Final answer:
Mountain ranges on Earth do not occur randomly; they tend to occur in particular patterns due to the movement of continental masses. The formation of mountains is usually a result of two continental masses moving on a collision course and causing the Earth to buckle and fold.
Step-by-step explanation:
Mountain ranges on Earth do not occur randomly; they tend to occur in particular patterns. They can occur in clusters, linear chains, arcs, or other formations. The formation of mountains is usually a result of two continental masses moving on a collision course, pushing against each other and causing the Earth to buckle and fold, raising folds to heights of many kilometers. For example, the Alps were formed by the African plate colliding with the Eurasian plate.
