|
|
lower temperatures and less oxygen at higher altitudes.
|
|
|
higher temperatures and more sunlight at higher altitudes.
|
|
|
the gravitational pull and flatter terrain at higher altitudes.
|
|
|
better quality soil and more rain at higher altitudes.

Explanation:
Detailed explanation-1: -To effectively acclimatize to higher altitude, you can follow an altitude acclimatization 3-step process: preparation, ascent, and descent.
Detailed explanation-2: -At higher altitudes, the partial pressure of oxygen is less than that at ground level, so that oxygen concentration becomes less in blood or tissues. Hence, people suffer from anoxia.
