The kansas/colorado border roughly approximates a north-south line of longitude. the terminator line you drew is almost to this north-south border. this line of longitude is also roughly approximate to el paso sunrise time for this day, since el paso is along the terminator. the terminator orientation relative to north-south longitude lines does, however, change throughout the year. a. parallel b. perpendicular

Parallel

Explanation:

Much of the the borders in between these regions are in along the North-South longitudinal lines.

The terminator lines are in between these regions are almost parallel to the Longitudinal lines along the North-South borders.

The orientation of the terminator of these cities are approximately same while the orientation of the terminator along these North-South lines keeps on changing the entire year.
