Question

why can we see the moon at night? light from the sun is reflected back to us off the moon. light from the sun is absorbed by the moon. light from the earth is reflected back to us off of the moon. the moon is luminous and produces its own light.

Explanation:

The moon is not a luminous body (it does not produce its own light). The light we see from the moon is sunlight that is reflected off the moon's surface. If the light was absorbed by the moon (as in the second option), we would not see it. The light is not from the earth (third option). And the moon is not luminous (fourth option).

Answer:

Light from the sun is reflected back to us off the moon.
