erosion of surrounding continental materials eruptions of continental shield volcanoes convergence of continental plates subsidence of continental landmass
I gave my students this multiple choice question: The Himalayan Mountain chain is the youngest and tallest mountain chain on Earth. Which phenomenon contributed most to this area of continental buildup?

Only one answer is correct among these 4 choices:
- erosion of surrounding continental materials
- eruptions of continental shield volcanoes
- convergence of continental plates
- subsidence of continental landmass

Could you tell me which one is correct?

convergence of continental plates
