It might be more correct to say that the earth re-radiates energy. Let's look at what's happening and break it down a bit.
The sun supplies (radiates) energy, and the earth is in the path of some of it. The earth absorbs some of this energy, and it reflects some of it as well. This occurs on the sun-facing side. Of the energy that it absorbs, it will re-radiate some of that energy out into space when that side of the earth turns away from the sun to make it night.
Of course not. Energy is radiated out all the time. The hotter an object, the more energy will radiate away.
All objects radiate energy at a rate depending on their temperature.
the greenhouse effect
Yes, a drum set can radiate sound energy when the surface of the drum vibrates on striking it to set particle molecules in air to transfer energy in a wave form and radiate out.
The Earth radiates energy similarly to the sun. Some of the Earth's material breaks down constantly, which causes heat. This is the source of Earth's internal heat, and what drives plate tectonics.
radiate energy
yes.
The earth does reflect light, but does not produce light.
It cannot radiate because it cannot remain single but joins with a positive ion or proton.
Yes.
thermal energy will always radiate to lower energy matter.
The definition of 'radiate' is to emit energy in the form of waves or rays. More specifically, 'radiate' also refers to energy being released in heat, gas or light form. Synonyms of the word include 'beam' and 'emit'.
