The reason for this is that the ocean floor is ever changing and is never in the same possition due to current.
earths crust includes ocean floors and
The Earth's crust is the outermost layer of the Earth. It is divided into two types: continental crust, which forms the continents, and oceanic crust, which forms the ocean floors.
Geothermal activity has revealed new characteristics of Earth's crust near Lake Myvatn, Iceland. In places like Iceland, new research has shown volcanoes and hot springs forming as the result of activity between the crust and the mantle.
The Earth's crust includes oceanic and continental categories, the oceanic crust composed of basalt rock and recycled in roughly 150 million year intervals by lithospheric plate movements, and the older less dense continental crust, composed of granitic rock.
mid ocean ridges
The Earth's crust is the outermost layer of the planet, consisting of solid rock that forms the continents and ocean floors.
The thinnest layer of the Earth's crust is typically found beneath the ocean floors in regions known as mid-ocean ridges. Here, tectonic plates are moving apart, creating new crust and allowing magma to rise closer to the surface.
Crust
The Earth's crust is the outermost layer of the Earth and is divided into the continental crust, which makes up the landmasses, and the oceanic crust, which forms the ocean floors. The continental crust is thicker but less dense than the oceanic crust.
The Earth's outer solid layer is called the crust. It is the thinnest layer of the Earth, making up the continents and ocean floors.

falseThe Earth's crust is quite variable in density and thickness. Some places on the ocean floors it is many miles thinner than on land.
