Web2 dagen geleden · Inner Core: The innermost part of Earth is the core and is about 1500 miles (2414 km) thick. Both the inner and outer cores consist primarily of iron and nickel. They're extremely hot, with temperatures ranging from 7200–9000℉ (4000–5000℃). The inner core is under intense pressure, which keeps it solid despite high temperatures. The core of the Sun is considered to extend from the center to about 0.2 to 0.25 of solar radius (140,000–170,000 kilometres (87,000–106,000 mi)).
