In the United States, areas on the west side of a mountain range typically receive more precipitation than similar areas on the east side of the mountain range. Which of these factors is least important in explaining this phenomenon?

i am a little confused myself with what goes with the letters and what goes with the numbers but ill do my best to you

the cordillera states and grand canyon are along the southwest u.s. and northern mexican pacific.

the great plains and southwest desert are also the prairie and home to many earthquakes too .

the coastal plains have poor soil and many factories started in the south.

is this what u needed? if not i can see what i can do
