Final answer:
The Wellington-McPherson Lowlands do not cover the Southwest portion of Kansas.
Step-by-step explanation:
The Wellington-McPherson Lowlands do not cover the Southwest portion of Kansas. The Wellington-McPherson Lowlands refer to a physical region in Kansas that is located in the center of the state, east of the High Plains region.
The Southwest portion of Kansas, on the other hand, is part of the High Plains region. So, the statement is false.
