Question
What is insolation ? Explain the factors that influence it.
Solution
Insolation : The energy received by the earth in the form of waves of short wave-lengths is known as incoming radiation or in short insolation.
Factors that influence isolation :
1. The amount and the intensity of insolation vary during in a day, in a season and in a year. The major factors that cause these variations in insolation are rotation of the earth on its axis, the angle of inclination of sun's rays and the length of the day.
2. Other modifying factors are transparency of the atmosphere and the configuration of landmass in terms of its aspects.
