Because the air is thinner up there. There is less oxygen in the air, so it is harder to breathe.
Answer: Because the percentage of oxygen in the air is not as much as it is at sea level. When higher altitude is attained, oxygen levels drop. Hope this helps.
There is less air pressure at the top of the mountain which means that all the air molecules you are trying to breathe are farther apart than they are at sea level which makes it seem like it is harder to breathe because you aren't getting quite as much as you're used to. To counter this your body creates a larger number of red blood cells and increases their size so they can transport more oxygen throughout your system.

No, it would be harder to breathe on top of Mount Whitney (or any other mountain) do to the air being thinner. The thin air at higher elevations has less oxygen in it than at sea level (air at 10,000 to 14,000 ft has only 60-70 percent of the amount of oxygen in the air at sea level). Therefore with each breath you don't get much oxygen.

That depends on your definition of "mountain".
The answer is sea level. Because atmospheric pressure decreases when altitude increases
Is the bottom of the mountain at sea level?Is the bottom of the valley 200 feet above sea level?Do you want to know how much higher the mountain is than the top of the valley (which may be the mountain itself) or the bottom of the valley - in which case it would be 800 feet.this is called a mountain
600 feet if the mountain is already below sea level and so is the valley then just subtract the difference
