are seasons caused by closeness to the sun?

Question

are seasons caused by the closeness to the sun?

if true:
why are different places on Earth (in the north and south) the same temp. sometimes?

if false:

what does cause seasons?

Answer 1

>are seasons caused by closeness to the sun?

No.

>if false:
>what does cause seasons?

A tilt in the Earth's axis. The Earth's axis (that is, the line it spins around to make days) is not directly perpendicular to the plane of its orbit, and it stays with the same offset orientation no matter where it is in its orbit. So during one part of the year, the top of the axis is tilted towards the Sun and we have summer in the Northern Hemisphere and winter in the Southern Hemisphere, and at the other side we have winter in the Northern Hemisphere and summer in the Southern Hemisphere. So for example, while it is cold up here in Canada, Australia is enjoying warm, sunny weather. This would not be the case if the seasons were caused by proximity to the Sun.

Answer 2

Seasons are not caused by closeness to the sun. The earth is closest to the sun around January 1, which of course is the cold season in Europe and and the U.S. (and everywhere else in the northern hemisphere).

The seasons are caused by the tilt of the earth's axis. In June, the north pole is tilted toward the sun, and the north half of the planet gets the most sunlight. In December, the north pole is tilted _away_ from the sun, so the north half of the planet gets relatively little sunlight. So the northern hemisphere experiences summer in June and winter in December. In the southern hemisphere, the seasons are exactly opposite.

Answer 3

The seasons are caused by the 23&1/2 degree tilt of Earth's axis. During northern hemisphere summer, the Northern hemisphere is tilted toward the sun, receiving more direct rays than in winter, thus making it hotter. In winter, the reverse is true.

Answer 4

No actually the Northerm hemisphere winter takes plce during the perigee of the earth's orbit and summer during the apogee.

Seasons are caused by the earth tilting on its axis during rotation which shortens or lengthens the days and makes the sun filter through more atmosphere to strike the surface.

Answer 5

False. Seasons are caused by the tilt of the earth's axis which causes the sun's rays to shine directly on the earth's surface in summer and indirectly in the winter.

Answer 6

No, seasons are caused by the 23 degree tilt of the Earth's axis.

Answer 7

It is obviously untrue if it can be summer in the south and at the same time winter in the northern hemisphere.

The seasons are caused by the tilt of the earth and the orbit of the Earth taking one year.
