can u tell me about how rotation & revolution affect the earths four seasons? thanks?

Answer 1

Earth's rotation does not affect season. The rotation of the earth causes day and night. In addition to rotating on its axis, Earth travels around the sun. Revolution is the movement of one object around another. One complete revolution of Earth around the sun is called a year. Earth's orbit is not quite circular. It is a slightly elongated circle.

Sunlight hits Earth's surface most directly near the equator. Near the poles, sunlight arrives at a steep angle. As a result, it is spread out over a greater area. That is why it is warmer near the equator than near the poles.

Earth has seasons because its axis is tilted as it revolves around the sun. As Earth revolves around the sun, the north end of its axis is tilted away from the sun for part of the year and toward the sun for part of the year.

Summer and Winter are caused by Earth's tilt as it revolves around the sun. The change in seasons is not caused by changes in Earth's distance from the sun. In fact, Earth is farthest from the sun when it is summer in the Northern Hemisphere

Answer 2

The distance has nothing to do with the seasons its the axis of how the earth is tilted toward or away from the sun on its orbit, during the summer (norther hemisphere) the planet is tilted down (towards) and in the winter it is tilted up (away). tho the planet doesn't tilt at all its the rotation of the earths orbit that makes it seem like its tilting.
As the earth rotates around the sun its axis never changes but the rotation slowly changes the seasons as the earth orbits the sun.
spring and fall are called the equinox (equal amount of daylight and night) and winter (less daylight) and summer(most daylight) are solstices. I have also heard the sun is closer to the earth during the southern hemisphere's summer and that is why the southern hemisphere doesn't have any Sub-Arctic regions.
I hope that helps a little.

Answer 3

Rotation only affects our day-night cycle. The fact that the Earth tilts on its axis makes is so that as the earth revolves around ( or orbits) the Sun, the directness of the Sun's rays varies, thus varying the heat and thus the seasons. Because the Earth is spherical, this tilt also explains the difference in the length of a day.

Answer 4

Well done, bluecuriosity and convinced.

So, many people are under the misconception that the seasons are caused by the Earth being various distances from the sun. That is totally fallacious.

As blue points out, it is purely the angle of the sun. And why can't people work this out - after all, the same effect is seen daily. It gets hotter when the sun gets higher in the sky (assuming the current weather system does not change).

There is one other factor wiith the seasons. You get a longer daylight in summer - more time to warm up, and less night to cool down.

But mainly it is the height of the sun affecting the intensity of radiation received.

Answer 5

Listen closely, here's how it is....

Rotation on earth axis- only affects day and night

Revolution around the sun - would do nothing IF the axis of ROTATION was not TILTED, very important to remember.

The Earth's tilted axis is always the same as we travel around
the sun (axis doesn't rotate). The difference between summer
and winter for a hemisphere is determined by what ANGLE
you recieve sunlight through the course of the day.

Experiment:
Observe the sun at NOON on the hottest day of summer and note that the sun is HIGH up overhead (shadows only below you).
Observe the sun at NOON on the coldest day of winter and note that the sun is LOWER on the horizon (longer shadows).

Answer 6

As pointed out by many persons above, it is the tilt of the earth's axis(with respect to the plane of revolution around the sun) that causes the seasons;nothing else.

Answer 7

The Earth does not move around the sun in a perfect circle. It goes in more of and oval shape around the Sun. This causes different seasons. When the Earth gets the closest to the Sun, it turns to Summer, when it gets further away, it becomes winter. The middle stages are Spring and Fall.

Answer 8

Do not pay attention to 6th Class students answering this.
The Sun gets full throttle opened when it's summer.
Them refrigerator on the moon opens its doors when its winter.
The Clouds come in between when it's fall.

All these things can besaid by6 Class dropouts.
It's the axial tilt coz ing the seasons. Hunt the net to get more confused and untimatly accept that all 6th class drop outs are miserable and lost.
