Using complete sentences, identify the three major mountain ranges in the United States, and describe the relative location of each range. What are the main differences between the eastern ranges and the western ranges?

Answer:

The Appalachian Mountains are in the eastern United States and extend from the Northeast toward the Southeast. The Rocky Mountains lie farther west, running north to south through the western interior of the country. The Sierra Nevada is farther west, mainly along the eastern side of California. The eastern Appalachians are older, lower, and more rounded than the western ranges, which are generally higher, more rugged, and have sharper peaks.
