This is because Aristotle believed that purposive final causes guided all natural processes. He classified organism according to their traits, but there was many problems of Aristotle’s limited classification because some organisms didn’t fit the group.
For example, he put birds, bats, and flying insects in the same classification group because of their ability to fly, but today we know that they have little in common. He also distinguished animals with blood and animals without blood.
Hot air always rises from the equator. As this air climbs higher in the sky, it cools. Cool air can hold less water than warm air. This means that as the air cools, clouds form that release most of the water they hold. Because the cooling air is above the equator, the moisture rains back down on the tropics.
