SOLAR SYSTEM

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 liquid part of the Earth’s interior is called the outer core. The outer core surrounds the innermost layer, the solid inner core in the very center of the planet. Surrounding the liquid outer core is the viscous mantle and then the outermost layer, the crust.

Detailed explanation-3: -The outer core of the Earth is a liquid layer about 2, 261 km thick composed of iron and nickel which lies above the Earth’s solid inner core and below its mantle. Its outer boundary lies approximately 2, 890 km (1, 800 mi) beneath the Earth’s surface.

Detailed explanation-4: -The core is separated into two parts: the outer core and the inner core. The Earth is separated into the crust, mantle, outer core, and inner core. The inner core is the innermost layer of the Earth. It is solid and distinct from the outer core, which is a liquid.
