Homework Help: chemistry

I did a lab on pressure and depth today. This lab was to simply submerge a plastic tube into a large graduated cynlinder to find the relationship between the two. I found that as the depth increases, so does the pressure. One of the questions I'm stuck on for part of my lab report is this one:
On a molecular level, describe why you think this is happening.

As the depth increases, there are more molecules on top pressing down.

Thank you!
What would be the difference if a small graduated cylinder was used instead of a large one? The pressure would still increase as the depth increases? What about the molecules?
