Looking inside our planet
You may have learned from your textbook that Earth is made up of four layers: the crust, the mantle, the outer core, and the inner core. But according to a new study, there may be a fifth layer inside Earth.
Scientists at the Australian National University(ANU) found this new layer within Earth's inner core. They call it the "inner-inner core".
The inner core, more than 5, 000 kilometers below Earth's surface, is hard. It's made of iron alloy. But starting from 5, 800 km below Earth's surface, scientists have found some changes. f They found there are iron crystals pointing in an east - west direction. But other iron crystals in the inner core point in a south - north direction. This difference makes the inner - inner core a new layer.
Earth used to be very hot before it cooled down. According to Joanne Stephenson, one of the researchers, this new finding suggests another cooling event in Earth's history.It can help us understand more about how Earth formed.
