Input: Answer this question:
Why do mountain climbers at high elevations use oxygen tanks to help them breathe?
OPTIONS:
- At high elevations the ozone layer draws oxygen out of the atmosphere.
- The atmosphere is less dense at higher elevations so there is less oxygen available.
- Oxygen is heavier than the other gases in the atmosphere and sinks to lower elevations.
- Radiation from the Sun splits oxygen molecules into atoms making the oxygen unbreathable.
