Can someone right an essay on seasons and how and why they change? i really need

             Many people wonder why we have the four seasons.These four seasons are Winter, Summer,Spring, and Fall.These seasons let us know things like what to wear, things to eat and places to go.Some people just think that's the way the world is,Winter is suppose to snow and be cold and in summer is suppose to be hot.
             Why do we have seasons and What causes it
             When the world rotates it tiltes onto different angles.Which means where ever the sun is it will be hotter and the least the sun, the more the wind.When the earth tilte, it tiltes on the earths axis which is an imagine line between the north and the south pole.When our part of the world is facing the sun it's day and when where facing away it's night.The earth circles around the sun year after year
              every day and night are equal length. 

Sorry i dont understand the question can you rephase it?
