Synergism.
Synergism happens when two or more chemicals enter the body and create adverse side effects/health concerns because of their use together. The effects of the two chemicals together is greater than the sum of the effects of the two individual chemicals.
The answer is catastrophism.
Catastrophism is a theory explaining that the Earth has been affected by sudden catastrophes which created its geological features. Some of the proposed catastrophes is a global flood followed by an uplifting of some rock which happened sudden, in a short period of time. It is opposite theory to uniformitarianism which explains that the Earth was formed in slow changes.
