The layer that is thinnest under the oceans is the crust. While it  is thinnest in those underwater regions, it is the thickest in the  regions where mountains are.
Some of the crust is mostly terrestrial (forming the continents), but much of it is marine (underlying the bottoms of the oceans). The rigid material that floats on Earth's surface is termed the lithosphere. The low velocity plastic layer (molten magma) under the lithosphere is called the asthenosphere.
