the greenhouse effect
This process is known as the greenhouse effect, where certain gases in the atmosphere trap heat from the sun and radiate it back to Earth, warming the planet. Water vapor, carbon dioxide, methane, and other greenhouse gases play a role in regulating Earth's temperature by absorbing and re-emitting infrared radiation.
Greenhouse gases.
Atmospheric gases, such as watervapor and carbon dioxide, absorb thermal energy and radiate it back toearth. The gases function like the glasswalls and roof of a greenhouse, allowing solar energy to enter and preventing thermal energy from escaping.
Objects that absorb and radiate heat well are usually made of materials with high thermal conductivity, such as metals like aluminum and copper. These materials can quickly absorb heat from their surroundings and also release it efficiently through radiation. Dark, matte surfaces also tend to absorb and radiate heat better than shiny or light-colored surfaces.
Fire radiates heat through the process of thermal radiation, where electromagnetic waves are emitted from the heated fire source. These waves transfer heat energy to surrounding objects or surfaces that absorb them, causing an increase in temperature.

Because they absorb them better. If a surface were to absorb a certain radiation very well and not radiate it well, an apparatus could be made that violates the Second Law of Thermodynamics (creating a temperature difference where none existed previously). Therefore, it is not possible. You might also say that the dark surface is "transparent in both directions" (in and out). This is for a specific radiation; on the other hand, it is possible to have surfaces that radiate and absorb electromagnetic waves of one frequency well, and not so well at other frequencies.
This would be called the greenhouse effect
Black body emissivity is a measure of how efficiently an object emits thermal radiation. In the context of thermal radiation, black body emissivity is significant because it determines how much heat an object can radiate and absorb. Objects with high emissivity can efficiently emit and absorb thermal radiation, while objects with low emissivity are less effective at exchanging heat with their surroundings. This property is important in various applications, such as in designing thermal systems and understanding the behavior of materials at different temperatures.
Radiation balance refers to the equilibrium between incoming solar radiation absorbed by the Earth and outgoing thermal radiation emitted back into space. The Earth's surface and atmosphere absorb sunlight, which warms the planet, and re-radiate heat energy back into space. This balance is crucial for maintaining Earth's temperature and climate.
