The longest mountain range is around 65,000 kilometers (40,400 miles) long-and 90 percent is under the ocean! Called the Mid-Ocean Ridge, it wraps around the globe like the seams of a baseball. As a whole, 24% of the Earth’s land mass is mountainous.Ī few mountains are isolated summits, but most occur in huge mountain ranges. Using these definitions, mountains cover 33% of Eurasia, 19% of South America, 24% of North America, and 14% of Africa. Elevation of at least 300 meters (980 feet), with a 300 meters (980 feet) elevation range within 7 kilometers (4.3 miles).Elevation of at least 1,000 meters (3,300 feet), with a slope greater than 5 degrees.Elevation of at least 1,500 meters (4,900 feet), with a slope greater than 2 degrees.Elevation of at least 2,500 meters (8,200 feet).The UN Environmental Programme’s definition of “mountainous environment” includes any of the following:
Elevation, volume, relief, steepness, spacing and continuity have been used as criteria for defining a mountain. There is no universally accepted definition of a mountain. Volcanoes are formed when a plate is pushed below another plate, or at a mid-ocean ridge or hotspot. Many of the greatest mountain ranges of the world have formed because of enormous collisions between continents. When two slabs of the earth’s crust smash into each other the land can be pushed upwards, forming mountains. The Earth’s crust is made up of 6 huge slabs called plates, which fit together like a jigsaw puzzle. Mountains are formed by slow but gigantic movements of the Earth’s crust (the outer layer of the Earth). Simply put, they are the result of tectonic forces or volcanism. Thanks to modern geology, we now know the true story of how mountains are formed. A global plot against humanity? Not so fun.A mountain is a large landform that stretches above the surrounding land in a limited area, usually in the form of a peak. A superstition or conspiracy theory you're interested in (Tread lightly here, though.A story about a strange or funny encounter with a celebrity.You're really good at rollerblading, chess, or a sport.What is something fun, exciting, or unexpected about you? Fun facts are great because they usually get people thinking about their own quirks and memories. How you "found out" about Santa Claus or The Tooth Fairy.The weirdest coincidence you've ever experienced.The one type of food you would eat for the rest of your life if you had to pick."I am always 20 minutes early for everything.") Something you learned late in life (like how Goofy is a cow and not a dog?!).The color of your first bedroom (my nephew used to ask this when he was 3 years old and I think it's a great question).A formative memory or your earliest memory-especially if it pertains to the job.The first book you ever remember reading.A prized object you carried everywhere with you as a child (extra points if you still have it!).Your hometown, especially if it’s vastly different from your current location.Did you win the best laugh? (*Don’t use it if it makes you seem arrogant or conceited.) What makes you stand out from the rest of the candidates?
