I was talking about the entropy in waters of the ocean, not surface crust. Most of the planet is covered by water and it is mostly very warm, if I compare the entropy trapped in the waters of the ocean and the atmosphere, I SUSPECT that there is more entropy in the water and lesser in the atmosphere due to density (perhaps).
Let's say I am correct, most entropy is in the water, then where is its source, sun or volcanic activities on sea floor.
If you look at Moon and Mars, which has more entropy in comparison to earth? I would say earth has more entropy because of its vast waters.
I could be entirely incorrect or dead right, but I need to do some calculations and verify.
