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.

The Inner Structure of the Earth refers to the different layers that compose the planet: inner core, outer core, matnle and crust.
1. Crust. Earth’s crust is what we walk on every day. It is the thin (relatively) outermost layer that wraps around the Earth and ranges in temperature from 500 to 1,000°C.
We rely on Earth for valuable resources such as soil, water, metals, industrial minerals, and energy, and we need to know how to find these resources and exploit them sustainably.
Earth’s Layers (The internal structure of the Earth) The crust is a silicate solid, the mantle is a viscous molten rock, the outer core is a viscous liquid, and the inner core is a dense solid.
