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:

the answer is :

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).   so the answer is a.
