Compression at the earth's core
WebThe Earth's core was discovered in 1906, when Oldham (1906) inferred the existence of a low-velocity region inside the Earth from changes in the amplitude of compressional waves traveling through the Earth's interior. Over the last century, a wealth of knowledge on the nature and dynamics of the core has been obtained. WebTopic 3. The Earth as a Heat Engine . The Earth is a body of stored heat, radiating into space. This heat is associated with two things; one is that the very high temperature of the inner parts of the Earth are very high, and the other is the result of heat generated due to radioactive decay of material in the deep Earth.
