What would seasons be like if earth's axis were tilted at a higher angle more than 23.5?
What would the season be like in the Northern and Southern hemispheres if the earth's axis weren't tilted?
If the Earth's axis were not tilted at least a little, there would be no seasons; the climate would be pretty constant year around, and the weather would be entirely dependen…t on the latitude.
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.
What would be the effect on earths seasons if the axis were tilted at 28.5 degrees instead of 23.5 degrees?
They would be more extreme: winters would be colder and summers would be hotter. The temperate zones would contract, and the polar and tropical zones would expand.
How would the general circulation of air appear in summer and winter if the earth were tilted on its axis at an angle of 45 degrees instead of 23.5 degrees?
The ITCZ would shift further north in the northern summer and further south in the northern winter. Similarly the subtropical highs and polar fronts would shift further fr…om the equator during the summer and closer to the equator in the winter in both hemispheres than is now the case.
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.
Every thing would be the same. The seasons, and the order of the seasons, would be the same. The only difference would be that the seasons would be 1/2 year out of phase fro…m their current timing, meaning that when it is winter with a normal axis tilt, it would be summer with a reverse axis tilt.
The seasons would be more extreme: winter would be colder and summer would be hotter.
The seasons would be more pronounced, i.e. the summers would be hotter, and the winters colder. The incidence of EM radiation would not change but its distribution would, muc…h of the present ice caps would melt and shift and the temperature difference between summer and winter would be far more pronounced.
earths axis is responsible for seasons because if its tilted toward the sun then it would be summer in the northern hemisphere and winter in the southern now if it was tilted …away from the sun then it would be winter in the northern hemisphere and summer in the southern hemisphere
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. :)
What if the earths axis of rotation were tilted at a different angle. also what would the seasons be like if earths axis was a 0 degrees and b 45 degrees?
Earth's axis has a tilt of 23.5 degrees; this is what causes seasons. 0 degrees: practically no seasons (there would be minor changes due to a varying distance from the Sun). …45 degrees: seasons would be much more pronounced.
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.
Actually, the axial tilt is currently 23.44 deg and decreasing.The axial tilt is in a continuous cycle between 22.1 and 24.5 degon a 41,000 year cycle, one of the Milankovich …cycles known asobliquity. . Well, the seasons would be different. As the tilt of the axisdecreases, the changes in seasons would be less and less noticeableuntil there would be no change at all at a tilt of zero degrees.Animals and plants who depend on different climates and/or seasonsfor mating/hibernating reasons might also be doomed... . A more interesting question would be what would the climate belike when the tilt is at any given angle. . Zero degrees - no change . 5 degrees - small change, midnight sun only very close to thepoles . 10 degrees up to about 25 degrees - similar to what we havetoday . 25 to 35 degrees - Interesting. Let's see - more extreme summersand winters. . Longer summer days, shorter winter days in the higher latitudes.The Arctic and Antarctic circle would be as far as 55 degreesnorth/south, which would put half of Scotland, to say nothing ofScandinavia, a great deal of Russia, the Baltic Republics, Canada,and all of Alaska except the southern tip, in darkness in lateDecember and 24-hr light in June. The opposite can be said aboutthe southern tip of South America. New Zealand would have anextremely short day (how short?) in June, and likely have frigidweather in June, similar to today's Finland in December. . The Tropic of Cancer/Capricorn would be at 35 north/south, whichwould give places like Syndey, Aukland, Buenos Aires, Cape Town aswell as Tokyo, Oklahoma City, Los Angeles, a sweltering summertimeclimate simliar to Havana, Cuba, Florida today. We could go on andon. . 35 to 45 degrees - This is even more interesting. Imagine thepoles being temperate and the equator being frigid. Do acalculation of the average annual solar energy that impinges upon agiven surface at a given latitude assuming a tilt of 45 degrees.Then do the same calculation for each season of the year. . 45 to 90 degrees - More interesting even yet. Imagine the sunnever setting at the north pole, being directly above.
It would receive more direct Sun in the summer.
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.
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 Earth's axis IS tilted (by about 23.5 degrees from the plane of its orbit), and that is what causes the seasons. If it were not tilted, there would be no seasons. If i…t were tilted more, the seasons would be more extreme. Without any tilt, the equatorial regions would be generally hotter, and the poles would both have permanent daylight, although with the Sun always exactly on the horizon. Conversely, they would be colder overall, as would the higher latitudes except where air currents brought in warmer air. If it were tilted over completely (similar to the tilt of Uranus), the day and year would be the same length (1/2 of the year), and the conditions very unfavorable for life as we know it.
