1. North American cultural pluralism: This is a diversity ranging from ancestral to traditional origins, and these two population groups practice different cultures and live side by side in a separate state.

While the United States has no official language and re-elects many ethnicities, Hispanics, Asians and African Americans. Diversity in Canada and the United States is due to immigration and crossing cultures.2. Physiographic regions: Some of the major regions of North America are the Rocky Mountains, the Great Plains, and the Appalachians. North America is diverse by these physical characteristics. The Pacific Mountains extend from southern California to Canada/Alaska, and the Rocky Mountains from Alaska to New Mexico. The Great Lakes create a plain and the glaciers create a large fertile plain. The Appalachians extend from Georgia to Nova Scotia. From north to south, the terrain changes enormously, changing resources and services.3. Rain shadow effect: This effect begins along the West Coast, in Seattle and Portland, when moisture arrives from the Pacific Ocean, the Pacific Mountains and the Rocky Mountains, which pushes the humidity upward , cools it and makes it rain. As the air mass moves over land, it becomes dry, producing little rain in the Great Plains. North America then only becomes humid the closer we get to the Gulf of Mexico. Many air masses accumulate moisture as they pass through the Great Lakes. Due to the lack of rain in the central United States, the population is high on the west and east coasts.4.
