What effect is seen in mountainous regions due to reduced oxygen availability with altitude?
Answer and explanation
Correct answer: Breathing may become difficult and physiological adaptation is needed
The governing concept is the decrease in atmospheric pressure with altitude. Although oxygen remains about the same fraction of air, the total pressure and therefore oxygen partial pressure decline as air becomes thinner. The body may consequently experience breathlessness and need acclimatisation, including physiological adjustments. Option B is correct; altitude does not instantly raise sea level, stop all rainfall or liquefy every gas.
