Brrr! It's cold here in Massachusetts! Im going to call Sarah in Australia, and see how shes holding up in the cold.
Hey Sarah! How are you ding down in Australia in the cold?
Hi Jim! What do you mean? It's not cold here in Australia. Don't you know how seasons work?
What do you mean? How can it be warm in Australia but cold in Massachusetts? I don't understand.
Well, it's because of the tilt of the earth. Right now I'm in the southern hemisphere, and the southern hemisphere is tilted towards the sun, making it summer. But you're in the Northern hemisphere, where its tilted away so its winter. The southern and Northern hemisphere seasons are always opposite.
Oh! Now I understand. But aren't there more parts to it than just the tilt of the earth?
