If a modern nuclear weapon were sunk into the ocean would it cause a chain reaction in the water's hydrogen turning the earth into a sun?

no


Which nuclear reaction is used on earth to produce electricity?

Nuclear fission


How many times can a nuclear war destroy earth?

not worth thinking about , a nuclear war would in itself be a chain reaction causing humanitys elimination . the earth cannot be destroyed but we can .


Which type of nuclear reaction is more important for life on earth?

1.The sun is a huge ball of nuclear fusion. 2.We here on earth use nuclear fission to produce electricity. so the answer is 2.


What is a nuclear reaction like on earth?

It is really scary it is like a bom a big boom


Can fission happen on earth?

Yes, all natural radiation (in the rocks) is a result of fission (but this fission is not part of a chain reaction like in a fission bomb). However, it is theoretically possible for natural processes to concentrate radioactive elements (uranium) to the extent where a natural nuclear fission reactor (a chain reaction like in a nuclear power plant) will form. Oklo in in Gabon is the only known location for this to have happened and consists of 16 sites at which self-sustaining nuclear fission reactions took place approximately 1.7 billion years ago.


Does nuclear fusion occur?

Nuclear fusion occurs at the core of the sun (and other stars) providing huge amount of energy to the rest of the solar system. It has also been achieved on Earth, though not in a controlled and sustained manner.


What is the major problem with fusion reactions as an energy source?

Problem on nuclear fusion is upon confinement of reaction in earth atmosphere. Nuclear fusion required very high temperature to initiate the reaction. Sustaining reaction is not easy. It is likely the earliest nuclear fusion will be available commercially by 2050. It is a little far future for the current energy crisis would reach it peak around 2040.


Is there a place other then the Sun that nuclear reaction happens?

Yes - all the millions of other stars in the Universe, where fusion occurs. Also of course fission reactions in all nuclear reactors on earth


Which kind of nuclear reaction is the source of the sun's energy?

The Sun, like other stars similar to it, is sustained by a Nuclear Fusion Reaction at its core. Unlike Nuclear Power here on Earth, which is created by the process of splitting atoms (Nuclear Fission) Fusion creates energy by fusing atoms together. This has proven a difficult objective to achieve here on Earth - though it occurs naturally in stars, on Earth the problem is containment, a problem that has as yet not found a viable solution. Though the extreme gravity of stars is what initiates a fusion reaction in them, it has been theorized recently that a fusion reaction at smaller levels with chemicals is possible. This is commonly referred to as "Cold Fusion" for the relatively low amount of energy it would produce in contrast to nuclear fusion. Though Cold Fusion has largely been discounted, it continues to be researched. Often the biggest scientific breakthroughs are made by those who do not always hold to conventional scientific beliefs. If we did, we would have never done things like go to the Moon, or broken the Sound Barrier. In the time before it happened, both were considered by mainstream science as "impossible" to achieve.


How long was a warp bubble sustained on earth?

.0025 miliseconds


When the sun blows up do the other planets blow up to?

yea they do when one blows up a chain reaction happens earth will go second
