The primary geographic feature of the Great Plains region is its vast expanses of flat or gently rolling terrain, characterized by grasslands. Extending from Canada to Texas in the United States, the Great Plains are essential for agriculture, particularly for growing wheat and raising cattle. The region's fertile soil and favorable climate support farming activities, which have shaped the economy and lifestyle of the inhabitants. The Great Plains also host a variety of wildlife and are vital for migratory bird populations, contributing to the area's biodiversity.
