Located around 1800 miles below the surface of the earth, the core is a dense collection of iron and nickel. It is divided into two layers. The inner core is solid, and around 780 miles thick. The outer core is so hot that it is always molten, but the pressure found inside the inner core is so great that it cannot melt (despite the fact that temperatures can reach 6700 degrees Fahrenheit). The outer core is 1370 miles thick. The earth’s rotation causes the outer core to spin around the inner core, giving rise to earth’s magnetism.
Who is doing the making? And does making mean manufacturing? Or creation? Or resulting force of various geological processes?
