Answer:
If I were studying this volcano, I would be using the element of geography called “physical systems.” This is because I would be studying the Earth’s natural systems. I would be figuring out how this volcano works and why it erupts. I might also be using the element of geography called “environment and society.” I would be learning about how this volcano affects the societies and people that live nearby. This volcano is part of the environment, and it is going to affect people's lives.
