At different places one earth, depending on elevation, air pressure varies. What causes air pressure?
sleet_krkn [62]
Weight of air

Depending on elevation, the air pressure varies. This is because of the weight of the air that is exerting pressure on earth. At higher elevation, there is less layer of air that is exerting pressure so the atmospheric pressure is also less. At lower altitudes or at sea level, more layer of air is exerting pressure so the atmospheric pressure is also more. The sun’s energy has nothing to do with air pressure. The energy that the Earth gets from the sun is more or less constant. The same with density of nitrogen, and the earth’s magnetic field, they have nothing to do with air pressure.

Scientists at Russia’s Vostok Station in eastern Antarctica drilled the longest ice core ever recorded. They compiled this graph
Wittaler [7]
The data supports the fourth choice, that increasing air temperature and CO2 levels correlate with a decrease in dust concentration.

The first choice is unlikely to reflect dust concentration, and is more likely to be for air temperature. The second choice is false, because the dust concentration is more of a decreasing trend. The third choice is not true, as the spikes in air temperature and atmospheric CO2 concentrations seem to occur simultaneously, implying a positive correlation.
