  • 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.
