Final answer:
The primary mode of transportation for petroleum and natural gas is pipelines, which efficiently transport these materials in large quantities. Virtually all forms of transportation currently rely on petroleum-based energy, and LNG is used to store and transport natural gas efficiently.
Step-by-step explanation:
The mode of transportation used primarily for petroleum and natural gas is D) Pipeline. This method is especially efficient for these materials due to their physical states and the large quantities they are usually transported. Pipelines provide a continuous flow and are most practical for these substances over long distances.
Concerning other parts of your question, a large percentage of transportation is powered by petroleum products. Virtually all forms of transportation such as planes, trains, automobiles, and ships run on petroleum-based energy. Petroleum is essential for movement and the manufacture of various consumer goods and materials such as plastics.
For clarity, gasoline is a product derived from petroleum, and natural gas, which is mainly methane, is entirely different and exists in a gaseous state at room temperature. To facilitate its storage and transport, it can be cooled to form Liquefied Natural Gas (LNG), which takes up much less space.
