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

Detailed explanation-2: -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-3: -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-4: -There are two kinds of crust. 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.

Detailed explanation-5: -Answer and Explanation: The thickest interior layer of the Earth is the mantle, which is about 1800 miles thick. The layer called the outer core is about 1400 miles thick. The thinnest interior layer of the Earth is the inner core, which is just about 800 miles thick.
