Seasonal Changes
Seasonal changes occur because the earth's axis is tilted compared to the sun. When the sun's rays hits the Earth it has to pass through more of the Earth atmosphere. When the sun's rays hit at a angle it spreads the light out. When it is summer in South America it is winter in North America that is because there is more sun hitting South America but since the Earth is tilted some of the light from the sun hits North America but since there's less then South America it makes winter days longer. Hope you enjoyed my blog.

i forgot to mention there are three things that make all the difference number one is that when you shine light at an angle it spreads it out more number two is that the suns rays has to pass through more of the earths atmosphere number three since the light hits at a angle it spreads the light out right that means there will be less light in in different parts of the world thus making the day longer.
