All nuclear reactions generate radioactive waste. which answer correctly lists nuclear reactions beginning with the cleanest reaction?

D

Explanation:

Radioactive decay is the cleanest because it is natural and stochastic. Therefore, because these radioactive elements will not occur in pure forms, the rate at which it produces radioactive particles is less compared to fusion and fission. Fusion and fission have to be manmade here on earth. Fusion, which combines lighter atoms into heavier atoms releases much energy but fewer radioactive particles compared to fission. Nuclear fission, the splitting of heavier elements to lighter elements, produces the most radioactive waste.

dang that balls went far

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
