What is another term for the water cycle?

• Infiltration cycle

• Hydrological cycle

• Precipitation cycle

• Brackish cycle

Forms of precipitation are-

• only sleet and snow
• rain, sleet, hail, and snow
• only dew and rain 
• only snow and rain

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

What happens to particles when they are heated?

• They speed up and spread out
• They slow down and compress
• They stop moving
• They move closer together and speed up

When water is heated in the ocean by the sun and turns into water vapor

• condensation
• evaporation
• transpiration
• runoff

The sun's energy 

• changes daily
• heats the ocean before evaporation
• directly causes evaportation

When water turns into a gas

• condensation 
• evaporation
• precipitation

What is evaporation?

• 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.

More evaporation happens at temperatures that are…

• warmer

• cooler

• the rate does not depend on temperature

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
