Hurricanes form when hot air and cold air start colliding above water and they start to form a tornado but there is water in the tornado. Certain places on earth are more susceptible to hurricanes because they are closer to the coastlines. For example, in Iowa, and Illinois, they have a lower chance of a hurricane, while Florida, and Washington have a higher rate because they are along the ocean. Hope this helps.

-- nuclear fission
-- nuclear fusion
-- radioactive decay.
Any of these makes it a true statement.
The less valence electrons the more reactive the element is.
