A mountain is a land form with high elevation. The mountain range is a group of mountains that are closely related in shape, structure, or age.
A mountain range is a series of connected mountains, while a mountain system is a larger area that includes multiple mountain ranges and associated geographical features. The Rocky Mountains exemplify a mountain range, whereas the Pacific Mountain System encompasses multiple ranges like the Sierra Nevada and Cascade. The main difference lies in the scale and grouping of these formations.
