Technically no, but valid guess. At night, the sun's rays reflect off the moon and back on to Earth. The reason the light is so much dimmer is because a lot of light energy is lost in the process.
The Earth does not emit light, it like the moon reflects light
Different chemicals emit and absorb light at various wavelengths. Astronomers can look at the wavelength of light coming from stars and determine which chemicals must be present.
planets, moon,etc do not emit light on their own.
because it can absorb and re-emit the suns energy
No. Stars emit light.
The core would emit light because it is hot. The outer atmosphere would absorb light because it is not completely transparent. It would also re-emit radiation itself, because of its heat.
Spectroscopy is the scientific tool that is based on how atoms absorb and emit electromagnetic radiation. Spectroscopy deals with how an object's light is dispersed into its component colors or energies.
no
fingerprints are made of organic compounds that absorb UV light and then emit visible light.
Black is the color of objects that do not emit or reflect light in any part of the visible spectrum; they absorb all such frequencies of light.

phosphorescent materials do this
Lights are coloured by the light they emit and are additive, while pigments are coloured by the light they absorb/reflect and are subtractive.
The electrons in the electron sea absorb and re-emit the light.
When they exit their exited state. When an atom is bombarded by photons, it will often times absorb the photon. A photon is a unit of energy, so this energy is added to the atom, "extiting" it. However, atoms may only remain in ths excited state for a short period of time, and will eventually release the photon, reemiting it as light, and then the atom will return to its normal state.
It seems readily apparent that trees reflect light, since you don't see them glowing at night.
Fluorescence. It happens when atoms' electrons absorb light at one frequency and emit at other (usually lower) frequencies. Sometimes two photons are absorbed by the same electron, and emitted as a single higher frequency, but this is not common.
