They inferred that the Appalachian Mountains have been eroding for millions of years.
The Appalachian Mountains region in eastern North America is known for its old, rounded mountains that were formed hundreds of millions of years ago. These mountains were once taller but have been eroded over time, giving them their distinctive rounded appearance.
The Appalachian Mtns are very, very old, highly eroded folded mountains.
The Rocky Mountains are taller than Appalachian Mountains and has sharp pointy peaks. The Rocky Mountains are taller.They Both have eroded. The Appalachian Mountains are older and shorter than rocky mountains.
The Appalachian Highlands are old, eroded mountains (the oldest in North America) ranging from eastern Canada to western Alabama
The Appalachian Region in eastern North America is known for its old, rounded mountains, such as the Blue Ridge Mountains and the Great Smoky Mountains. These mountains are considered some of the oldest in the world, with their rugged peaks eroded over millions of years to create their distinctive rounded appearance.
The Rocky Mountains are taller than Appalachian Mountains and has sharp pointy peaks. The Rocky Mountains are taller.They Both have eroded. The Appalachian Mountains are older and shorter than rocky mountains.
They both have been greatly eroded over time.
The Appalachian Mountains are mountains that are only about 30,000 ft in elevation, they are much older than the Rockey Mountains, so they have been weathered and eroded in witch gives them rounded tops and there shorter elevation.
the peaks become weathered and eroded. that's why the peaks are rounded.
At the link below see some pictures. Notice that the mountains are not very tall. That is because they are old and have been eroded.
The Appalachian mountains are older and composed of softer rocks, like sandstone and shale, which are more susceptible to erosion compared to the rocky mountains, which are younger and made of harder, more resistant rocks like granite and quartzite. Additionally, the Appalachian region receives more precipitation, which accelerates the erosion process.
