Simple Answer:
Most of the energy emitted from the Earth is infrared energy, just below the visible spectrum we can see. A portion of this energy is absorbed by the atmosphere, particularly by water vapor and carbon dioxide in the Earth's atmosphere.
Planets have some heat.
The Earth and other planets retain some residual heat left form the time planets and the Sun were formed four or five billion years ago. In addition, there are some internal sources of heat such as radioactive decay. Earth and other planets also gain heat from the Sun.
Planets lose heat.
Overwhelmingly, the mechanism for heat loss is through radiation of heat. All objects radiate heat in the form of electromagnetic radiation. (One can look up "black body radiation" which is an interesting topic in its own.) For Earth, this is typically characterized as infra-red radiation. The radiation is emitted from the Earth, through the atmosphere and heads out into cold space.
(Space, all the apparent emptiness we see in the night sky, is at a temperature of about 4 degrees Celsius above absolute zero, compared to our temperature of almost 300 degrees above absolute zero. The cooling through radiation of the hot Earth is evident in our daily lives because the cooling we experience at night can be so dramatic. In particular, clouds prevent much infrared radiation from directly escaping. A cloudy night cools several degrees less than a clear night.)
There are complications.
Though there is no question that the Earth loses heat by radiating it into space, the details get complex. There are a lot of complications about how much energy of this sort is absorbed by the atmosphere and that leads to discussions of the Greenhouse Effect, but that can be left to another question. There is a complex balance of energy incoming and energy radiated that can occupy a long discussion.

What type of cycling involves movement of chemical elements through through the earth living things and the atmosphere?
biogeochemical
Are specific colors of light emitted by an atom in a hot thin gas caused by electrons jumping to lower energy levels?
Not sure what you mean by "specific," but some light being emitted from a hot thin gas is, indeed, caused in that way. Other light is simply black body radiation, which does not depend on the type of atoms in the gas, but only upon the temperature of that gas.
Which type of energy is in chocolate?
Food energy, which is a type of chemical energy.
What is vibrations that travel through earth carrying the energy released during and earthquake?
A specific type of mechanical wave known as a seismic wave.
What kind of energy is in a food web?
Food energy, which is a type of chemical energy.
What type of energy is collected from the sun?
The energy collected from the sun is called solar energy. The energy gets to the earth from the sun by radiation that has been affected by the earth's atmosphere.
What type of energy is produced when a heated chemical glows?
Photons are emitted (light energy) and infrared energy.
What type of energy is emitted by greenhouse?
water vapor and carbon dioxide
What type of energy enters the Earth's atmosphere from the sun?
The energy Earth receives from the Sun is often called solar energy. The rate at which this energy arrives at Earth is about 174 petawatts ( 1 petawatt = 1,000 trillion watts) at the upper atmosphere. About 30% is reflected back to space. The sun energy at the Earth's surface is mostly in the visible and near-infrared ranges with a small amount in the near-ultraviolet.
What type of energy is transmitted through the atmosphere?
Through the atmosphere rather than by the atmosphere, then that would be electromagnetic energy.
What is meant by type atmosphere?
the atmosphere is the blanket of gases that surrounds earth
Earth's surface radiates heat as what type of radiation?
If we consider sun as planet, I would say that the solar flames covering the sun acts like a shield [similar to the atmosphere acting as a shield for the earth].In that case there might even be life existence in the sun. If this assumption comes true then i would say that the earth gives out wind energy, because we consider the sun's shield the solar flames to give out heat energy, similarly we can just say that the earth's shield the atmosphere gives out wind energy. this is just my assumption!
What type of energy is received on earth from the sun and other stars?
Heat, visible light, and infrared light (UV Rays) are the three main types of energy emitted from the sun and stars. Although, around 30% of it does get forced back into space.
