Its All Connected

The reason for the Earth's uneven heating is for the fact that it is tilted on an axis. Heat from the sun hits the Earth in different ways as the Earth tilts. I saw this by doing the experiment where we shined the flash light on the globe and observed how the light hit the globe. The Earth's rotation also affects the air. As the Earth spins the air gets moves around it which creates wind. We did an experiment with this where we put a drop of water on the center of disk and spun it. I observed the water then spun out in a swirl from the center to edge. This represents the coriolis effect and how the Earth rotates underneath the winds. There are also different types of winds. There are trade winds which go from east to west. Then there are westerlies which go from west to east. This is why it is quicker to fly from LA to New York than it is to fly from New York to LA. Wind patterns might change due to global warming because the Earth will now be heated even more than it was before.
