About how much of the sun's radiation would strike the earth if the earth did not have its atmosphere?

Had to look for the options and here is my answer.

I can say that it would be ten times as much of the Sun's radiation would strike if the Earth did not have its atmosphere. The Earth's atmosphere consists of different layers which are composed of different gases. Each of these play an important role in enveloping and regulating the Earth's internal temperature. Hope this helps.

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
