Question

what are the metals are obtained in core layer​

Answer 1

Explanation:

The outer core is about 1,400 miles thick, and it's made mostly of a combination (called an alloy) of iron and nickel, along with small amounts of other dense elements like gold, platinum, and uranium. These metals can, of course, be found on the surface of Earth in solid form. In the outer core, they're in a very hot liquid form. How hot? Try between 7,000-9,000º F!

The inner core, which is about 750 miles thick, is made primarily of iron. Unlike the outer core, the inner core is mostly solid. Although the iron in the inner core is even hotter (10,000º F or more — as hot as the surface of the Sun!) than the outer core, the intense pressure from the rest of the planet is so great that the iron cannot melt.
