Astronomy - Assignment ExampleThe material time interval of the earth according to their density has played a vital role in this process. It has a truly abstruse metallic core, comparatively less dense rocky mantle and low density crust. It ability have happened two ways the heat raised by radio active combination that caused the privileged melting, and the energy created by its formation process. The answer for how the earths external crust became less dense is clear. It happened as the densest materials submerged in to the melted interior of the planet.As mentioned earlier, the heat created by the radioactive decomposition reaction or the internal melting inwroughtly have the tendency to flow out. Subsequently some other natural phenomena such as convection currents, magnetic field, plate motion, faults, volcanoes, and many more occur. As the outer crusts are comparatively cooler, the outward flow of heat through them makes the earth always geologically active. The moon or other small planets are cool and inactive because they are small in size and have midget heat flow from interior (Seeds, Backman,
