Question 1605Navigation General

The correct answer is C) between the Earth and the Sun. When the Moon is between the Earth and the Sun, known as a "new moon," the side of the Moon facing the Earth is not illuminated, so the new Moon cannot be seen in the sky. This is because the Sun's light is shining on the side of the Moon facing away from the Earth. The other answer choices are incorrect because: A) At quadrature, the Moon would be visible in the sky, just not fully illuminated. B) If the Moon was below the horizon, it would not be visible for a different reason. D) If the Moon was in the opposite direction of the Sun, it would be a full moon, which is visible.
