Question

complete the paragraph. the base of a mountain has a altitude and air pressure than the top of the mountain. air at the base of the mountain has particles in a given amount of space, so the air is dense.

Explanation:

• Altitude is the height above sea level. The base of a mountain is lower (has a lower altitude) compared to the top.
• Air pressure is related to the weight of the air above. At lower altitudes (base of the mountain), there is more air above, so higher air pressure.
• Looking at the diagram, there are more air particles at the base (in a given space) compared to the top.
• Density is mass per unit volume. More particles in a given space means higher density.

Answer:

The base of a mountain has a lower altitude and higher air pressure than the top of the mountain. Air at the base of the mountain has more particles in a given amount of space, so the air is more dense.
