How would seasons be different if the earth did not tilt on its axis?

Answer 1

There would be no seasons. If the earth rotated on an axis "straight up and down," every region of the earth would get the same exposure to sun. The northern and southern regions would always be temperate, the equator would always be hot, and the poles would always be, well, polar. The real difference is that the earth's tilt constantly changes: The earth precesses in its axis. In northern summer, the north pole tilts more toward the sun so that that region gets warmer, then in winter, the axis tilts back so that the north gets less sun.

Answer 2

Seasonal change would be far less dramatic, but not non-existant like others have said.

The planet's revolution around the sun is slightly further out on one side than the other, this is why the South Pole tends to be a little colder than the North Pole.

The whole planet would experince a mild cool down during the time that is regularly Winter in the Southern Hemisphere and Summer in the Northern.

The the implications of no longer having seasons would drasticly change weather, migration and pretator/prey balances, insect life and everything based off it and many, many other vast and unpredictable changes, that would likely be catastropic to the eco-system.

Answer 3

You would dramatically reduce the seasons especially the changing lenght of daylight.

HOWEVER:
Since the Earth Orbit around the sun is not a perfect circle rather eliptical. There would still be a SLIGHT seasonal effect as the earth travel slightly closer and farther from the sun during its orbit

There is also a tilt to the orbit as well which would also give a seasonal effect.

Answer 4

Seasons, as we now know them and speak of them, would not exist. There would be a modest change in climate over the course of the year, because the Earth's distance from the Sun varies, but the effect would not be large. You can tell this for yourself---------the Earth is nearest the Sun in the Northern Hemisphere's winter and furthest during the N. hemisphere's summer. The seasons have a more extreme swing in the Southern hemisphere for this reason, but again, the effect is small.

Answer 5

he seasons result from the Earth's axis being tilted to its orbital plane; it deviates by an angle of approximately 23.5 degrees of arc. Thus, at any given time during the summer or winter, one part of the planet is more directly exposed to the rays of the Sun (see Fig. 1). This exposure alternates as the Earth revolves in its orbit. At any given time, regardless of season, the northern and southern hemispheres experience opposite seasons (see Fig. 2 and Month ranges of seasons (below) and Effect of sun angle on climate
If there is no tilt on earth's axis, there is no season.
We may, however,have oceanic currents, and winds to adjust the weather, the distant from the sun also helps.
Is this your project ?

Answer 6

There would be no seasons at all, because earth's axial tilt brings different amounts of sunlight to the same areas at different times of the year.

There may be a very slight change since earth's distance to the sun varies from 91.5 million miles in January to 94.5 million in July (averaging 93 million), and if this distance were noticeable January would be wamer than July in the northern hemisphere.

Answer 7

The earth has a magnetic field, that hold the earth at its present axis. Scientist say in a few hundred years, this magnetic field will shift thus throwing the earth out of its alignment. This magnetic misalignment will cause earth quakes, title-waves etc. Some parts of the earth that where above water will now be somewhat submerged.
So I'm sure this will effect the weather a great deal.

Answer 8

There are a few simple explanations:

Because parts of the world would not be as close or as far away as they should be, the seasons would vary, but only slightly.

Summer would always be near the equator, and winter near the poles, but it would be fall consistently in the northern hemisphere between the pole and equator, and it would be fall in the southern hemisphere between the equator and the pole.

The temperature changes however would be extremely destructive to how our earth is formed today.

Answer 9

Yeah...seasons would be a permanent cycle of hot at the equator, and colder than now at the poles. The point closest to our sun, gets the hottest.
We could survive, but it would take a good long while to adjust.

Answer 10

There would be no seasons. It would be summer near the equator and winter near the poles. The rest would be like fall and spring.
