A lightning bolt is created from the ground up and also down from the sky. Negative charges from a thunderstorm slowly lower to the ground, while positive charges rise from the ground or an object toward the sky. When th... More »

Differences in the amount of sunlight hitting the earth cause the three main climate zones. However, weather varies within these zones. An area in the temperate zone, for example, can be warmer than an area in the tropic... More »
