USA HISTORY

Detailed explanation-1: -Waterways and a growing network of railroads linked the frontier with the eastern cities. Produce moved on small boats along canals and rivers from the farms to the ports. Large steamships carried goods and people from port to port. Railroads expanded to connect towns, providing faster transport for everyone.

Detailed explanation-2: -Railroads became a major industry, stimulating other heavy industries such as iron and steel production. These advances in travel and transport helped drive settlement in the western regions of North America and were integral to the nation’s industrialization.

Detailed explanation-3: -Anaconda plan, military strategy proposed by Union General Winfield Scott early in the American Civil War. The plan called for a naval blockade of the Confederate littoral, a thrust down the Mississippi, and the strangulation of the South by Union land and naval forces.

Detailed explanation-4: -The North had geographic advantages, too. It had more farms than the South to provide food for troops. Its land contained most of the country’s iron, coal, copper, and gold. The North controlled the seas, and its 21, 000 miles of railroad track allowed troops and supplies to be transported wherever they were needed.
