Answer 1

The core of the Earth is a most inaccessible part of the earth.

Explanation:

The core forms the most inaccessible part of the earth as there is no direct and valid information about the core of the earth to Geoscientists.  

The core of the earth has a radius of 3,485 km is hot, very dense, and has heavy elements that were formed 4.5 billion years ago.  

As one goes deeper into the earth's crust the thickness increases and extends down to the mantle for 2,900 km in mantel to 5,080 km in the outer core and 6,371 km in the inner core. Composed of nickel, iron, and hard rocks.

Another core element that makes up the core of the earth is sulfur that creates intense heat and pressure in the core that can even melt the iron. Another factor is a magnetism that is about 50 times stronger than it's on the surface.

Except for that high amount of temperature which goes on the increase for every depth as we travel making it more inaccessible to reach the core. This coming out alive is unimaginable.

Hope it helps you....
