Question

which area of west virginia tends to have the most rainfall?
the eastern panhandle because precipitation increases on the east side of the mountains.
the ohio river valley because of river water evaporation.
the allegheny highlands because this is where clouds collide with the west side of the mountains.

Explanation:

The Allegheny Highlands receive more rainfall because when clouds collide with the west side of the mountains, it causes precipitation. The Ohio River Valley has less rainfall due to river water evaporation not directly leading to high - rainfall in the same area. The Eastern Panhandle having precipitation on the east side of mountains is not as significant for overall high rainfall as the cloud - mountain interaction in the Allegheny Highlands.

Answer:

The Allegheny Highlands because this is where clouds collide with the west side of the mountains.
