How do we know the movement of air?
Air movement takes place in the troposphere. This is the lowest layer of the atmosphere. Air moves because of differences in heating. These differences create convection currents and winds.
What drives the movement of the water cycle?
The sun, which drives the water cycle, heats water in the oceans. Some of it evaporates as vapor into the air. Rising vapor cools and condenses into clouds. Cloud particles grow and fall out of the sky as precipitation.
What are two ways water returns to the atmosphere?
The water may be taken up by plants and returned to the atmosphere through processes like transpiration and photosynthesis. Water may also be returned to the atmosphere through the combustion of plants in fossil fuel.
