Questions: Currently, in the United States the greatest volume of goods and services is shipped by water. rail. pipelines. trucks and vans.

The answer is trucks and vans.

Shipping goods by water is significant for international trade and bulk commodities, especially for items like oil, coal, and grain. However, it is not the primary mode for domestic shipping in terms of volume.

Rail transport is crucial for moving large quantities of goods over long distances, particularly bulk commodities like coal, chemicals, and agricultural products. While important, it does not surpass trucks in terms of volume for domestic shipments.

Pipelines are primarily used for transporting liquids and gases, such as oil and natural gas. While they handle a large volume of these specific goods, they do not account for the greatest volume of overall goods and services.

Trucks and vans are the most versatile and widely used mode of transportation for goods and services in the United States. They provide door-to-door service and are essential for the distribution of goods from warehouses to retail locations and consumers. This flexibility and reach make them the dominant mode in terms of volume.
