A male child standing on top of a rock that extends over a body of water.
A child is looking down into the ocean from behind the safety rail at a lookout point.
Not every body of water is an ocean, and just because a child is on top of a rock that is over a body of water does not mean they are looking down, behind a safety rail, or at a lookout point.
