3. what is the thickness and volume of the earth's sedimentary rock shell in various tectonic processes?

Earth's sedimentary rock can be explained from the crustal plates on earth.

Explanation:

Earth's most sedimentary rocks are formed in continental or land crust as the oceanic crust is made up of heavier materials such as basalt and has a density of 2.9g/cm cube. The tectonic forces that originate deep within the earth layers and the arrange of rocks found at greater depths which are responsible for the density and thickness of the continental land crust are volcanism and earthquake activity. Igneous and metamorphic rocks that form along with the sedimentary rocks in the earth's crust and areas of shallow beds close to the shores of continental shelves are of less density and less thickness and those submerged beneath this layer are those of higher mass and density. About 40 % of the earth's surface and 70 % of the continental volume is dominated by the earth's crust of terrestrial in origin. In due course of time, the mountain upliftment and isostasy formations have developed the crustal thickness.
