Question

air becomes _dense when we go to higher altitudes.​

Answer 1

The density increases as pressure increases. Altitude and weather systems can change the air's pressure. As you go higher, the air's pressure decreases from around 1,000 millibars at sea level to 500 millibars at around 18,000 feet. At 100,000 feet above sea level the air's pressure is only about 10 millibars.
