The Sun

-Sunshine starts all Weather

Do you know it is the sun that makes weather?

It heats some parts of our world more, some less. And with the Earth's rotation, unequal heating drives our weather. The sun provides energy by nuclear fusion. A fusion reaction fuses atoms together, creating other kinds of atoms and giving off energy.

Depending on the season and location, the sun bathes the Earth in widely varying amounts of energy. Land and water both absorb and give up heat. But land warms up and cools off more readily than water. Thus temperature varies from one region to another owing to their different geographical conditions.

The seasons bring the biggest swings between hot and cold. They are caused by the tilted Earth's year-long trip around the sun. The Earth's axis is tilted at an angle of 23.5 degrees. Because of its tilt, the sun is directly over the Tropic of Cancer when it is summer and the Tropic of Capricorn when it is winter. Different seasons are thus created.
