WebOuter Core: The outer core, which is liquid, is about 1300 miles (2092 km) thick. Both the inner and outer cores consist primarily of iron and nickel and are extremely hot with temperatures ranging from 7200–9000℉ (4000–5000℃). Mantle: Most of Earth's volume is in the mantle. This layer is about 1800 miles (2880 km) thick. WebThe composition of the earth's core consists of an inner core and an outer core which is dominated by metal elements with different temperatures, shapes, and conductivity. Differences in temperature, pressure, and composition of the outer core cause convection currents in the molten metal to cool, causing denser matter to sink and less dense ...
