Question

During a full moon, the moon appears as a complete circle in the night sky. After the full moon phase, the moon will appear to decrease in size moving through the phases in reverse order.

The moon, like the Earth and the sun (and everything else), has gravity. Its gravity pulls slightly on the Earth. The tides of the ocean happen because of the gravity from the moon (and the sun). The moon's gravity pulls the oceans up a little bit, and that creates high tides. Different phases of the moon create different tides.

Which of the following best describes the effect the moon has on the tides?

A
The gravity of the moon pulls the ocean, which causes the tides.

B
When the moon is invisible in the sky, tides cannot be seen.

C
Tides only happen at night when the moon is visible.

D
The moon produces light, making it possible to see the tides at night.
