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.
In nuclear fission, atoms are split apart, which releases energy. All nuclear power plants use nuclear fission, and most nuclear power plants use uranium atoms. During nuclear fission, a neutron hits a uranium atom and splits it, releasing a large amount of energy in the form of heat and radiation. More neutrons are also released when a uranium atom splits.
