Mountains exist on every continent and even beneath our great oceans. Mountains cover one-fifth of the earth's land surface, and are present in 75% of the world's countries.
Some of the highest mountains are at the bottom of the sea. Hawaii is at the top of a volcanic mountain in the Pacific Ocean. More than half the mountain is below water.
The world's longest mountain system is known as Ocean Ridge, which is a chain of mountains that runs on the seafloor of five oceans around the world; it has a length of 65,000 kilometres (40,400 mi), and the total length of the system is 80,000 kilometres.
The tallest known mountain in the solar system is Olympus Mons, located on Mars. It is a little under three times as tall as Mount Everest.
The highest 14 mountains in the world are all found in the Himalayan range.
It is estimated that one eighth of the world's population lives in mountainous zones. The Alps are the most densely populated mountain area in the world.
The Andes, which runs more than 7,000 kilometres, is the longest mountain range on land while the Himalayas are the highest and the youngest.
The Himalayas are geologically alive! The southern front moves up approximately 20 mm a year and it is estimated that in 10 million years time, the Himalayas will have moved approximately 1,500 km into Asia.
