Question
The solar radiation coming to Earth is called
Answer: Option A
Answer: (a)
Insolation is the solar radiation that reaches the earth’s surface. It is measured by the amount of solar energy received per square centimetre per minute.
Insolation affects temperature. The more the insolation, the higher the temperature. On any given day, the strongest insolation is received at noon.
The insolation into a surface is largest when the surface directly faces the Sun. As the angle increases between the direction at a right angle to the surface and the direction of the rays of sunlight, the insolation is reduced in proportion to the cosine of the angle.
