| Effect of Altitude on climate and seasons: |
|
Definition
1. At low angles, the sun's rays pass through more of the atmosphere. Radiation is weaker and modification of the visible spectrum is greater.
2. As a given sun-beam is spread over a greater surface area, the sunlight energy on each square unit of land is weaker (also called cosine law). |
