The Inner Core
-The inner core is the second biggest layer of the Earth.
-The inner core is 2,220 km thick.
-The inner core is almost the same size as the moon.
-The solid part of the Earth is known as the inner core and the liquid part is known as the outer core.
-During the creation of the Earth, 4.6 billion years ago, the planet was a molten ball of rock and metal. The inner core is liquid so all the heavier elements like iron and nickel sank to the center of the earth. In fact the center of the Earth probably has huge amounts of gold, platinum and uranium.
