Detailed explanation-1: -Crust-5 to 70 km thick. Mantle-2, 900 km thick. Outer Core-2, 200 km thick. Inner Core-1, 230 to 1, 530 km thick.
Detailed explanation-2: -Earth’s interior is generally divided into three major layers: the crust, the mantle, and the core.
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 core is made of two layers: the outer core, which borders the mantle, and the inner core. The boundary separating these regions is called the Bullen discontinuity. Outer Core The outer core, about 2, 200 kilometers (1, 367 miles) thick, is mostly composed of liquid iron and nickel.
