Water Cycle

How much salt water covers the earth?

• 55%
• 65%
• 75%
• 85%

The changes to water when it cycles the earth is called

• the moon cycle
• the sun cycle
• the water cycle
• the wind cycle

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

• condensation
• evaporation
• transpiration
• runoff

Water in lakes and rivers that does not contain salt-

• recycled water
• new water
• salt water
• fresh water

When water vapor s cooled and forms droplets-

• Condensation
• Evaportation
• Transpiration
• Run-off

After condensation, the droplets of water in the clouds fall to the earth in different forms

• precipitation 
• condensation
• evaporation 
• ground water

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

The sun's energy 

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

The land on earth covers approximately 

• 25%
• 50%
• 75%
