How does the tilt of Earth's axis affect how the sun's rays strike Earth?
1 Answer
See explanation.
Explanation:
At any instant , the Sun-facing hemisphere of the Earth
has a zenith and a nadir.
The latitude difference for these points is nearly
If there is no tilt, the line of centers of the Earth and the Sun will
pass through the equator of
strike normal to the equator, casting no shadow at all, at every noon.
Elsewhere, the angle of in incidence of these ( parallel ) rays will
be the latitude, for ever.. Noon-shadow length will be
(vertical height) X tan (latitude ). Latitude is
pole, wherein the Sun will be at the horizon, for ever.
The tilt of
the angles of incidence
during the orbital period of one year. This causes local seasons.. .
