The earth is composed of several layers choose the correct option staring from the innermost part earth consists of three main section

Answer 1

The Earth is composed of three main layers, starting from the innermost part:

1. Inner Core - This is the innermost layer, composed mainly of iron and nickel, and is solid due to the immense pressure.
2. Outer Core - This layer surrounds the inner core and is semi-liquid, also made mostly of iron and nickel, and is responsible for Earth's magnetic field.
3. Mantle - Above the outer core, the mantle is semi-solid and makes up the majority of Earth's volume. It behaves like a viscous fluid over long periods and is where convection currents occur, driving plate tectonics.

Finally, above the mantle, we have the Crust, which is the outermost layer where we live, consisting of solid rock.

So the three main sections starting from the innermost part are: Inner Core, Outer Core, Mantle.
