Answer:

Atmospheric pressure always decreases with increasing height.

Step-by-step explanation:

A drinking straw is used by creating a suction with your mouth. Actually this causes a decrease in air pressure on the inside of the straw. Since the atmospheric pressure is greater on the outside of the straw, liquid is forced into and up the straw.
