Hi, I'm Marshall Brain with today's question. When I stand at the water's edge and look out over
the ocean, how far away is the horizon. One of the funniest things about the ocean is the fact that its surface is curved. We tend to think about water forming large flat sheets, but the surface of a body of water is not actually flat at all. It follows the curvature of the Earth because of the curvature of the planet. The distance between you and the horizon when you look out over the ocean depends on your height
above the surface of the water. If your eyes are eight inches above the water, the distance to the horizon is about a mile. If you're six ft tall and standing right at the water's edge, then your eyes are about five and a half feet above the surface. The distance to the horizon is about three miles in that case.
