Which continent has the largest expanse of plains in the world?

The continent with the largest expanse of plains in the world is North America. Stretching across the central United States and Canada, the Great Plains cover a vast area of flat, grassy terrain. This region extends from the Gulf of Mexico to the Arctic Ocean, encompassing states such as Texas, Kansas, Nebraska, and the Canadian provinces of Alberta, Saskatchewan, and Manitoba. The Great Plains are characterized by their fertile soils, which support extensive agriculture and ranching activities. Additionally, they are home to diverse wildlife, including bison, pronghorn antelope, and various bird species. The vastness of the Great Plains has played a significant role in shaping the history, culture, and economy of North America, serving as a vital resource for indigenous peoples, settlers, and modern-day inhabitants alike.
