Where does the noonsun fall during both equinoxes?

During both equinoxes, the noonsun falls directly on the equator.

Here's why:

* Equinoxes occur when the Sun is directly overhead the equator. This means the Earth's axis is tilted neither towards nor away from the Sun.

* Noonsun refers to the point where the sun reaches its highest point in the sky at midday.

* Therefore, during the equinoxes, the noonsun is directly over the equator, as that's where the Sun is positioned.

This results in equal day and night hours across the globe during the spring and autumn equinoxes.
