Water Cycle

When water vapor is cooled and forms droplets of liquid water

• Condensation

• Evaporation

• Transpiration

• Runoff

Precipitation occurs because 

• the droplets evaporate in the air
• the droplets are too light for the air to hold
• the droplets are too heavy for the air to hold

When water turns into a gas

• condensation 
• evaporation
• precipitation

What is condensation?

• The part of the water cycle when the sun heats up water, turning it from a liquid into water vapor or steam. It rises from the ground into the air.
• The part of the water cycle when the water vapor in the air gets cold. The water turns back into a liquid and forms clouds.
• The part of the water cycle when clouds get heavy and can no longer hold the liquid water. This causes the water to fall from the sky to the earth as rain, snow, sleet, or hail.

What is water that flows in rivers and streams into the oceans and lakes?

• evaporating
• condensing
• precipitating
• runoff

On which kind of day would you expect the most evaporation from the surface of a pond?

• cold, rainy
• cold, sunny
• warm, rainy
• warm, sunny

____________________ is the process by which water on the ground surface enters the soil.

• Infiltration

• Percolation

• Deposition

• Condensation

__________________ is the process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapor and is released to the atmosphere. It is essentially evaporation of water from plant leaves.

• Transpiration

• Percolation

• Infiltration

• Plant Uptake

Water that flows across the land and enters rivers and streams. It eventually flows into lakes and the ocean.

• Transpiration

• Surface Runoff

• Deposition

• Precipitation
