A region's vegetation is LEAST likely to affect the preservation of folk culture.
That is because the presence of vegetation in a given land, while it is featured in the local people's culture (represented in their pictorial arts or in their cuisine, for example), does not necessarily endanger the <u>preservation</u> of the culture as a whole.
However, if the economy and/or the agriculture are reliant on this type of vegetation, a change in the vegetation can have direct consequences on these activities. Similarly, if a plant is important in the people's diet, they are more likely to gather around the areas where the plant grows (distribution of population). And if the plant is less available, the population may stop thriving, reproduce less, and maybe emigrate (size of population).

Answer: As altitude increases, atmospheric pressure decreases
Explanation:
Atmospheric pressure 
is defined as the force 
per unit area 
the air that forms the atmosphere exerts on the Earth's surface:
It should be noted that as the altitude increases less air is above and, therefore the air weights less. This is because the atmosphere losses density as we ascend, causing less air.
However, it is important to point out this decrease in pressure is not linear, since at the beginning (in the first kilometers above sea level) it reduces more rapidly than in the next kilometers above. That is why this relationship between atmospheric pressure and altitude is exponential.
