The Andes Mountains in South America are
the longest mountain chain in the world. The Andes stretch
4,500 miles from the southern tip of the continent to the
Caribbean coast of Venezuela. Their average height is 10,000
feet. Mount Aconcagua, located in Argentina, is the highest
mountain in the Western Hemisphere. Mount Aconcagua is
22,834 feet high.
Geographers believe that young mountains
are high and old mountains are low. The Andes Mountains are
about 20 million years old, but are still considered young.
They were created when plates (giant pieces of the earth's crust)
pushed against each other. The two plates, the continental
plate on the east and the Pacific plate on the west, were forced
toward each other. The soft limestone and sandstone rocks
were folded upward. This formed a long, north-south
wall. Earthquakes and volcanoes also played a part in the
formation of the Andes Mountains and still occur periodically
Some people consider the Andes Mountains
to be the most valuable mountains in the world because of their
mineral resources. Gold, silver, platinum, copper, tin and
iron are mined from the Andes.
