Well....when we talk about weather, unequal might be better. Think about a world where all the weather was equal...
If the Earth had equal heating there would only be TWO atmospheric cells. At the equator the air would rise and below the equator the air would be pressed to the surface of the Earth because of gravity. This would cause high pressure. The only storms on Earth would be around the equator where the warm air met the cooled air...
Our weather would be totally different than what we know now. Because the Earth spins on a tilted axis, the Sun heats the Earth unequally. This causes wind and ocean circulation to spread out the heat unevenly across the Earth. Which is a good thing. Unequal heating pushes air masses across the Earth in bands. This brings weather all the way to the poles.
Because of unequal heating we have polar regions, tropical regions, and temperate regions. We have deserts and rain forests. We have warm places and cold places. The diversity of our climate has allowed hundreds of thousands of plants, animals, microorganisms and bacteria to flourish on Earth.
That's so cool, I didn't know know the earth had polar cells before this lesson.
ReplyDeleteI really want to go to somewhere tropical.
ReplyDeleteSo do we all.
DeleteThat is cool that it causes so many different climits.
ReplyDeleteThose winds make the Earth look like a giant bouncy ball, or a giant weirdly shaped beach ball
ReplyDeleteFree the Earth! Make heating equal!
