HEY GUYS!!! Happy 11-11-11!!! The leaves are falling on this beautiful Autumn day! Well, actually, it's really cold today, and tonight it's finally gonna reach freezing. Ah Southern winters... So anyways, today were going to be talking about leaves, and I promise to stop talking like a weather girl now.
So, have you guys ever wondered why the leaves are green in the spring and summer, but then once September hits they start turning red/orange/yellow? This is because of Chlorophyll, a substance that helps plants make energy, or food. It makes the plant green!
Well, once summer ends and the days get shorter (because there is less sun in the fall), the chlorophyll does not get the amount of food required to survive, and it dies. So the green goes away, and the leaves natural colors begin to appear, the red/brown/yellow. The leaves also have to steal nutrients from the tree to survive, and once the tree doesn't have enough to share, the leaves slowly begin to die. Their stems get weak, and rain or wind make them fall to the ground. The leaves eventually rot into the ground.
Now for the next topic... SEASONS!!!

Okay so know how we have seasons? Well yeah, of course you do, but do you know why we have them? So let me tell you a story...
Once upon a time there were two best friends named Earth and Sun. Earth and Sun have been best friends for millions of years and get to spend everyday with each other. This is because the earth revolves around the sun and spins itself around at the same time. (Fun Fact: globes are titled to represent the tilt of the earth's axis, about 23.5 degrees)

So, the Sun and the Earth are moving together, and again, the earth is spinning above, while it spinning around the sun. This rotation takes about 365 days, or a year! Here's an animation.
So, since the earth is tilted, the sun can't hit ALL things at once. So, if the earth is hitting the northern hemisphere, the days are long and hot. But at the same time: what about the southern hemisphere?(In case your wondering, the north hemp is the top half of the equator, and the southern is the bottom half) It's getting almost no sun at all. In fact, there are days in the summer and the winter where it is 24 hrs light.darkness. Wow!
So it could be Winter here and Summer in Australia! It's weird to think about sometimes, I know! SuperSaraSuperBye! Click on the links below!
