The Rockies vary in width from 110 to 480 kilometres (70 to 300 miles). The Rocky Mountains contain the highest peaks in central North America. The range's highest peak is Mount Elbert in Colorado at 4,401 metres (14,440 feet) above sea level. Mount Robson in British Columbia, at 3,954 m (12,972 ft), is the highest peak in the Canadian Rockies.
The Alps extend in an arc from France in the south and west to Slovenia in the east, and from Monaco in the south to Germany in the north. The Alps are a crescent shaped geographic feature of central Europe that ranges in an 800 km (500 mi) arc (curved line) from east to west and is 200 km (120 mi) in width.
While smaller groups within the Alps may be easily defined by the passes on either side, defining larger units can be problematic. A traditional divide exists between the Western Alps and the Eastern Alps, which uses the Splügen Pass (Italian: Passo dello Spluga) on the Swiss-Italian border, together with the Rhine to the north and Lake Como in the south as the defining features.
Physiographic world map with mountain ranges and highland areas in brown, pink, and gray. This is a list of mountain ranges on Earth and a few other astronomical bodies.First, the highest and longest mountain ranges on Earth are listed, followed by more comprehensive alphabetical lists organized by continent.
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny . [ 1 ]
The range is older than the other major mountain range in North America, the Rocky Mountains of the west. Some of the outcrops in the Appalachians contain rocks formed during the Precambrian era. The geologic processes that led to the formation of the Appalachian Mountains started 1.1 billion years ago.
The rocky cores of the mountain ranges are, in most places, formed of pieces of continental crust that are over one billion years old. In the south, an older mountain range was formed 300 million years ago, then eroded away. The rocks of that older range were reformed into the Rocky Mountains.
Unlike the high mountain ranges found in places like the Rockies (highest peak 4,401 m (14,439 ft)), the European Alps (highest peak 4,808 m (15,774 ft)) or the Himalayas (highest peak 8,848 m (29,029 ft)), the Australian Alps were not formed by two continental plates colliding and pushing up the Earth's rocky mantle to form jagged, rocky peaks ...
