-- At any point on earth, the days would be the same length all year around.
-- The noon-time sun would be at the same altitude in the sky all year ... directly
overhead on the equator, lower as you move away from the equator.
-- At the poles, the sun would never rise or set, just scoot all the way around
the horizon once a day.
-- There would be no seasonal variation in local climate ... no cold season and
warm season, just minor day-to-day weather changes all year around.
-- There would be no annual variation in local climate, i.e. no 'seasons'.
-- At each place on Earth, the noon altitude of the sun in the sky would be the
same every day of the year ... overhead on the Equator, lower for places farther
from the Equator.
-- Every place on Earth, except the poles, would have 12-hour days and 12-hour nights,
all year around.
-- At the north and south poles, the sun would be exactly on the horizon, going
around and around every day, never rising or setting.
The south pole would be persistently colder but the extent of the cold area of Antarctica would be smaller.
If the incline was less steep, then the earths seasons would be reduced. Steeper, and the earths seasons would be exageratted.
It would mean there were no more seasons. We would have one season (comparatively to spring or fall) all year round.
Angle of inclination is a fancy term for earths tilt. So the angle of inclination is 23 1/2 %.
Mercury
Approximately 23°. As a matter of interest, the Tropics of Cancer and capricorn are 23° from the Equator, these representing the most northerly/southerly points on the Earth where the Sun can be directly overhead. This is due to that tilt of the earth.
23.45 degrees
Basically no! If you were to take an axis of 0 degrees to be completely vertical (in reference to the Earths orbital plane) then the Earths actual axis is 23.44 degrees (hence we have summer and winter) although this does vary over a 42 thousand year period between 22.1 degrees and 24.5 degrees.
This titled position of the earths axis is known as inclination of the earths axis. The earth's rotation axis makes an angle of about 66.5 degrees with the plane of its orbit around the sun, or about 23.5 degrees from the perpendicular to the ecliptic plane.
The Earth's tilt, or inclination, or obliquity is about 23.44 degrees from the plane of its orbit around the Sun.
Earths orbital inclination is 1.57869°
The Earth's axis is tilted at about 23.5 degrees from the perpendicular to the orbital plane. Or to put it another way, the Earth's equator is tilted at 23.5 degrees to the Earth's orbital plane. The main effect is to cause the seasons. That's because the tilt affects the amount of sunlight a particular place gets as the Earth orbits the Sun.
The Earths Inclination A+
Angle of inclination is a fancy term for earths tilt. So the angle of inclination is 23 1/2 %.
Mercury
the earth spins on an imaginary line called axis.
Approximately 23°. As a matter of interest, the Tropics of Cancer and capricorn are 23° from the Equator, these representing the most northerly/southerly points on the Earth where the Sun can be directly overhead. This is due to that tilt of the earth.
polar satallite
The equatorial plane is the flat surface perpendicular to the axis of the earth through the largest part - i.e. the equator. Since the axis tilts at 23+ degrees, so does the plane.
23.5 degrees
