Earths magnetic field is crucial to life on our planet. The crust varies from around 5km thick (in the ocean floor) to around 70km thick (on land where we live called the continental crust). What is unique about the photoperiod at the two equinoxes? The levels of heat, pressure and radioactivity (one of the main sources of internal heating) are so high that even if we could bore through over 6,000km of rock and metal, a probe would be unable to survive. By the early 20th Century, the increasing temperatures as we dug deeper into the Earth, combined with seismologists analysis of earthly waves, suggested that the inner parts of our planet were at least partly molten hot enough to turn rock and metal into liquid. In general, temperatures range from about 4,400 Celsius (7,952 Fahrenheit) to about 6,000 Celsius (10,800 Fahrenheit).

What is the center of the Earth called? - YouTube Though the seismic waves that cause damage in an earthquake are those that travel on the surface, there are also two types of body wave that move through the Earth. The earth's core is divided into two separate regions: the liquid outer core and the solid inner core, with the transition between the two lying at a depth of 5,156 kilometers (3,204 miles). Geometrically defined it is the centroid of all land surfaces within the two dimensions of the Geoid surface which approximates the Earth's outer shape. The liquid metal of the outer core has very low viscosity, meaning it is easily deformed and malleable. Planets and stars actually orbit around their common center of mass.
