Answer:
The Appalachian Mountain range is located in both northeast and southeast of the United States.
Step-by-step explanation:
The Appalachians are a mountain range in eastern North America that extends from Canada into the United States. The Appalachians begin in Newfoundland, Canada, and extend all the way down to central Alabama in the southern United States, not far from the Gulf of Mexico. The Appalachians are between 160 and 480 km wide. Some foothills extend all the way to northeastern Mississippi, making the mountain range over 2,600 miles.
The system consists of several massifs and the mountains are on average 900 meters high. The highest mountain is Mount Mitchell (2,040 m) in North Carolina, which is the highest point in North America east of the Mississippi River.
