Your "which" question isn't really answerable, because you offered no options. However, much of the infrared spectrum of light is strongly absorbed by the atmosphere, and therefore unsuitable for ground-based astronomy.
Radio waves reach the ground which means that they can be viewed from the ground and you don't have to travel up into space to view them. They also can observe phenomena's that other wavelength ranges cannot view.
Astronomy. Until it hits the ground and thereafter belongs to the geologists.
Any kind except X-ray observations.
Because the ground dosen't conduct electricity.

Solar radiation mostly passes through the atmosphere without heating it, due to its wavelength. It does not pass through the ground, however, and it heats the ground. The ground emits radiation at a wavelength dependent on its temperature. This radiation happens to be in the thermal infrared part of the spectrum, or in other words, sensible heat. Therefore, the atmosphere is heated by the surface, whereupon the heat tends to rise and heat the lower atmosphere.
A transformer doesn't 'conduct current through the ground'. However, in the event of a ground fault in the circuit supplied by a grounded transformer, the resulting fault current will flow through the earth back to the grounded terminal of that transformer's secondary winding.

Radio wavelengths below 10 meters cannot be effectively studied with telescopes on the ground due to interference from Earth's atmosphere. UV, X-ray, and gamma-ray wavelengths are also difficult to study from the ground due to absorption and scattering by the atmosphere.
All the current uses. * local news and music * ground penetrating radar * radio astronomy (especially imporatn for exploring the early Universe) * walkie talkies * global communications when the satellites cannot be reached due to ionization of the atmosphere.
Surface runoff that cannot penetrate the ground forms streams, rivers, or lakes.
