Question

I know Earth's rotation affects the seasons, but does Earth's revolution around the sun affect the seasons?

Answer 1

The 23.5 degree tilt of the Earth's axis as it revolves around the sun is the cause of the seasons. All parts of the Earth receive equal amounts of sun light over the course of a year, but because of the tilt the suns rays are diluted over a wider area at parts of the Earth's surface at different seasons of the year because of the angle they hit the surface, this condition cause the polar regions to experience twenty four hours of sunlight for the winter days of the arctic months, and twenty four hours of darkness in the Antarctic. The rotation of the Earth determines day and night.

Answer 2

This is an example of a strange phenomenon on Wacko! Answers, whereby a horde of people giving completely wrong replies appears suddenly for one question only, and then disappear into cyberspace again. Often accompanied by thumbs-downs for all the more correct answers. Then the right answers come to bring equilibrium again.

The rotation of the Earth is what gives us day and night, as the Earth spins around its own axis. Nothing to do with seasons.

The revolution around the sun gives us the seasons. Because the Earth is tilted 23.5 degrees in relation to the sun, for part of the year, one half of the Earth is tilted more towards the sun than the other half. Because of this, the part of the Earth towards the sun gets more direct sunlight, for longer days, and therefore heats up more. This is what we call summer The other half is in winter. Then the opposite happens half a revolution (or half a year) later.

The orbit is slightly elliptical, but this has little effect. The northern summer occurs when the Earth happens to be further away from the sun.

Answer 3

The earths rotation doesn't effect the seasons. The Earths revolution around the sun does effects the seasons. The earth is tilted. So when the earth's northern hemisphere is tilted away from the sun it is winter. When the earth is on the opposite side of it revolutioin the northern hemisphere is facing the sun and it is summer. One weird little fact is the earth is closest to the sun during the winter.

Answer 4

Its actually a combination of the two which affects the seasons....

It has nothing to do with being farther away from the sun! The north and southern hemispheres have opposite seasons (Its winter in the US and Europe while its summer in south america, africa, and australia).

The reason for this is because the earth rotates on a tilted axis relative to its axis of orbit around the sun. This causes the day/night ratio to change over the course of the year. If its day time for 16 hours and then dark for only 8, its going to be much warmer than if its daytime for 8 hours and then dark for 16. It doesnt shift quite that much ;) You get the idea though.

Answer 5

Sorry, you've got that the wrong way round, The earth's rotation just creates day and night. The seasons are caused by the tilt of the earth's rotational axis as it orbits the sun. There is also a small effect caused by the fact that the earth's orbit is not exactly circular. This leads to the northern hemisphere's summer being when we're furthest from the sun and the winter when we're nearer. So the northern summers are cooler and longer and the winters warmer and shorter than the southern. Equally the southern summers are hotter and shorter and the winters colder and longer.

Answer 6

Earth's rotation actually has little to do with the seasons. Seasons are caused by Earth's axial tilt of 23 1/2 degrees. During part of the year (northern hemisphere summer) the north pole tilts toward the sun, and the south pole away from it. 6 months later, it is tilting away from the sun, and the south pole tilts toward it. This causes the northern hemisphere to receive very direct rays from the sun in northern summer, and very indirect in northern winter. If the Earth's axis had no tilt, we would not experience seasons. Climate would stay pretty much the same year round.

Answer 7

Hate to say this, but Earth's rotation gives us day and night. The Earth rotates on its own axis every 24 hours which is why one day is 24 hours long.
The Earth takes 365 1/4 days to go round the sun and its axis is tilted. When the Northern Hemisphere is tilted towards the sun, we have Summer, and the Southern hemisphere have Winter. when the Northern Hemisphere is tilted away the reverse occurs. Spring and Autumn are the phases between the two. This is why daylight hours are longer in summer. The 2 Equinoxes are the days when day and night are of equal length.(September and March). Hope this helps.

Answer 8

Earth's rotation has nothing to do with seasons. It only has to do with the cycle of day and night, which is extraordinarily stable. Earth's tilted axis in relation to its orbit around the Sun is what causes seasons. As Earth orbits around the Sun, the northern and southern hemispheres alternately get progressively more and less direct sunlight, which causes seasons. Because the orbit of Earth around the Sun is nearly circular, there isn't much if any effect on our seasons.

Answer 9

It's not really our rotation - but our *angle* of rotation.

Earth is tilted 23.5 degrees from our angle of rotation. So, this means that on June 21st, the northern hemisphere is tilted the maximum amount toward the sun, and we have very long days. (Anywhere within the Arctic circle has 24 hours of sun that day, and less amount as you go south.) During the spring & fall equinox, our day is exactly 12 hours, the same as our night. Then, during the winter solstice, our day is the shortest - and we receive much less sunlight than we did on the first day of summer. It's the tilt - and the amount of time the sun shines on our hemisphere, that determines the seasons.

Answer 10

No, it's not Earth's rotation on its axis that affects the seasons. Our seasons are due strictly to Earth's 23-degree tilt on its axis of rotation along with our orbit around the sun.
