Detailed explanation-1: -Oceanic Crust is the thinnest layer of earth.

Detailed explanation-2: -Answer and Explanation: 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: -Answer and Explanation: The Earth’s crust is thinnest under the ocean. The crust under the ocean is thinner because the crust under the water that is too old goes deeper into the mantle.

Detailed explanation-4: -Troposphere. The lowest and thinnest layer of the atmosphere is called the troposphere. According to NASA, the average thickness is about 7.5 miles.

Detailed explanation-5: -Summary. Oceanic crust is thinner and denser than continental crust. Oceanic crust is darker in color and denser (more mafic). Continental crust is lighter in color and density (more felsic).
