Exploring Earth's Water Distribution

What percentage of Earth's water is saltwater?

• 90%

• 75%

• 97%

• 50%

List the stages of the water cycle in order.

• Evaporation, Precipitation, Infiltration, Runoff, Melting

• Infiltration, Runoff, Evaporation, Condensation, Sublimation

• Condensation, Evaporation, Runoff, Precipitation, Freezing

• Evaporation, Condensation, Precipitation, Infiltration, Runoff

What process involves water vapor turning into liquid water?

• Sublimation

• Evaporation

• Precipitation

• Condensation

During which stage of the water cycle does precipitation occur?

• Evaporation

• Transpiration

• Infiltration

• Condensation

What is the term for water that flows over the ground into rivers and lakes?

• Aquifer discharge

• Surface runoff

• Groundwater flow

• Rainwater collection

Name two types of surface water bodies.

• Oceans

• Ponds

• Lakes, Rivers

• Streams

What role do oceans play in the water cycle?

• Oceans provide water for evaporation, which is essential for the water cycle.

• Oceans absorb all rainfall, preventing evaporation.

• Oceans only store water and do not participate in the water cycle.

• Oceans cool the atmosphere, reducing evaporation rates.

How does evaporation contribute to the water cycle?

• Evaporation only occurs in oceans and does not affect rivers.

• Evaporation cools the air and prevents precipitation.

• Evaporation contributes to the water cycle by transforming liquid water into vapor, which rises, cools, and eventually falls as precipitation.

• Evaporation turns vapor directly into ice without any cooling process.

What is groundwater and how does it relate to surface water?

• Surface water is always cleaner than groundwater.

• Groundwater is the water found in the atmosphere.

• Groundwater does not affect the water cycle.

• Groundwater is water stored underground, and it interacts with surface water through processes like seepage and recharge.
