USA HISTORY

Detailed explanation-1: -Industrial expansion and population growth radically changed the face of the nation’s cities. Noise, traffic jams, slums, air pollution, and sanitation and health problems became commonplace. Mass transit, in the form of trolleys, cable cars, and subways, was built, and skyscrapers began to dominate city skylines.

Detailed explanation-2: -One important result of industrialization and immigration was the growth of cities, a process known as urbanization. Commonly, factories were located near urban areas. These businesses attracted immigrants and people moving from rural areas who were looking for employment. Cities grew at a rapid rate as a result.

Detailed explanation-3: -Urbanization Begins in the United States “Cities grew because industrial factories required large workforces and workers and their families needed places to live near their jobs. Factories and cities attracted millions of immigrants looking for work and a better life in the United States.”

Detailed explanation-4: -Having people concentrated into small areas accelerated economic activity, thereby producing more industrial growth. Industrialization and urbanization thus reinforced one another, augmenting the speed with which such growth would have otherwise occurred.
