soil development volcanic eruption plate movement fossil formation
I gave my students this multiple choice question: The principle of uniformitarianism states that most of the landscape of Earth was formed slowly and over a long period of time. Which occurrence of Earth is least supported by this principle?

Only one answer is correct among these 4 choices:
- soil development
- volcanic eruption
- plate movement
- fossil formation

Could you tell me which one is correct?

volcanic eruption
