Question

The rain shadow effect would be most evident in which direction relative to the rocky mountains?

Answer 1

The rain shadow effect would be most evident in the “Eastern” direction in relative to the Rocky Mountains.

A “Rain-Shadow” is a dry area that is formed on the side of the mountains which are away from the wind. The rain-producing weather systems are blocked by the mountains and a shadow of dryness is cast on that area, without much moisture left in the air.

The Continental Divide in America acts as a great barrier for precipitation.

The Rocky Mountains are a major mountain range that is present in the western North America and stretch for more than 3,000 miles across the northern part of British Columbia, western side of Canada, till New Mexico, in the South-Western part of the US.

The low pressure systems are known to approach from the south to skirt the Rocky Mountains. They generate high precipitation on the eastern side. However, there is little or no precipitation on the western slope.
