Did you read my post? PF rules state that students must show their attempts at a question before homework helpers can give advice. Have you got any thoughts about the question?

Can you think of anything that would be different if, say, there was no atmospheric pressure?

Where do you think they help in real life?

Name a few things and give an explanation as to why you think buoyant forces or atmospheric pressure relates with this.

We'll tell you if you're right or wrong.

I'll give you a hint; there's quite a bit dealing with oceanic stuff =). Not only there, but even in your home =p.
