The recent frequent earthquakes have helped scientists discover a new core.
This fifth inner core is a solid ball of nickel and iron and is the innermost layer.
It has a different crystal structure that causes shock waves from earthquakes to reverberate through the layer at different speeds than the surrounding core
Earlier there were only four layers of Earth: the crust, mantle, liquid outer core and solid inner core.
Scientists believed that it may be 650 km in diameter and the inner core of the earth is 2,440 km in diameter. It is about 70% of the moon’s size.
Also, it is believed that it is the hottest and densest of all layers. However, this new layer is denser than the other two cores.
