Question

1. which of the following diagrams represents midnight at point a?

Explanation:

Midnight occurs when a location on Earth is facing away from the Sun. In diagram C, point A is on the side of the Earth that is opposite to the Sun, which means it is in darkness (midnight). In diagram A, point A is on the side of the Earth that could be in daylight (assuming the Earth is lit by the Sun). In diagram B, point A is too close to the Sun - Earth line and not in the dark side. In diagram D, point A is on the side that is not facing away from the Sun.

Answer:

C.
