Why is it harder to breathe when climbing up a high mountain?(1 point)
The air compresses the lungs.
The air pressure increases.
The air is thinner.
The air has more moisture.
The air is thinner

The correct answer is: the air is thinner.
When climbing up a high mountain, the altitude increases, and as a result, the air becomes thinner. At higher altitudes, the pressure exerted by the air decreases, which means there are fewer air molecules in a given volume of space.
This decrease in air pressure means that there is less oxygen available in each breath you take. Since oxygen is crucial for the body to function properly, the reduced oxygen levels at higher altitudes make it harder for your body to get the oxygen it needs. As a result, you may experience shortness of breath and find it harder to breathe.
To get this answer, you would need to understand the concept of altitude and its impact on air pressure and oxygen levels. Additionally, knowledge of the effects of reduced oxygen levels on the body's ability to breathe is necessary.
The correct answer is: The air is thinner.
When climbing up a high mountain, the air becomes thinner due to lower atmospheric pressure at higher altitudes. This means that there is less oxygen available for the body to take in with each breath. As a result, breathing becomes harder because the body has to work harder to get enough oxygen to meet its needs.
