I am OK with most of these, because they reference landforms in one way or the other.
There are two that don't seem to fit because of the origin of the term:
Ocean's 11 refers to someone's last name, not the ocean. But I get why you may think of the Ocean when reading the title.
The one that really grates as different though is Delta Force. It's the Greek letter delta, not a river delta. Seems unrelated to the meaning of the quiz.
One of my favourite ever pub trivia questions was during a round of listening clues for songs referencing countries- eg Born in the USA, Back in the USSR. It included "I Ran" by a Flock of Seagulls. In summary, origin of the term goes out the window and puns are awesome ;)
Just once, I wish people would get into the spirit of the quizzes and stop their bloody nitpicking! (and no, I am not British, but you wouldn't print my first choice))

And I agree with the above....puns are awesome!
