Rock A mass of mineral matter that makes up the crust of the earth is called rock.Or Aggregates of minerals are termed as rocks. Examples: See part

Three Layers of the Earth Crust Mantle Core.

In 2003, a refined result was yielded by Holger Isenberg: 40°52′N 34°34′E, also in Turkey, near the district of İskilip, Çorum Province, approx.200 km northeast of Ankara. In 2016, Google Maps marked Isenberg’s result of 40°52′N 34°34′ECoordinates: 40°52′N 34°34′E as the geographical center of Earth.

the central, innermost, or most essential part of anything. Also called magnetic core . Electricity. the piece of iron, bundle of iron wires, or other ferrous material forming the central or inner portion in an electromagnet, induction coil, transformer, or the like. (in mining, geology, etc.)

Both the inner and outer cores consist primarily of iron and nickel. They’re extremely hot, with temperatures ranging from 7200–9000℉ (4000–5000℃). The inner core is under intense pressure, which keeps it solid despite high temperatures. Outer Core: The outer core, which is liquid, is about 1300 miles (2092 km) thick.

The structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core.

In terms of its constituent elements, the mantle is made up of 44.8% oxygen, 21.5% silicon, and 22.8% magnesium.There’s also iron, aluminum, calcium, sodium, and potassium. These elements are all bound together in the form of silicate rocks, all of which take the form of oxides.

Internal structures are the inner pieces and parts that keep organisms alive, help them grow, and help them reproduce.
