What would you like to do?
All places would have greater extremes in temperature from warmer in the summer to cooler in the winter then it is now. It would affect the daylight received on any part…icular day compared to the current situation and more places torward the poles would have more days of darkness and days without darkness each year compared to current.
Good question! relative to the plane of its orbit around the sun!
This reads like a homework problem. . .=) There wouldn't be any seasons. They occur because of the tilt of the earth. But i don't want to do your homework for you--…consider this a hint.
23.5 is - or very close - the actual tilt of the Earth. So as long as that is the case, nothing particular happens due to that.
The seasons would not have as much variation in temperature. But the temperatures at various latitudes would be more severe than what we experience now. Hot climates would be …hotter and cold climates would be colder, with less variation from minimum to maximum temperatures in the region. The Earth's inclination (tilt) is 23.5°. Examine the following explanation I have for extreme situations, one with 35°, one with 0° and one with 90° inclination. If the Earth's inclination were 35° the seasons would be more severe. Areas around the equator would be the best places to live. In the latitudes father away from the equator, colder winters would be the most prominent change. Our current arctic and antarctic circle latitudes are at about 66½°. This change would drop them to 55° latitude. A significant portion of he world would be in a very hard environment to live in, but overall the earth would be habitable. There are two other conditions that would have extreme ramifications, if the Earth had no tilt and if it was tilted with a pole pointing towards the sun continuously. With an inclination of 0°, the seasons would not change. The equatorial region would probably not be habitable. The temperate zones would be much narrower. The arctic regions would as the equatorial region be much more severe in its temperature range. Without seasonal change, the equatorial region would get to a very high temperature on a constant basis and the arctic regions would become much bigger and settle into a constant subfreezing condition. That would leave us with a much more narrow temperate zone. I would say that the easily habitable regions of the planet would lie between 35° and 55° latitudes, north and south, which if you look at a world map, cuts out about 70% of the currently habitable space. The last scenario is the worst of all. If the rotational axis, lets say the north pole of the earth was pointed directly at the sun (90° inclination), we would be in a situation in which only one side of the planet ever gets sunlight. The other side side, the dark side would be dead due to the extreme cold. The side that faces the sun would have large area that would be perpetually hot, too hot to sustain life. This would leave only a small strip near the equator where the sun supplies enough heat to keep the area habitable. In this area, the sun would always be low in the sky, never setting and never rising. It would be a perpetual sunrise/sunset. Meanwhile, at the pole, which now faces the sun in constant noontime, the heat is tremendous. The Arctic Ocean below would provide water for a massive storm that would be everlasting. This situation would also be true if the Earth was gravitationally locked with one side facing the sun, like the moon is with the Earth.
your season would entirely depend on where you live, at the equator, less of the sun, the further north or south you went, the more sun, colder and at the poles, you would hav…e 24/7 sunlight at the poles, so basically if you had no tilt, life would evolve according to the environment of where it lived. :)
Earths axis of rotation is tilted at an angle of 23.5 degreeswhat is one change you would see on earth if its axis was not tilted?
There would be many changes. First there would be only one season all the time with minor differences when Earth is at perihelion and aphelion. The time of sunrise and sunset …would not change and at the equator there would be 12h or night and day.
The arctic circle would be nearer the equator. Summers and winters would be longer and more severe.
What might be the effect on seasons if the earths orbit became more elliptical and at the same time the angle of the tilt of Earth's axis increased?
A lot would depend on "How much?" additional tilt and eccentricity of the orbit. The Earth's axis of rotation is currently 23 and change degrees "tilted" to the ecliptic, the …plane of the Earth's orbit around the Sun. If the angle increased to 30 degrees, it probably wouldn't make all THAT much difference; the temperate zones would be somewhat expanded while the polar weather would become a little more extreme. Earth's orbit around the Sun is an ellipse, but with only about 3% eccentricity; it's nearly circular. The Earth is at perihelion - closest to the Sun - on January 4 (plus or minus a day, depending on the cycle of leap years) and is at aphelion around July 2. The difference in the distance is only about a million miles or so. If the Earth's orbit were made more eccentric, swinging closer to the sun and farther away, it could easily render the Earth uninhabitable. Over the course of the last 3 million years or so, we've had wild swings between warm weather and ice ages. (We're currently near the peak of one of the warm periods.) Scientists studying human DNA and evolution have calculated that during the last ice age (with a push from a whopping HUGE volcanic eruption!) the human population was down to perhaps 100 breeding pairs of humans. We very nearly became extinct, 70,000 years ago. An extended winter caused by moving 20 or so million miles away from the Sun could easily finish the job.
Seeing as it is currently some 23.4 degrees, the seasons with an axial tilt of only 13 would be somewhat milder. The differences between summer and winter months would be less… extreme.
Further away from the equator, they'd get more pronounced. A bigger area would never get night during summer, and never day during winter.
It would receive more direct Sun in the summer.
The Earth's seasons would be more severe, and the north and south pole would shift a little
The seasons would intensify, and the Summer would be hotter, and the Winter be colder. This would make for a completely different environment, since the change would be larger… between seasons. Just this tiny change would probably make thousands of animals extinct. It would change farming. It would make weather more intense. If this happened suddenly it would probably be cataclysmic.
The short answer is yes. However, at that point of tilt of no return the earth will continue to tilt 360 deg. The sun will rise in the west and set in the east. the next year …it will again rise in the east and set in the west. this exchange will continue forever.
Would seasonal variations on earth be significantly changed if the angle of tilt of earth's axis changed?
Yes very much so
Even a small change in tilt of the earth's axis would have a profound change in the earth. It would change the length and temperature of our days and seasons. Depending on… the angle of tilt, it would melt the polar ice caps or it would lower the earth's temperature causing polar ice caps to increase in size. This in turn would increase or decrease the level of water in the oceans, all of which would dramatically influence our weather. Some organisms would go extinct because they could no longer survive in new environment; and others would go extinct because they depend for survival on the organisms that have gone extinct. Many plants would become extinct as well, affecting the food supply of the entire planet and every living soul. It is quite possible all life as we know it could cease to exist if the earth's tilt were to change. It is also quite possible that new life forms could come into being that could have a positive effect or a disastrous effect on earth's systems. Even a very "small" change in world tilt would have profound implications.
