Temperature increases with every one degrees of increasing depth.
Explanation:
As one moves from upper layers in the atmosphere downwards into the earth and goes beyond the asthenosphere toward the boundary of the outer core the temperature increases from -600 to 6600 degrees. As the outer and inner core is located at the depth of 5150 kilometers reaching there is itself a difficult task.
The outer core being of liquid matter, the layer is of 2,260 kilometers of thickness and composed of iron and nickel and has an outer boundary of 2,890 km from the earth's surface. The temperature at the outer core register to about 4400 degrees and inner to about 6100 °C.
This liquid in the core is responsible for the existence of magnetic fields on earth which in turn deflects the solar winds which otherwise would have destroyed the plant's atmosphere.
