What are the difference between the Appalachian mountains and the coastal plan?

The Appalachian Mountains are a series of rugged, old mountain ranges that run from Canada to Alabama, characterized by rolling hills, deep valleys, and high elevations. In contrast, the Coastal Plain is a flat, low-lying region that extends from the Atlantic Ocean inland, featuring gentle slopes and fertile land. The Appalachian Mountains are known for their biodiversity and complex ecosystems, while the Coastal Plain is often associated with agriculture and coastal wetlands. These distinct geographical features lead to different climates, ecosystems, and human activities in each region.
