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.

Which type of energy is in chocolate?
Food energy, which is a type of chemical energy.
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.
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?

What is the radiation called when the suns energy bounces back from the earth?
The radiation that bounces back from the Earth's surface is called infrared radiation. This type of radiation is emitted by the Earth's surface in the form of heat and is partially absorbed by greenhouse gases in the atmosphere, contributing to the Earth's energy balance.
What type of energy does a greenhouse gas transfer to nitrogen and oxygen?
A greenhouse gas primarily transfers infrared energy to nitrogen and oxygen. This energy is absorbed and re-emitted by greenhouse gases in the atmosphere, contributing to the Earth's greenhouse effect and warming the planet.
What type of radiation is trapped on the Earth's surface by the Greenhouse effect?
Infrared radiation is the type of radiation that gets trapped on Earth's surface by the greenhouse effect. This radiation is emitted by the Earth's surface in response to the incoming solar radiation and is absorbed and re-emitted by greenhouse gases in the atmosphere, leading to the warming of the planet.
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.
In what form is radiant energy reflected back into space?
Radiant energy is reflected back into space in the form of infrared radiation, which is a type of electromagnetic radiation. This process helps to maintain Earth's energy balance and regulates the planet's temperature.
Which part does reach earth - longer wavelength infrared or shorter wavelength infrared?
Longer wavelength infrared radiation reaches Earth. This type of infrared radiation is also known as thermal infrared, which is emitted by the Earth's surface and is an important component of the Earth's energy budget. Shorter wavelength infrared, such as near-infrared, is mostly absorbed by the atmosphere and does not reach the surface.
Is NOT a type of high-energy radiation that is reflected or absorbed by Earth's atmosphere?
High-energy radiation such as X-rays, gamma rays, and cosmic rays are not typically reflected or absorbed by Earth's atmosphere. These types of radiation can pass through the atmosphere and reach the Earth's surface, posing a potential hazard to living organisms.
What type of energy is produced when a heated chemical glows?
Photons are emitted (light energy) and infrared energy.
What type of radiation is in the atmosphere due to greenhouse gases?
Infrared radiation is the type of radiation trapped in the atmosphere due to greenhouse gases. This radiation is emitted by the Earth's surface and is absorbed and re-radiated by greenhouse gases, such as carbon dioxide and water vapor, leading to the warming of the Earth's surface.
What type of radiation do greenhouse gases help trap in the atmosphere?
Greenhouse gases help trap infrared radiation in the atmosphere. This type of radiation is emitted by the Earth's surface after it absorbs energy from sunlight. By retaining this heat, greenhouse gases contribute to the greenhouse effect, which warms the planet. This process is crucial for maintaining a stable climate but can lead to global warming when excessive greenhouse gases accumulate.
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.
