Why are there seasons on earth?

Question

Why are there seasons on earth?

Answer 1

Cuz God wants it that way.

Answer 2

At various time in its 365 day journey around the sun, eithr the northern hemisphere is tilted towards the sun or then southern hemisphere is. Tilling towards the sun, is summer, and away from the sun is winter. In between it is spring and fall.

Answer 3

The earth wobbles on it's axis and tilts the poles one way or the other during the year and that results in the seasons... and is also why the seasons are opposite each other on each side of the Equator

Answer 4

IT'S BCOZ OUR earth is tilted an angle of 23.5 degrees to the vertical axis and this causes the climatic change.

Answer 5

Seasons are not caused by the earth tilting.

There is a tiny wobble in the earth's rotation but it does not affect the seasons. What does cause them is the fact that the axis is permanently tilted.

This affects the nearness to the sun, as well as the wind and ocean current patterns that contribute to the warmth of summer and cold of winter.

Look at

/o  and o/

the o is the sun, the / is the earth's axis, you can see how on different sides of the sun, different ends of the axis are closer (north or south).

The actual distance is quite small, compared with the distance we are altogether, so it is not a direct heating effect, but caused by the angle of the sun being different from the various positions, affecting how the heat is refracted or absorbed by the atmosphere and the earth itself.

It is highly likely that the development of seasons contributed greatly to the formation of continents, as having seasons changed the distribution of temperatures over the surface, allowing some to cool and harden sooner than others. With an upright axis, the equator was always hotter, the poles always cooler, but never by enough to "dry out" into continents. The first continent then got lifted and broken up by the pressures of the imbalance caused by its existence, with earthquake and volcanic activity that remains with us to this day, 100s of billions of years later.
