Question

What is the rainfall in the western part of the central plains of North America?
a: low
b:high
c: moderant

Answer 1

Answer:

The major source of moisture is the Gulf of Mexico, and the amount falls off both to the north and west. Thus, the southern plains have 15 to 25 inches (380 to 640 mm) of rain annually, the northern plains 12 to 15 inches, the eastern margin in Nebraska 25 inches, and the western margin in Montana less than 15 inches.
