There would be no seasons. No Winter, No Summer. The days/nights would be of the same length.
The axial tilt that gives us seasons varies between 28 degrees and 21 degrees. Currently, it is 23.5 degrees and reducing towards 21 degrees. This is called precssion, and takes thousands of years to complete one precessive cycle.
So the seasons and daylight hours will vary according to the angle of precession.
NB Note it is PRECESSION , not 'procession.
NNB Any spinning object undergoes precssion. Check a child's spinning top of a spinning gyro. Notice how they 'wobble' when spinning; the Earth does exactly the same.
The Earth is tilted on its axis at approximately 23.5 degrees. This tilt is what causes the change in seasons as different parts of the Earth receive varying amounts of sunlight throughout the year.
Definition of solstice: two days of the year on which the noon sun is directly overhead at either 23.5 south or 23.5 north. I dont know about equinox but i know how solstice is related..So my answer is.... It's related to the earths axis because when the earth is rotating the sun hits north and south but not really at the same time. So that's why north or south would be 23.5 degrees .
The earth's axis is tilted to 23.48 degrees to the ecliptic plane
There would be many changes. First there would be only one season all the time with minor differences when Earth is at perihelion and aphelion. The time of sunrise and sunset would not change and at the equator there would be 12h or night and day.
The tilt of Earth's axis causes the seasons by affecting the angle at which sunlight hits the Earth's surface. When one hemisphere is tilted towards the sun, it receives more direct sunlight and experiences summer, while the opposite hemisphere is tilted away and experiences winter. As Earth orbits the sun, the tilt causes the seasons to change.
There would be no four seasons if the earths axis was not tilted.
Earth is tilted from it axis
Seasons And Climate
The axis of the Earth is tilted 23.5 degress from the plane of the orbit round the sun.
Yes it is tilted at about 23.5 degrees
The Earth's axis of rotation is tilted 23.44 degrees from the plane of the ecliptic.
south
The season
Because Earths axis is tilted.
without the tilted axis the whole planet would be impossible to live on since this angle is a state of equilibrium
Mainly, there would be no seasons.
very very cold
