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.

What is the theory that earths crust is in a slow motion?
Plate Tectonics. The crust is in large, irregular plates shuffling around by new rock extruded from the upper Mantle in ocean plate boundaries, balanced by the loss of the fringes of the ocean-floor plates to subduction.
Why the crust is thinner than the ocean floor?
The crust is the Ocean floor. There is Oceanic Crust, And then There is Continental Crust.

How and why does the earths crust vary from place to place?
The earths crust its 5-70km deep in the ocean and upto 100km deep at mountain ranges. At certain areas, the crust is unstable due to moving plate tectonics.

Why are ocean floors the newest crust on the earth?
