float in vs float on The verb "float" can take two different prepositions (i.e. "on" and "in") as in the following sentences: "Why do icebergs float in the sea?" "Why do icebergs float on the sea?" Are there any difference between the two? But then in some cases such as "I couldn't swim so I was just floating in[on] the water/pool," the version with "in" sounds better to my ear, but I don't know why and I'm confused. Can you help me? Thanks.
