Final answer:
The structure of civilization in North America was influenced by geography and climate, leading to different cultures and societies. Central and South America had advanced agricultural civilizations while North America had more fragmented societies due to challenging climate conditions.
Step-by-step explanation:
The structure of civilization in North America was different from that of Central and South America due to geographic and climate factors. In North America, the geography was characterized by vast plains, mountains, and forests, which influenced the development of different cultures. For example, the Native American tribes in the Great Plains region relied on bison hunting and adopted a nomadic lifestyle. In contrast, Central and South America had diverse geographical features such as rainforests and high mountains, which supported the growth of advanced agricultural civilizations like the Mayans and Incas. These civilizations developed complex political systems, monumental architecture, and sophisticated agricultural techniques.
Furthermore, the climate in North America was often harsh and varied, with extreme temperatures and seasonal changes. This made it challenging for societies to establish permanent settlements and led to more fragmented cultures. On the other hand, the climate in Central and South America was more stable, with fertile lands suitable for agriculture. This allowed for the development of large-scale agricultural societies that could support dense populations.
In summary, the structure of civilization in North America differed from that of Central and South America due to the influence of geography and climate. These factors shaped the cultures, economies, and political systems of the respective regions.
