Heat and pressure Soil deposition Rain and wind River formation
I gave my students this multiple choice question: The Davis Mountains in West Texas used to be taller than they are now. Which of the following conditions most likely caused the mountains to become shorter over time?

Only one answer is correct among these 4 choices:
- Heat and pressure
- Soil deposition
- Rain and wind
- River formation

Could you tell me which one is correct?

Rain and wind
