Question

the density and pressure of air .......... with altitude.(fill in the blanks)​

Answer 1

Explanation:

Altitude is height above sea level. The density of air decreases with height. There are two reasons: at higher altitudes, there is less air pushing down from above, and gravity is weaker farther from Earth's center. So at higher altitudes, air molecules can spread out more, and air density decreases (Figure below).
