What process describes liquid water transforming into a gaseous state due to gaining energy?

• Condensation

• Precipitation

• Evaporation

• Percolation

When water vapor rises and cools in the atmosphere, what process leads to the formation of clouds?

• Sublimation

• Evaporation

• Condensation

• Infiltration

What is another name for percolation? (Water moving down into the soil).

• Condensation
• Evaporation
• Transpiration
• Infiltration

After precipitation falls on land, which two pathways can the water primarily follow?

• It can only evaporate or be transported by wind.

• It can become surface runoff or infiltrate into the soil.

• It can form ice crystals or remain as liquid droplets.

• It can be taken up by plants or condense into clouds.

What is runoff?

• Runoff is the collection of water in underground aquifers.
• Runoff is the flow of water, usually from rain, that moves across the land surface and into water bodies.
• Runoff refers to the absorption of water by plants.
• Runoff is the process of water evaporating from the soil.

What process is basically evaporation, but off of the leaves of plants?

• Transpiration
• Photosynthesis
• Evaporation

• Condensation

What process describes solid ice turning directly into water vapor?

• Evaporation

• Condensation

• Sublimation

• Precipitation

• 68.9%

• 2.5%

• 30.8%

Where is the largest portion of Earth's freshwater stored?

• Lakes and rivers

• Groundwater

• Glaciers and permanent snow cover

• Atmosphere
