Answer:
Explanation:
Mankind seems to learn very little from anything -- good or bad. There are many things you could say about Natural Gas or Oil, but one thing that neither one could do is create another Chernobyl.
People are saying that the cleanest and most efficient way to go would be to use Nuclear Power Plants. I admit that Gas and oil create their own set of environmental problems, but nothing as far reaching as something lasting 35 years as Chernobyl has done
Scientists are bewildered by Chernobyl heating up again. They cannot explain why let alone what can be done. Each of the alternate energy choices have their problems and have their ill effects on the environment.
The heaviest elements settled in the Earth's center during the formation of Earth's lithosphere
<u>Explanation:</u>
Earth's lithosphere comprises the crust and the uppermost mantle, which form the strong and rigid external layer of the Earth.
The Earth, on the other hand, begins with a core of iron and radioactive materials such as uranium and plutonium, which deliver energy in the form of heat, within a process known as nuclear fission. It passed by a fusion stage - a "liquid-pasty" state - which provided that, due to gravity, the more solid materials dropped towards the center, while the smaller ones floated towards the crust, a process called planetary differentiation.
