Picture the landscape where you live. Are there mountains? Hills and valleys? Maybe you see flat farmland or rocky shorelines.
The United States is a big country with many different regions. Landforms such as mountains, valleys, and plains (flat lands) are part of what makes each region stand out from other places.
Landforms also help to shape where people live and how they use the land. Most farmers want to live in fertile plains and valleys. That’s because crops grow well in those places. Regions with a lot of mountains are often settled last. Those areas are hard to reach and can have harsh climates.
