Joe, a hiker, stands at the top of a hill on a trail above the ocean. Joe's friend Dave is just starting out at the trailhead, which is at the beach. Which statements about Joe and Dave are accurate? Select three options. Joe is at a higher altitude than if he was at the beach. The air Joe is breathing is less dense than the air at sea level. The air pressure is higher where Joe is than where Dave is. If Joe keeps going up, air pressure will continue to decrease. The air Joe is breathing is denser than the air Dave is breathing.

The correct answer is b) The air Joe is breathing is less dense than the air at sea level.

a) Joe is at a higher altitude than if he was at the beach.

d) If Joe keeps going up, air pressure will continue to decrease.

Explanation:

The altitude is the distances considering the sea level to the different points of the earth, in the mountains the altitude increases and at that height the atmospheric pressure decreases, causing a decrease in the pressure of oxygen, and as the pressure of oxygen decreases the people can suffer accidents like losing consciousness.

For example, in the case of Joe, he has a higher height than David that is on the beach, this makes the air have less pressure since the pressure of the atmosphere has decreased. If Joe continues going up, the pressure of the air he breathes will continue to decrease and Joe may have an accident because it is difficult for the body to adapt to the change in altitude.

I hope this information can help you.
