the relative sizes of each state the types of industry found in each state the location of each state on the continent the relative frequency of volcanic activity in each state
I gave my students this multiple choice question: Nevada's annual precipitation averages between 21 and 24 cm. In comparison, Washington state averages between 96 and 97 cm of precipitation per year. Which of these factors has the greatest impact on the difference in precipitation between these two states?

Only one answer is correct among these 4 choices:
- the relative sizes of each state
- the types of industry found in each state
- the location of each state on the continent
- the relative frequency of volcanic activity in each state

Could you tell me which one is correct?

the location of each state on the continent
