The Water Cycle

What’s inside

• Which process is primarily driven by solar energy in the water cycle?
• The water cycle has no true beginning or end because water continuously moves between Earth's reservoirs.
• What is percolation in the water cycle?
• For the same amount of water vapor, warmer air generally has a greater capacity to hold moisture than colder air.
• Which process directly forms cloud droplets when moist air cools to its dew point?
• Sublimation is the change of water vapor directly into ice without first becoming liquid water.
• Which process returns water vapor to the atmosphere from plant leaves?
• The oceans contain the largest amount of Earth's total water and are a major source of atmospheric water vapor.
