Hey you are probably wondering what are we going to learn about.I know my Title does not help at all. We are going to learn about Seasons and what in the world makes leaves change colors.
First,seasons are caused by the tilting of the Earth.The Earth is split into 2 sections the north and South hemisphere and is tilted about 23.5 degrees.Globes are tilted because the Earth is too.The Earth spins on it's axis every day.One full rotation means one day.The axis are imaginary lines that go from the North pole to the South pole.
While the Earth spins around on its' axis it is also orbiting around the Sun.Since it is tilted the hemispheres have different angles on how the sun hits them.If it is winter in the northern hemisphere it is summer in the southern hemisphere.
The leaves change color because the sun stays out for a shorter .In autumn the leaves turn different colors because the clorophyll goes away and the other colors are now visible.The clorophyll is what makes the leaves green.
