Detailed explanation-1: -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. The outer core, about 2, 200 kilometers (1, 367 miles) thick, is mostly composed of liquid iron and nickel.
Detailed explanation-2: -The earth is made up of three different layers: the crust, the mantle and the core.
Detailed explanation-3: -The structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core. Each layer has a unique chemical composition, physical state, and can impact life on Earth’s surface.
Detailed explanation-4: -The Core is made up of two layers, the inner core and outer core. Seismic evidence tells us that the inner core is solid while the outer core is liquid. The inner core has a radius of 1 216 km and the total radius of the core is 3486 km.
Detailed explanation-5: -The solid, outer layer is called the crust. Below the crust lies a layer of very hot, almost solid rock called the mantle. Beneath the mantle lies the core. The outer core is a liquid mix of iron and nickel, but the inner core is solid metal.
