volcanic eruptions and global warming earthquakes and tidal activity collision of crustal plates and erosion production of greenhouse gases and weathering
I gave my students this multiple choice question: Which two processes could result in the formation of high mountains with well-rounded peaks?

Only one answer is correct among these 4 choices:
- volcanic eruptions and global warming
- earthquakes and tidal activity
- collision of crustal plates and erosion
- production of greenhouse gases and weathering

Could you tell me which one is correct?

collision of crustal plates and erosion
