3. Why do ears pop at higher altitudes?
Because the atmospheric pressure is
a lower and the air is less dense at higher
altitudes.
Because the atmospheric pressure is
b higher and the air is more dense at higher
altitudes.
Because the atmospheric pressure and
c density remain same but altitude
changes.
d None of the above.



Answer :

Final answer:

Ears pop at high altitudes due to lower atmospheric pressure and decreased air density.


Explanation:

Ears pop at higher altitudes because the atmospheric pressure is lower and the air is less dense at higher altitudes. As altitude increases, there is less air pressing down from above, causing a decrease in air pressure and air density.
