Core:
The core is the innermost layer of the Earth, located beneath the mantle. It is divided into two parts: the outer core and the inner core.

Outer Core:
- The outer core is a layer of molten metal, primarily made up of iron and nickel.
- It is responsible for generating the Earth's magnetic field through the movement of molten metal.
- The outer core is about 2,300 kilometers thick and is in a liquid state due to high temperatures and pressure.

Inner Core:
- The inner core is a solid sphere composed mainly of iron and nickel.
- It has a radius of about 1,220 kilometers and is extremely hot, reaching temperatures up to 5,700 degrees Celsius.
- The immense pressure in the inner core keeps the iron and nickel in a solid state despite the high temperatures.

Short and Long Question Answers - Inside Our Earth:
- The Earth is composed of several layers, including the crust, mantle, outer core, and inner core.
- The core plays a crucial role in the Earth's structure and dynamics, influencing geological processes such as plate tectonics and the generation of the magnetic field.
- Understanding the composition and behavior of the core is essential for gaining insights into the Earth's formation and evolution.
