Picture the landscape around your home. Do you see mountains? Hills and valleys? Maybe you see 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 explain 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. That’s because they are hard to reach and can have harsh climates.
