What angle would earth's tilt need to be in order for there to be no seasons on earth?

Answer 1

If the Earth had no axial tilt, the only seasons would be those caused by the difference in the Earth/Sun distance at perihelion and aphelion, which is an extremely minor factor (in fact, the Earth is closest to the Sun during winter in the northern hemisphere currently).

Answer 2

There would only be the one, continuous season. The seasons occur because at one stage of the year, we are further away than during the other part of the year. During June, July and August for America, America is closer to the sun than, say, Australia. In America's winter this is the reverse. If there was not tilt we would be the same distance away from the sun all the time and the weather would be the same.

Answer 3

If the axial "tilt" were greater or less than the current 23-and-change degrees, our seasons would be either more or less extreme than they are now.

The "tilt" is the angle between the axis of the Earth's spin and the perpendicular to the "ecliptic", which is the plane of the Earth's orbit around the Sun.

If there were no "tilt", then there would be no seasons, no variation in the times of sunrise or sunset, and probably less weather. The tropics would be hotter, the poles colder, and the "temperate" regions would be more boring.

Answer 4

To the Earth, nothing at all.

Our seasons are the result of axial tilt. If there were no winter, it would be because there was no axial tilt, and there wouldn't be any other seasons either.

Answer 5

The Earth is tilted at 23.4 or so degrees. At the equator there are very little in the way of seasons. The further north or south you go the greater the seasonal change. For no seasonal change the axis would have to be near or at zero degrees.

Answer 6

If the Earth's axis were perpendicular to the ecliptic plane, there would be no

seasons, and no change in the lengths of daylight and dark during the year.

The sun would always be overhead on the Equator and never anywhere else,

and the Arctic Circle, Antarctic Circle, and the Tropics of Cancer and Capricorn

would have no meaning.

Answer 7

If there was no seasons then all the nutrients would die out and the trees would die, as well. Then, there will be less and less oxygen each day.

Answer 8

If there were no seasons, the whole world would be a tropical climate, and none of the world's languages would have words for seasons. Apart from that, life would go on as normal.

Answer 9

No tilt = no seasons. Seasons are caused by the tilt of the Earth's axis.
