There in the Sky for Me
The Sun Makes All Our Weather
The sun causes all our weather because it
heats the earth unevenly. The contrast between the hot parts and the cold parts of the
earth turns our atmosphere into a powerful engine. The engine keeps cold and warm
air moving and makes changes in air pressure. Those air
pressure changes cause wind. The heat of the sun also helps moisture to rise and
form clouds, bringing rain, snow, or thunderstorms. So all the
changes in our weather come, at least indirectly from the sun. For more on the summer sun, go here.
1. Let the Sun Shine
Take a wet cloth and wipe it across a blackboard. Let the sun shine on part of the blackboard and watch the water evaporate. Does the water evaporate faster in the sun or in the shade?
Put some ice in the sun and some in the shade. Does it melt faster in the sunlight or in the shade?
