Imagine the landscape where you live. Does it have mountains, hills and valleys, flat farmland, or rocky shorelines?
The United States is a big country with many diverse regions. Landforms such as mountains, valleys, and plains (flat lands) are part of what makes each region distinct from other places.
Landforms also help to determine where people live and how they use the land. Most farmers want to live in the fertile plains and valleys where crops grow well. Mountainous areas are often the last regions to be settled because they are hard to reach and can have harsh climates.
