Which of the following correctly explains how air exerts pressure on us? the molecules in the air located above us are pulled down towards the earth by gravity, causing a downward pressure on objects below. the normal force produced by the earth against our bodies causes the air to be pressurized. the difference in the amount of air outside and the amount inside of our bodies creates air pressure. the strength of molecular bonds between air molecules is greater than the strength of bonds between molecules in our bodies, creating pressure.
