d. Rocky Mountains; western; Atlantic Ocean

Answer 1

The Great Plains region extends westward to the Rocky Mountains from around the eastern 100th meridian, starting from the Mississippi River.

Step-by-step explanation:

The Great Plains region extends westward to the Rocky Mountains from around the eastern 100th meridian - an imaginary line running north and south from the Mississippi River. This area is known for its vast and level agricultural land, which changes from fertile soil suitable for corn and soybeans in the east to drier conditions that favor wheat production as you move west towards the Rocky Mountains. The transition at the 100th meridian reflects a shift in precipitation patterns, making the eastern portion ideal for crops like corn (the Corn Belt) and the western portion more suitable for wheat (the Wheat Belt).
