Change of season caused by rotation of earth or revolution of earth or revolution of sun?

Answer 1

The Sun is not the celestial body that moves in the sky. Earth orbits, or spins, around the Sun in 24 hours. As we on the Earth orbiting the Sun rotate around the Sun, the Sun's position seems to be moving when it is actually perfectly still. Think of it like this: if you are facing an object, try turning a little bit; doesn;t it seem like the object is moving, too? The object was the Sun while you were Earth.

Answer 2

Earth's axis is tilted 23.44°.

This has the effect of making the sun low on the horizon during winter, and higher during the summer.

Answer 3

because the earth is moving round

REVISION

The Earth rotates around the Sun, this gives the illusion that the Sun moves across the sky. So, the Sun isn't really moving, we are.

Answer 4

At the equinox day and night are of the same length all over the world because the Sun is in the plane of the Earth's equator, and that happens on March 21 and September 22 each year.

At other times the Sun is above or below the Equator, and day and night have unequal lengths.

Answer 5

The Earth spins on an axis and also orbits round the Sun.........The Earth on the

axis produces night and day as it spins away from the sun for about 12 hours.

As the Earth orbits it get nearer and closer to the sun so producing seasons and

temperature.

Another Answer

"The Earth spins on its axis of rotation and also orbits around the Sun". The axis is tilted relative to the sun/Earth plane. Earths equatorial plane is tilted off the sun/Earth plane because of the axis of rotation.

It takes the Earth ~24 hours to make one complete revolution on the axis. This produces night and day as any single point on the surface of the Earth rotates toward and away from the sun for about 12 hours each.

The Earth's varying distance from the sun has nothing to do with seasons or temperature. Although the orbit of Earth around the sun is elliptical, the distance it varies isn't enough to create much difference in our temperature. If our orbit drew a flatter and longer ellipse, this would indeed complicate our ecosystem.

The Earth takes approximately 365.25 days to orbit the sun. During one half of the orbit, more of the northern hemisphere is exposed to the sun because of our axis of rotation. This is when it is summer in the northern hemisphere and winter in the Southern Hemisphere. During the other half of our solar orbit, more of the southern hemisphere is exposed to the sun. This is when it is winter in the northern hemisphere and summer in the southern hemisphere.

Answer 6

The seasons are due to the motion of the Earth around the Sun. So, it may not be surprising that the Sun's position in the sky changes over seasons, due to the motion of the Earth around the Sun. The explanation is simple. All stars in the sky are moving, but the distant stars are so far away that we cannot detect appreciable motion (even when the Earth moves around the Sun). As a result, the positions of distant stars in the sky are fixed. At any single moment the Sun can be projected as a dot onto the night sky by extending the line that connects the Earth and the Sun (the line of sight) all the way to the sky. As the Earth orbits around the sun the line of sight changes direction and since the distant stars are fixed in the sky, the position of the Sun with respect to the distant stars changes.

The main factor that changes the Sun's position in the sky is that the earth's axis of rotation is tilted. This means that the sun is higher above the horizon in the summer months than in the winter.

Answer 7

The Earth is constantly revolving around the Sun, so the position we see the Sun at changes continuously.

Answer 8

because the earth is tilted 23.5 degrees towards the north star, so we have two equinoxes in the spring and fall

Answer 9

Change of seasons is caused by the tilt of the earth's axis.

Answer 10

Tilt of the earth, the rotation, and revolution of said planet
