Final answer:
Because rivers and canals were an easy method of transportation, many Northern European towns grew up along them.
Step-by-step explanation:
Rivers and canals were vital for transport and trade in Northern Europe, leading to the growth of towns along them. They enabled economic growth and were complemented by advancements like the steam engine and paved roads, which further influenced urbanization. Rivers like the Rhine and the Danube were crucial in defining European geography and facilitating trade and logistics. Canals, such as the Erie Canal, played a significant role in connecting regions and enabling economic prosperity. During the industrial revolution, access to waterways was pivotal due to the dependency on water power and the need for efficient transportation of goods. The development of the steam engine by Robert Fulton in 1807 further enhanced the utility of these waterways, allowing boats to travel both up and down rivers. This technological advancement, in conjunction with other transportation developments, such as paved roads and electric streetcars, significantly shaped urbanization and industrial growth.
