23.5 degrees is the angle by which the Earth's axis departs from perpendicularity
referred to the plane of its solar orbit.
If that angle were zero, then there would be no seasons, and the duration of daylight
and darkness would remain constant throughout the year.
If the angle were 90 degrees, a very interesting cycle would follow:
-- With regard to the length of day and night, the equator would be the equivalent
of today's Arctic and Antarctic Circles.
-- Twice a year ... let's say on March 21 and September 21 ... every place on
Earth would have a 12-hour day and a 12-hour night.
-- From then on, over a small band adjacent to the equator that grew continuously,
the days would grow continually longer on one side of the equator and shorter
on the other side.
-- After 3 months, every place on 1/2 of the Earth would have 24 hours of daylight,
and everyplace on the other half would have 24 hours of dark.
-- Then the daylight would get shorter on the lighted half, and the darkness would
get shorter on the dark half, until after another 3 months, every place on Earth
would have 12 and 12 again.
-- The average daily temperature would roughly follow the portion of every
24 hours during which the sun is up, and that duration would vary from zero
to 24 hours and back again to zero, everywhere on Earth, every year.
-- I think I've visualized that correctly. If not, I hope other contributors will
jump in here and straighten me out.
It's doubtful that life on Earth could survive that cycle.
No. Earth's orbital eccentricity (a measurement of the difference between the closest and farthest approach of the Earth to the Sun) has negligible effect on seasonal changes. Rather it's earth's axial tilt that gives rise to seasons.
It would more correct to say that the Earth has seasons because it tilts, rather than saying the Earth tilts to make seasons.
False. The seasons on Earth are primarily caused by the tilt of the Earth's axis rather than its distance from the Sun. While the Earth's orbit is elliptical and does cause slight variations in distance, the axial tilt (approximately 23.5 degrees) leads to the changing seasons as different parts of the Earth receive varying amounts of sunlight throughout the year.
It can be 10 degrees or it could be 70 degrees.
A location at 18 degrees north and 103 degrees east lies in Thailand, specifically in the northeastern region of the country. It is not a specific landmark but rather a point within the country.
The moon does not directly affect Earth's seasons; rather, it is the tilt of Earth's axis that causes the change in seasons. The moon's gravitational pull does play a role in creating tides on Earth, but this does not impact the changing of the seasons.

The two seasons that begin with solstices rather than equinoxes are summer and winter.

You should get Oracles of seasons the minish cap rather the links awakening.

Seasons change because of the Earth's tilt on its axis. The varying degrees that the Earth tilts determines the Earth's seasons. So, the more eccentric the tilts, the more unusual the seasons are also well as the timing of the seasons.
It is not in any city, rather, it is a volcano.
Nothing - The polarity of an electromagnet depends on the direction of current flow and you can effect the same change in orientation to the earth's field by moving the electromagnet rather than the earth's field.
It can be 10 degrees or it could be 70 degrees.
The movement of air and water caused by Earth's rotation is known as the Coriolis effect. This effect is a result of the deflection of moving objects, such as air and water, due to the rotation of the Earth. It causes fluids to curve rather than moving in a straight line in the Northern and Southern Hemispheres.
