On the earth surface
Explanation:
The long-wavelength radiation is created on the earth surface when electromagnetic radiation is re-emitted.
- The sun releases radiation in form of short-wave.
- They are usually more energetic and with short wavelength and a high frequency.
- When they interact with materials on the earth, they are radiated back as long-wavelength radiation that usually causes heat.
- Ultraviolet rays and other high energy waves are emitted from the sun because it is a very hot body.
- When these radiations enters the earth, they are re-radiated back as long waves with lower energy.
- Earth is cooler than the sun
- When some of the short waves for example, the ultraviolet rays gets to the surface, it is absorbed and re-radiated back.
- When the short waves are absorbed, they lose some of their their energy to the earth surface.
- The remainder is radiated back as less energetic long waves.
- The hotter a body is, the more energetic the radiation it releases.

Answer:
francium
Explanation:
The most expensive natural element is francium, but it decays so quickly it can't be collected to be sold.
the argument that the researcher supports in this statement is that the Viruses are nonliving
Answer : Option C
<u>Explanation:</u>
Viruses are organic structures and they are often termed as "organisms at the end of life". Virus is not considered a living as it does not have a biological machinery to replicate.It is a parasite and it needs a host to replicate.
The virus tries its entry through the wounds, respiratory tracts and by passing through insects.
The complete virus particle is known as virion which consists of a nucleic acid surrounded by a capsid, Virus first attach themselves to a host through their surface.
That is called desalination
