(will give brainliest and ) as an airplane rises through the atmosphere, machines cause the pressure inside the cabin to decrease. as the airplane descends toward earth, machines cause the pressure inside the cabin to increase. explain why these changes in pressure are necessary

These changes are necessary because of gravity 

The answer to this question is:

As an airplane rises through the atmosphere, machines cause the pressure inside the cabin to decrease. As the airplane descends toward Earth, machines cause the pressure inside the cabin to increase. Explain why these changes in pressure are necessary


"These are necessary because the "Atmospheric-Pressure" is on knowledgeable on the land is simulated So that the people can breathe properly without having their heads explode/faint."
