Answer :

Final answer:

Altitudes impact oxygen availability by having fewer air molecules and lower air pressure, affecting oxygen density.


Explanation:

Altitude affects the availability of oxygen molecules due to the variation in air pressure. At high elevations, such as mountain peaks, there are fewer molecules of air, resulting in lower air pressure. This leads to oxygen molecules being less densely packed compared to sea level locations.
