Why do mountain climbers wear oxygen masks to minimize the chance of health hazards or even death?
The air at high altitudes is denser, so it is harder to breathe in enough oxygen.
The air at high altitudes is less dense, so it is harder to breathe in enough oxygen.
The air at high altitudes sinks, so it is harder to breathe in enough oxygen.
The air at high altitudes rises, so it is harder to breathe in enough oxygen.
