Question
Why do high altitude areas have brighter sunlight and lower temperatures as compared to the plains?
✓

Answer

High altitude areas have brighter sunlight because at high altitude there is a very low concentration of dust particles and atmospheric gases which absorbs the sunlight. There is a low atmospheric pressure at high altitudes. Lower atmospheric pressure results in lower temperatures at high altitudes.
