Answer:
The Great Plains are the flat landscape east of the Rocky Mountains.
Step-by-step explanation:
The Great Plains are one of the major physical features of the United States, but also of all of North America. They lie east of the Rocky Mountains and west of the Appalachian Mountains. As the name suggests, it is an area dominated by plains, occupying enormous territory.
The Great Plains are relatively flat, having a roughly north-south direction. While they are mostly flat, there are differences in elevation, with the southern part being lower than the northern part. Naturally, the Great Plains were covered by grasses, varying from short to mixed and high grasses, depending on the amount of rainfall. Nowadays, little is left of the natural biomes, and the Great Plains are one of the largest agricultural landscapes in the world, and it is one of the most productive agricultural areas in the world.
