GEOLOGY

Detailed explanation-1: -Oceanic crust is thinner and denser than continental crust. Continental crust is much thicker than oceanic crust. It is 35 kilometers (22 miles) thick on average. All three major rock types-igneous, metamorphic, and sedimentary-are found in the crust.

Detailed explanation-2: -The oceanic crust is, on average, much thinner than continental crust and ranges in thickness from 6 to 10 kilometers. This is in part because oceanic crust is recycled through tectonic forces, and continental mostly is not.

Detailed explanation-3: -The Earth is covered by two kinds of crust-continental and oceanic. The thinner oceanic crust is normally a little more than four miles thick, while the thicker continental crust is often as much as 25 miles thick. Continental crust is also much less dense than its oceanic counterpart.

Detailed explanation-4: -Earth’s crust is generally divided into older, thicker continental crust and younger, denser oceanic crust. The dynamic geology of Earth’s crust is informed by plate tectonics.

Detailed explanation-5: -It is thinner than continental crust, or sial, generally less than 10 kilometers thick; however, it is denser, having a mean density of about 3.0 grams per cubic centimeter as opposed to continental crust which has a density of about 2.7 grams per cubic centimeter.
