Get a glass of water and put ice in it what happens, the water rises right. Science says the Earth is 3/4 water, but if you took every living thing and ever rock out of the oceans and lakes and just left water and the ground under, wouldn't the water sink drastically?

What you are referring to is buoyancy, which we have a better understanding, thanks to Archimedes running through the street naked shouting "Eureka." (True story according to history.) Archimedes found that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid. If you remove all the life in the oceans, then you are removing density from it, and the sea levels certainly would drop somewhat. Exactly how much, I couldn't tell you, because I haven't calculated the density of all the life in the ocean on my days off. However, you should also keep in mind that most life is also made up of mostly water. (90%) Also, it is the SURFACE area that is made up of 2/3 (or 3/4 in this version) water, and not that the planet is actually made of 3/4's water.

This same priciple of buoyancy is called isostacy when it comes to land masses. Continents are less dense rocks "floating" on more dense basaltic oceans. As the shape of our continents and oceans change, so will sea level.

Hi. For each cubic mile of submerged material you removed the water would replace a volume of one cubic mile. So, yes. Drastically? No, but equally, yes.

Let's do it and find out. It reminds me of Patton wanting to use his tanks to wipe out all the German U-boats during WW II.
