Final answer:
The correct answer is option water. Modes of transportation ultimately come in two categories: ground and water.
Step-by-step explanation:
The correct answer is option water. Modes of transportation ultimately come in two categories: ground and water. Ground transportation includes vehicles like cars, buses, and trains, while water transportation includes ships, boats, and submarines. These modes of transportation are critical to our global supply chains for the manufacture of consumer goods.
The correct answer is option "air." Modes of transportation ultimately come in two categories: ground and air. Ground transportation includes vehicles such as cars, trains, and buses that travel on the surface of the Earth. Air transportation, on the other hand, includes various aircraft such as airplanes, helicopters, and hot air balloons that travel in the Earth's atmosphere.
Ground transportation can be electrified, as seen with trains and buses that have the capability to use overhead wires or a third rail for power, therefore reducing the reliance on petroleum-based energy. As the demand in cities for efficient travel grew, transportation methods evolved from horse-drawn carriages to electrified mass transit ways.
Planes, among other modes of transport, predominantly run on petroleum-based energy. However, for intercity travel, options such as personal cars, car rentals, passenger trains, and commuter air flights are considered. Companies, such as Greyhound Lines, Inc. and Trailways Transportation System, are part of the intercity bus service market which is a subset of the broader intercity transportation market.
