True or False: Days and nights are equal in length everywhere during an equinox.

During an equinox, the lengths of day and night are nearly equal across the globe. This phenomenon occurs because the sun is positioned directly above the equator, which results in sunlight being distributed evenly between the Northern and Southern Hemispheres. As the Earth rotates on its axis, all locations experience approximately 12 hours of daylight and 12 hours of darkness.

It's important to note that while the lengths are very close to equal, there may be slight variations due to atmospheric refraction and the shape of the Earth’s surface. However, the general principle holds true: on both the spring and autumn equinoxes, day and night are nearly of the same length everywhere, making the statement true.
