      No, it is the water that looks blue because it reflects the blue pigment from the sunlight. The planet would look like the sahara, coz everything would dry up.

      No, water in the oceans is blue because it reflects the blue of the sky. Without water, the planet would all dry up, so the forests would all die, and the planet would like the middle of North America when viewed from space. Something like Mars, or this:

      No, the stuff underneath the oceans is basically the same stuff as the land, so it would look a lot like bare earth/rock. Kind of like desserts and canyons, so maybe a sort of yellowy brown colour.
