Leticia is a space scientist who made this diagram of the Moon and Earth as seen from above (top view), with sunlight coming from the left, as shown by the arrows. Why does Leticia’s diagram show that it’s brighter on the left half of the Moon?

• Because Leticia’s diagram is showing that the half of the Moon that is facing the sun is lit by the sun, and the other half is dark.

• Because the Moon has some lighter-colored rock and some darker-colored rock, and Leticia’s diagram is showing that the half of the Moon with the lighter-colored rock has rotated to the left.

• Because as the Moon gets closer to the sun, more of it is lit by the sun, so Leticia’s diagram is showing sunlight on half of the Moon.

• Because there is a shadow from Earth falling on half of the Moon, and Leticia’s diagram is showing that shadow on the right half of the Moon.
