which of these best shows the correct sequence of processes that form sleet?

• A. rain falls ® freezes ® melts

• B. rain falls ® freezes ® stays frozen

• C. snow falls ® melts ® stays melted

• D. snow falls ® melts ® freezes again

What is the main process at work in the formation of clouds?

• A) precipitation

• B) rain

• C) condensation

• D) atmospheric compression

What is providing the energy for the cycle?

• A) sun

• B) rain

• C) gravity

• D) evaporation

What happens in order for water vapor to become liquid water or ice?

• A) cooling

• B) warming

• C) boiling

• D) no change in temperature

Evaporation changes a ______________________.

• A) gas to a liquid

• B) liquid to a solid

• C) liquid to a gas

• D) solid to a gas

How is a cloud formed?

• A) by the wind shifting the atmosphere

• B) by the combination of air and wind

• C) by rain combined with oxygen

• D) by the condensation of water vapor
