Because it gives them the opportunity to have a gratuitous beauty shot. Someone says "I want this shot!" and then they make it fit into the story (badly)
The shot of the Enterprise rising from the ocean was for posters really, that and the shot in the trailers of a starship crashing was to lead the audience to believe the ship would be destroyed in a crash landing.
Not unlike the rumours of Spocks death in STII being put out and then he "dies" in the first few minutes on the simulator. So the filmmaker are carrying on Trek tradition of misleading the audience.
