What is The Earths Core?

The Earths core

The earth’s core is a molten mass of boiling rock trying to erupt through volcanoes, or is it?

Scientific research has shown that the earth’s core actually consists of a collection of minerals and elements presented as a solid ball made of mostly nickel and iron alloy.

The actual core diameter is roughly 70% of our moons radius, so around 1,211 kilometres. The surface of the earth’s core has a temperature close to that of our sun, around 5,700 K, or 5,430 °C.

This was the discovery of a Danish seismologist by the name of Inge Lehmann in 1936. This inner core is thought to be slowly increasing in size as its surrounding mass cools and solidifies. This central part of our planet rotates inside the solid surface we walk upon at a slightly faster rate than the earth’s known rotation. Only around 1degree each year of extra rotation
