If the earth were not tilted on its axis, what would be the results

If the earth weren't tilted, it would rotate like that as it revolved around the sun, and we wouldn't have seasons—only areas that were colder (near the poles) and warmer (near the Equator). But the earth is tilted, and that's why the seasons happen.

Explanation:

If the Earth weren't tilted on its axis, there would be no seasons. And humanity would suffer. The axis of rotation of the Earth is tilted at an angle of 23.5 degrees away from vertical, perpendicular to the plane of our planet's orbit around the sun. The tilt of the Earth's axis is important, in that it governs the warming strength of the sun's energy.
