GENERAL GEOLOGY

Detailed explanation-1: -Earth’s core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly solid mantle. The core is found about 2, 900 kilometers (1, 802 miles) below Earth’s surface, and has a radius of about 3, 485 kilometers (2, 165 miles).

Detailed explanation-2: -Inner core. The central part of the earth which is in solid state is inner core. The Earth has an outer solid layer called the crust, a highly viscous layer called the mantle, a liquid layer that is the outer part of the core, called the outer core, and a solid centre called the inner core.

Detailed explanation-3: -Answer: The other term for the word core is Centre.

Detailed explanation-4: -Core: It the innermost layer of the earth. It has the heaviest minerals of highest density, Nickel and Iron i.e Nife. The outer core is liquid while the inner core is solid.

Detailed explanation-5: -Earth’s core consists of a solid iron-nickel ball rotating within a layer of liquid metal. But that ball may not be as simple as it seems: new research suggests the inner core contains its own inner core. If so, this so-called innermost inner core may record an early phase in Earth’s evolution.
