What percentage of light hits earth’s surface directly? 3 percent 5 percent 31 percent 47 percent

Option (4)

Explanation:

The earth receives heat from the two main sources, namely from the core of the earth and from the sun. These two sources togetherly form the earth's heat engine. This heat engine allows the earth to transfer heat from one surface to another.

The earth receives strong incoming solar radiations, of which about 71% is absorbed by the earth's heat system and the remaining 29% is reflected back into space.

From this 71% of total heat (light) energy, about 23% of incoming solar energy is absorbed in the upper part of the atmosphere by the water vapour, ozone layer and other dust particles.

The remaining 48% is directly incident on the earth's surface and are eventually absorbed.

Thus, according to the given question, nearly 47% of light (incoming solar radiation) hits the earth's surface directly.

Hence, the correct answer is option (4).

c.31 percent on edge:)

Explanation:

c.more precipitation,but only when emission levels.

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
