The Appalachian Mountains are older and more eroded than the Rocky Mountains.
Okay~ Then///////// Similarity: They are located in the west. Differences: Rocky mountain is sharp, rocky peaks, but the Appalachian mountain is older, lower, then Rockies or Sierra Neveda. Also, Rocky mountain is higher then the Appalachian Mountain.
The Rocky Mountains are . . . well, rocky. The Appalachian mountains are more like hilly areas--not as sharply formed as the Rockies are.
Geologically speaking the Appalachians are older. The Rockies are an example of geological upheaval, while the Appalachians used to be a solid plain millions of years ago and eroded to become the mountains we have today.
The second longest mountain range in North America are the Appalachian Mountains. The first longest mountain range in North America are the Rocky Mountains.
The Rocky Mountains formed from the collision of the North American and Pacific plates, & uplifting areas of crust to form mountains. They started rising about 80 million years ago. Science, Continental - Continental where 100 million years ago where these two Earth crust collided together and after a while it started building up, and eventually became a mountain. The Rocky Mountains formed west to east, as based on geological evidence. The Appalachian Mountains formed from east to west, again based on geological evidence. The Appalachian Mountains are much older than The Rocky Mountains. The Rocky Mountains contains rock sediments proven to be from The Appalachian Mountains.
Pretty hard to say given that they are all the same chain of mountains that run down the East of the United States. They are all part of the Appalachian Mountains and are much older than the Rocky Mountains.
The Appalachian mountains are about 400-500 million years old and have thus been eroded down. The Rocky mountains are very young (they are still being built) and are therefore much higher and jagged as the forces of erosion have not yet had time to grind them away.
not much. the Appalachian mountains are old eroded mountains with not much left to them but the rockies have tall sharp jagged peaks that rise above the tree line some above 14,000 ft above sea level
The Appalachians are much older and have therefore been exposed to much more weathering and erosion.
95% of all tornadoes in the US occur in an area known as Tornado Alley, which includes parts of Texas, Oklahoma, Kansas, and Nebraska. Additionally, tornadoes can also occur in other regions of the US, such as the Southeast and Midwest.
