Which region of the Earth have almost equal days and nights throughout the year?

equator

Why does the equator always have 12 hours of daylight?

The reason for this is because Earth is tilted 23.5 degrees away from its axis of rotation. If there were no tilt, everywhere on Earth would receive 12 hours of daylight and 12 hours of night every day, regardless of how close or far to the Equator.

This results in an almost uniform balance of day and night throughout the year for locations closest to the equator. Since the equator stays in the same place relative to the sun, the level of sunlight received throughout the year is nearly constant.

Why does the equator appear to be tilted every day?

Because the “circle of illumination” that separates day from night bisects the equator every day of the year. The EARTH is tilted at an angle of 23 and 1/2 degree from its perpendicular. It is a result of this tilt – we have the varying seasons, difference in temperatures, the deserts and the forests etc.

What direction does the sun face at the equator?

Always equal day and night at the equator. Also, the sun faces the whole Earth, technically (okay, or half of the Earth if you must pick that nit). If you mean facing directly, well, that depends on the season. At the June solstice, the sun is most direct at the Tropic of Cancer.
