List the five modes of transportation. For each mode provide a brief description (or examples) of the type of cargo that typically travels via that mode of transport

a . MOTOR: Motor carriers are actually quite versatile, so nearly anything from packaged household goods to building materials to liquid petroleum are all candidates to be moved via motor carrier.

b. RAIL: Rail carriers typically carry very heavy shipments. This might include heavy building materials, construction equipment, or coal.

c. AIR: Air carriers typically carry items with a high cost to weight ratio. In other words, air carriers carry very light, high-value goods that need to travel long distances quickly. This might include items like jewelry, fine wines, or even racehorses. On occasion items are also shipped by air because of an emergency, for convenience, or perhaps to offset high packaging and/or insurance costs.

d. WATER: Water carriers typically haul heavy, bulky, low value materials like cold, grain, and sand. Nonetheless, because transport by water is so cheap almost any item may be shipped by water. Some items that typically travel via water carrier include: automobiles, petroleum, liquefied natural gas, containerized cargo, frozen fish, and produce.
e. PIPELINE: Pipelines move materials only when they are in a liquid or gaseous state. Items that would typically move via pipeline include: petroleum, coal in a slurry form, natural gas, drinking water, or gasoline.
