Hemp seeds, or hemp hearts, have a high nutrition profile and are a healthy addition to most diets. Hemp seeds are the seeds of the same plant as marijuana, the cannabis plant, but they do not contain high levels of THC and will not get you high.
Nuclear explosion. Atomic bomb explosion. A nuclear explosion is energy being released from a very fast nuclear reaction. It can be caused by nuclear fission, nuclear fusion, or both. Atmospheric nuclear explosions are associated with mushroom clouds, although mushroom clouds can occur as a result of large chemical explosions.
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion. Both reactions release vast quantities of energy from relatively small amounts of matter. Even small nuclear devices can devastate a city by blast, fire and radiation.
