Detailed explanation-1: -Oceanic Crust is the thinnest layer of earth.
Detailed explanation-2: -The Crust is the thinnest layer of the earth as it has been mainly generated due to igneous processes, and the operations have not extended much in the other earth-forming layers. This reason also explains why the earth has a host of incompatible elements compared to the Core or Mantle.
Detailed explanation-3: -“Crust” describes the outermost shell of a terrestrial planet. 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. “Crust” describes the outermost shell of a terrestrial planet.
Detailed explanation-4: -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-5: -Troposphere. The lowest and thinnest layer of the atmosphere is called the troposphere. According to NASA, the average thickness is about 7.5 miles.
