When air rises, it expands and cools, which causes its density to decrease. Conversely, when air descends, it compresses and warms, which causes its density to increase.
Increase.

An increase in air density will mean a decrease in the absorption and radiation of energy. An increase of air density causes temperature and pressure to rise.
No. Density does not mean there has been a rapid increase in population. It means there are a large number of people living in a small geographic area, as in "New York City has a dense population."
An increase in temperature usually causes an increase in volume. Since the mass doesn't change, density decreases. tt

The population density in LA continues to increase despite the many suburbs. The Asian country with the greatest population density is Bangladesh.
