Most geologically young mountain ranges on the Earth's land surface are associated with either the [[Pacific Ring of Fire]] or the [[Alpide belt]]. The Pacific Ring of Fire includes the [[Andes]] of South America, extends through the [[North American Cordillera]], the [[Aleutian Range]], on through [[Kamchatka|Kamchatka Peninsula]], [[Japan]], [[Taiwan]], the [[Philippines]], [[Papua New Guinea]], to [[New Zealand]].<ref>{{cite web|url=https://www.thoughtco.com/ring-of-fire-1433460 |first=Matt|last=Rosenberg|publisher=ThoughtCo.|title= Ring of Fire|date =22 December 2018}}</ref> The Andes is {{convert|7000|km|mi|0}} long and is often considered the world's longest mountain system.<ref>{{cite book|title=The Pearson General Knowledge Manual|year=2012|page=A-36|first=Edgar|last=Thorpe|publisher= Pearson Education India}}</ref>

The Alpide belt stretches 15,000 km across southern [[Eurasia]], from [[Java]] in Maritime [[Southeast Asia]] to the [[Iberian Peninsula]] in [[Western Europe]], including the ranges of the [[Himalayas]], [[Karakoram]], [[Hindu Kush]], [[Alborz]], [[Caucasus_Mountains|Caucasus]], and the [[Alps]].<ref>{{cite book|title=Furnace of Creation, Cradle of Destruction|url=https://archive.org/details/furnaceofcreatio00ches|url-access=registration|first=Roy|last=Chester|page=[https://archive.org/details/furnaceofcreatio00ches/page/77 77]|year=2008|publisher=AMACOM Div American Mgmt Assn|isbn=9780814409206}}</ref> The Himalayas contain the highest mountains in the world, including [[Mount Everest]], which is {{convert|8848|m|ft}} high.<ref>{{cite news|url=http://news.bbc.co.uk/2/hi/south_asia/8608913.stm|publisher=BBC|title=Nepal and China agree on Mount Everest's height|date=8 April 2010}}</ref>

Mountain ranges outside these two systems include the [[Arctic Cordillera]], [[Appalachian Mountains|Appalachians]], [[Great Dividing Range]], [[East Siberian Mountains|East Siberians]], [[Altai Mountains|Altais]], [[Scandinavian Mountains|Scandinavians]], [[Qinling]], [[Western Ghats]], [[Vindhya Range|Vindhyas]], [[Byrranga Mountains|Byrrangas]], and the [[Annamite Range]]. If the definition of a mountain range is stretched to include underwater mountains, then the [[Ocean Ridge]] forms the longest continuous mountain system on Earth, with a length of {{Convert|65000|km|mi|-2}}.<ref>{{cite web|url=http://oceanservice.noaa.gov/facts/midoceanridge.html|title=The mid-ocean ridge is the longest mountain range on Earth|date=11 Jan 2013|publisher=US National Oceanic and Atmospheric Service}}</ref>
