Is the centre the Earth a ball of Liquid Magma?

By Chris Abraham 8.4

The Core is made up of two distinct layers, a liquid outer core and a solid inner core. The Core is made up of iron - nickel alloy. The core is about 5 times as dense as the rock we walk on at the surface. Seismologists study the seismic waves that are generated by earthquakes. Through this study, seismologists found that the Earth inner core is a solid. The temperature of the inner core is estimated about 5430 degrees Celsius. The range of pressure is about 3, 300, 000 - 3, 600,00 atm (unit). At such a high temperature and pressure no humans can travel to the centre of the earth. No, the inner core of the Earth is not liquid magma.
