mountain ranges to the west high mean elevation frequent earthquakes soil with a high sand content
I gave my students this multiple choice question: Nevada is much drier than regions in California that are at the same latitude. Compared to these regions in California, which feature of Nevada contributes most to this dry climate?

Only one answer is correct among these 4 choices:
- mountain ranges to the west
- high mean elevation
- frequent earthquakes
- soil with a high sand content

Could you tell me which one is correct?
