The layer of the Earth that is mostly solid with some large bodies of water is the crust.

Here's why:

* Crust: This is the outermost layer of the Earth. It's relatively thin and consists of solid rock, but it's also divided into oceanic and continental crust. Oceanic crust is denser and thinner, found beneath the oceans. Continental crust is thicker and less dense, forming the landmasses. The oceans are bodies of water that sit on top of the oceanic crust.
