On land, the longest mountain range is the Andes of South America which is 7564 km (4700 mi) in length.\n\nBut if including underwater mountains, mid-Atlantic ridge would be the longest, extending 64,374 km (40,000 mi) from the Arctic Ocean to the Atlantic Ocean, around Africa, Asia, and Australia, and under the Pacific Ocean to the west coast of North America.\n\n(For the person that said the Himalayas, that would be the *highest* not the longest.)

I think your question is not correct. It should be world's longest beach, as beaches are  not meassured by its lenght and area. I have given below the longest  beach details. \n\nThere are several beaches which are claimed to be the "World's longest", the first being the natural beach at  Cox's Bazar, Bangladesh (120kms), is the world's longest natural sea beach (120 km). It is located 152 km south of Chittagong. \n\nOther long beaches are -\nFraser Island beach, 90 Mile Beach in Australia \n90 Mile Beach in New Zealand and \nLong Beach, Washington (which is about 30km). \n\nHowever for your information I would say - Cancun, Mexico, the world s largest beach resort destination in the world.-

if you consider a SEA and OCEAN to be the same, then it is the Pacific Ocean or formerly known as "the south sea(s)".  \n\nif you consider them different linguistically, ( as they are all bodies of water anyway ) then the "Mediterrainean Sea" is the largest sea on record.
