Explanation:

The lithosphere is a rigid and outer most shell of rock that is found on all terrestrial types of plants and is made up of silicon, aluminum, and magnesium and is flexible and behaves elastically on the time scale of the planet for a thousand or millions of years. From time to time the crustal rocks have transpired in shape and save as compared to the oceanic plates that are much larger and are heavier as compared to these continental plates.
