diastrophism

noun    (Concise Encyclopedia)

Large-scale deformation of the Earth's crust by natural processes, which leads to the formation of continents and ocean basins, mountain systems and rift valleys, and other features by mechanisms such as lithospheric plate movement (see plate tectonics), volcanic loading, or folding.
