USA HISTORY

Detailed explanation-1: -Steamboats, which moved across rivers and a network of canals built in the first half of the century, were a cheaper and faster way to transport large amounts of supplies, humans, and animals. Railroads, which developed rapidly after 1830, were also widely used by the Union and the Confederacy military forces.

Detailed explanation-2: -As armies traveled farther from railways, horses and mules also became more and more critical to logistics. Used to haul wagons and cannons, these animals were vital sources of transportation for men, food–both for themselves and the soldiers–and other supplies.

Detailed explanation-3: -Transportation in the United States is facilitated by road, air, rail, and waterways. The vast majority of passenger travel occurs by automobile for shorter distances, and airplane (or railroad, in some regions) for longer distances.

Detailed explanation-4: -Aided by federal land grants, there was a great deal of railroad construction after the Civil War, especially in the West. Trackage increased from 35, 000 miles in 1865 to 254, 000 miles in 1916, the eve of America’s entry into World War I.
