Question

West of the lowlands is another major mountain system called the _______.

A) Rocky Mountains
B Appalachian Mountains
C) Sierra Nevada Mountains
D) Andes Mountains

Answer 1

The mountain system located west of the lowlands and referred to in the question is the Rocky Mountains, an extensive range stretching from New Mexico to Northern Canada.

Step-by-step explanation:

The mountain system to the west of the lowlands being referred to in the question is the Rocky Mountains. This major mountain system extends from New Mexico to Northern Canada and was primarily formed during the Laramide Orogeny in the Late Mesozoic and Early Cenozoic era. The Rocky Mountains differ from other mountain systems such as the Appalachian Mountains, whose formation involved multiple collisions including with the supercontinent of Gondwana, and the Sierra Nevada Mountains, which were also formed by subduction and have been deformed by extensional stress. Neither the Appalachian Mountains, which are mostly in the southeastern United States, nor the Sierra Nevada Mountains or the Andes Mountains, which are situated along the west coast of South America, match the description of being west of the lowlands like the Rocky Mountains do.
