Which type of transportation is NOT a mode included under Surface Transportation?

Surface transportation encompasses the various means of moving goods and people over land and water, which includes motor vehicles, rail systems, and waterways for vessels. Air transportation, however, operates above the surface and is categorized distinctly because it involves aircraft operating in the atmosphere rather than on the ground or on waterways.

Motor transport refers to the use of vehicles like trucks and cars to convey cargo and personnel across roads. Rail transport involves trains moving along tracks, while water transport includes ships and boats navigating through rivers, lakes, and oceans. Since air transportation involves flying rather than ground-level movement, it does not fall under the definition of surface transportation.
