The Geographical History of America

The geographical history of America involves the movement of land masses over millions of years, shaping its diverse landscapes. North and South America originated as part of the ancient supercontinent Pangaea, which broke apart about 200 million years ago. Over time, tectonic plate shifts created mountain ranges like the Rockies and Andes, and landforms such as the Amazon rainforest and Great Plains. The continent’s geography influenced climate, ecosystems, and human settlement. Indigenous peoples adapted to varied environments long before Europeans arrived in the 15th century. Subsequent natural processes and human activity have continued to modify America’s landscape.
