Question

Which term best describes a nuclear chain reaction?. A)self-sustaining. B)weak. C)non-explosive

Answer 1

I took the Earth Science Nuclear Energy Quiz and the correct answer is self-sustaining.

I hope this helps you!

Answer 2

Since we're talking about a chain reaction, I think this would be a) self-sustaining. Chain reactions are not usually described as "weak" and can be highly explosive depending upon the compounds (think Uranium!). The first (artificial) self-sustaining nuclear reaction is attributed to Enrico Fermi in 1942. Here's a bit of history: http://www.atomicarchive.com/History/firstpile/firstpile_01.shtml
