How is suspense Created in 'What Lies Beneath?'

I pasted a small clip to define how suspense is created because it has short little moments which create huge suspense to the viewer such as when the shoe flies out from the boat so therefore this makes the audience realise that Norman may be in the boat and when she stops the car this makes the audience shout and say 'why are you stopping?' therefore this clip is once again following the Bomb theory. And the last suspense moment is when he crashes into the car and starts grabbing his wife therefore this precise moment grabs the audience attention and creates a huge tension.
