1. Susan 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 Susan’s diagram show that it’s bright on the left half of the Moon?
a
Because as the Moon gets closer to the sun more of it is lit by the sun, so Susan’s diagram is showing sunlight on half of the Moon.
b
Because the Moon has some lighter-colored rock and some darker-colored rock, and Susan’s diagram is showing that the half of the Moon with the lighter-colored rock has rotated to the left.
c
Because there is a shadow from Earth falling on half of the Moon, and Susan’s diagram is showing that shadow on the right half of the Moon.
d
Because Susan’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.

We can see on the diagram on the left side arrows that show the way from which sunlight appears. It only lights up the left side of the sun, while the right one stays dark.

The moon does not produce any light or energy on its own, so only the side that is facing the Sun at the moment is lit up. That is also the only side we can see from the Earth.

Because of the way and pace Earth and moon move through space and around their own axis, we can only constantly see only one side of the moon. The other side always stays dark, and it is often called the “far side of the moon”.

The position of the sun and moon also determine the phases of the moon we see from the Earth. If more of the moon is visible, that means the moon is positioned to directly face the sun and be lit up. If we don’t see much, the sun lights up only that portion of the moon.

The correct statement is that half of the Moon that is facing the Sun is lit by the Sun and the other half is dark. So, the correct option that matches the Susan's diagram is D.

The diagram made by Susan is a representation of how the Moon is visible from Earth when one of its side faces the sun as it rotates around the Earth and the position of the Moon.

Rotation of the Moon

The Moon rotates around the Earth. It takes 15 days for one complete rotation around the Earth.

While the Moon rotates, its position that is faced by the Sun is lit as the sunlight provides brightness to the Moon and this bright portion is visible as on Earth.

When the Moon is not getting faced by the Sun due to its rotation, the Moon is not visible on Earth and is known as a No Moon Day.

Hence, the correct option is D that the Susan's diagram shows that half of the Moon that is facing the Sun is lit by the sun and the other half is dark.
