What direction does the earth rotate on a vernal equinox?

Answer 1

Any time and at any latitude, all points on the Earth rotate in the anticlockwise sense about polar axis, in a plane that is inclined to the orbital plane ecliptic, at #23.4^o#.

About the times and locations of the vernal and autumnal equinoxes, which fall on March 21 and September 23, respectively, right-over-head noon-Sun:

Equinoxes are the locations where the ecliptic and equator intersect each year at precisely noon, when the Sun is directly overhead.

After the extremely quick daily rotation, these equinoxes (very slowly) move along the equator for one full extra rotation over a period of roughly 258 centuries.

The tilt axis precessed during this enormous period known as the Great Year, which is the cause of the relative motion of the equinoxes.

Like equinoxes going around the equator in a Great Year, the poles move around small circles of angular spacing #46.8^o# up on the Earth, relative to the center of the Earth.

During a vernal equinox, the Earth rotates on its axis from west to east.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
