Answer 2

Earth was divided into four parts.They are :-

1) Crust

2) Mantle

3) Inner core

4) Outer core

Explanation:

Crust:- The crust is a thin but important zone where dry, hot rock from the deep Earth reacts with the water and oxygen of the surface, making new kinds of minerals and rocks. It's also where plate-tectonic activity mixes and scrambles these new rocks and injects them with chemically active fluids.

Mantle:- The Earth's mantle plays an important role in the evolution of the crust and provides the thermal and mechanical driving forces for plate tectonics. The mantle is also the graveyard for descending lithospheric slabs, and the fate of these slabs in the mantle is a subject of ongoing discussion and controversy.

Inner core:- Earth's inner core is the innermost geologic layer of the planet Earth. ... Information about Earth's core mostly comes from analysis of seismic waves and Earth's magnetic field. The inner core is believed to be composed of an iron–nickel alloy with some other elements.

Outer core:- Earth's outer core is a fluid layer about 2,400 km (1,500 mi) thick and composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. Its outer boundary lies 2,890 km (1,800 mi) beneath Earth's surface. ... Unlike the inner (or solid) core, the outer core is liquid.
