Sunlight, solar radiation that is visible at Earth''s surface. The
By mass, the Sun is about 70.6% hydrogen and 27.4% helium. In much smaller amounts, the Sun also contains oxygen, carbon, nitrogen, magnesium, neon,
On Earth, the solar radiation varies with the angle of the Sun above the horizon, with longer sunlight duration at high latitudes during summer, varying to no
The Sun''s gravity pulls all of its mass (mostly hydrogen and helium) into an almost perfect sphere. Down at the core of the Sun, the temperatures
As a matter of fact, life could not exist on Earth without the Sun. Its many characteristics include its magnificent size and the processes that carry its
Sunlight passing through the earth''s atmosphere is attenuated, or reduced, by about 30% by the time it reaches the earth''s surface due to such effects as (Gast, 1960; Iqbal, 1983):
At its core, sunlight is not merely a source of light; it is a complex mixture of electromagnetic radiation that profoundly influences life on Earth. Exploring this
