Why seasonal changes occur?

Answer 1

The cause of seasonal variation is the tilt in the Earth's axis. As the earth orbits the sun different parts of the earth become directly aligned with the suns energy heading rfrom north to south and back again over the period of a year or 1 revolution.

Answer 2

The amount of solar radiation absorbed by an object is relative to the angle at which it hits the object, and when the northern hemisphere is tilted toward the sun, the sunlight hitting it is more direct. The 21-degree tilt of the earth's rotational axis with respect to the plane of its solar orbit causes sunlight to hit the northern hemisphere for a longer period of time each day the closer you get to the summer solstice and the closer you get to the north pole. With the summer solstice only a month behind us, that's why it's currently the hottest time of the year in the northern hemisphere and the coldest time of the year in the southern hemisphere. At the time of the summer solstice, the north pole is as close as it ever gets to pointing at the sun; at that moment the sun is directly over the Tropic of Cancer.

Answer 3

We have seaons due to the earths rotation around the sun. The closer we are the hotter it gets which is summer and the farther we get the colder which forms winter and fall and spring are the the middle of the line so to speak.

^ this is wrong. actually it is because of the earths tilt of its axis, which is 23.5 degrees. during the northern hemispheres winter, the axis is like this. (see illistration) actually, the closer we get to the sun, the colder it gets... hmmm...

Answer 4

Seasonal changes occur due to the tilt of the Earth's axis as it orbits the sun. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to the changing seasons. Factors such as distance from the sun and the Earth's elliptical orbit also play a role in seasonal variations.

Answer 5

The Earth's rotation causes seasons.
The earth's revolution around the sun.

Answer 6

because of the earth orbits the sun and its orbital around the sun!

Answer 7

Seasons occur because of :

1) @The tilt of the Earth's axis

1) @The Earth's revolution around the sun
