• 2.5%

• 3%

• 30%

• 68%

Multiple Choice

What percentage of the freshwater on Earth is surface water?

• 1.2%

• 2.5%

• 30%

• 68%

Multiple Choice

What is another term for the Water Cycle?

• Hydrogen cycle

• Hydrological Cycle

• Hydrosphere Cycle

Multiple Choice

What powers the water cycle?

• The Sun

• The Moon

• Heat from Inner Earth

Multiple Choice

Which of the following is associated with condensation?

• Liquid water changing into solid water

• Solid water changing into liquid water

• Liquid water changing into water vapor

• Water vapor changing into liquid water

Multiple Choice

How does water become groundwater?

• Soaks into the ground through infiltration

• Rises into the ground from inner Earth

• It flows into the ground from the Ocean

Multiple Choice

What happens to water that does not infiltrate into the ground?

• It evaporates into the hydrosphere

• It flows downhill as surface runoff

• It precipitates into the atmosphere

Multiple Choice

Water in large lakes and oceans comes from

• only the surface

• only groundwater

• both surface and groundwater

Thunderstorms

Multiple Choice

Which of the following is NOT an ingredient needed for the formation of a thunderstorm?

• Wind

• Moisture

• Lift

• Unstable air mass

Multiple Choice

Why does Florida have more thunderstorms than any other state?

• It has a lower elevation than the other states

• It is surrounded on three sides by warm ocean water

• There is more static electricity in the air in Florida

Multiple Choice

What makes a parcel of air unstable?

• It continues to rise or sink

• It rises or sinks for only a short time period

• It never rises when it is hot

• It never sinks when it is cold

Multiple Choice

What type of clouds are associated with thunderstorms?

• Cumulus

• Cirrus

• Stratus

• Cumulonimbus

Multiple Choice

Why are there frequent thunderstorms in the mountains?

• Because the warm air just sits at the base of the mountain and builds up even more heat

• Because the change in elevation provides even more lift to already warm air

Multiple Choice

What is the rain shadow effect?

• Shadows that can be seen when it rains

• When more rain is produced in the shadow of a mountain

• When all the moisture in the air has already been released on one side of the mountain and only dry air descends on the other sides.

Multiple Choice

What type of front is usually associated with thunderstorms?

• Warm fronts

• Cold fronts

• Stationary fronts

• Occluded fronts

Multiple Choice

When are thunderstorms more likely to occur?

• On a warm, sunny day

• On a cold, drizzly day

Multiple Choice

During which stage are thunderstorms the most dangerous?

• Towering Cumulus Stage

• Mature Stage

• Dissipating Stage

Multiple Choice

Which of the following statements is true?

• Thunderstorms usually result from one storm cloud.

• Thunderstorms usually result from multiple storm clouds that merge together.

Multiple Choice

Which of the following statements is true?

• Lightning strikes originate from both the clouds and the ground.

• Lightning strikes originate only in the clouds

• Lightning strikes originate from the air and the clouds.

Multiple Choice

Which of the following is responsible for creating lightning?

• High temperatures in the clouds

• Low temperatures in the clouds

• Static electricity in the clouds

Multiple Choice

What creates thunder?

• The collision of water molecules in the cloud

• The rapid expansion and contraction of air molecules

• Lightning striking nearby objects on the ground
