It is a well-known fact that Everest, the jewel of the Himalayan crown in Nepal, is the highest mountain in the world. This is one of the facts embedded in childhood, such as knowing that Neil Armstrong was the first person to walk. Month Or that Blue whale It is the largest animal ever lived.
Then you might be surprised to hear that other peaks are possible. Of earth Highest; it depends on how you measure them.
So what is the highest mountain in the world, judging by various parameters, such as the highest altitude, the highest from the base to the top, and the highest based on the farthest point from the center of the earth?
Located deep in the Himalayan Mahalanger Himal Subrange, Everest is arguably the most famous and fascinating of all the mountains on our planet. Everest, also known as Chomolungma, which means “Mother of the Goddess of the World” in Tibetan, was first scaled on May 29, 1953 by Nepalese Sherpa Tenzing Norgay and New Zealander Edmund Hillary, and then. About 4,000 people.. The mountain has also claimed the lives of more than 300 people since the record began to be held in 1922. According to the Guardian..
Researchers have measured Everest many times over the past few decades, but the latest assessments show that Announced in November 2021Place it at 29,031.69 feet (8,848.86 meters) above sea level. This is almost 5.5 miles (8.8 kilometers) high. It’s a pretty impressive height, but it raises the question: why use “above sea level” when determining the highest peaks in the world?
“We need a consistent baseline to ensure comparability of measurements,” Martin Price, professor and founding director of the Mountain Research Center at the University of the Highlands of Scotland, told Live Science.
“Historically and still, altitude is usually given as height above sea level,” Price told Live Science in an email. “But this needs to refer to the standard average sea level that must be defined. Sea level varies from region to region of the world and is changing for the following reasons: Climate change.. “
As a result, “elevation is now being measured in relation to the mathematically defined Earth geoid,” he said. Geoid is National Oceanic and Atmospheric Administration, “A model of global mean sea level used to measure accurate surface elevation.” This mean is used to determine the height of the mountains. This is the process by which an airplane needs to “fly back and forth on a series of parallel lines over a mountain and measure how much gravity is reduced at its peak.” GIM International.. These measurements, in combination with GPS readings, provide highly accurate elevation readings.
Therefore, all mountains are measured from sea level primarily for convenience and consistency, but what if the measurements were simply made from base to peak? Will Everest still at the top of the chart?
The answer is “no” in the mountains. The honor is given to Mauna Kea, Hawaii’s active volcano. Its peak is 13,802 feet (4,205 m) above sea level, which is less than half the height of Everest. National Geographic — Most of Mauna Kea is hidden beneath the surface of the sea. Measured from base to peak, Mauna Kea is 33,497 feet (10,211 m) high. United States Geological SurveyPlace your head and shoulders on Everest.
So should Mauna Kea be considered the highest mountain on the planet?
“It all depends on the perspective you take,” Price said. “If our planet doesn’t have oceans, there’s no dispute! You can compare it to the highest mountains in our solar system that don’t have oceans.”
Meanwhile, another candidate in Ecuador, Chimborazo, boasts the farthest mountain from the center of the globe.
Chimborazo is not the highest mountain in the Andes — not even in the top 30 — but its proximity to the equator makes all the difference. The Earth is not a perfect sphere, but technically an oblate spheroid, bulging along the equator. This is the result of the force produced by the rotation of the earth. As a result, there is a difference of 13.29 miles (21.39 km) between the planet’s polar radius (3,949.90 miles / 6,356.75 km) and the equatorial radius (3,963.19 miles / 6,378.14 km). NASA Goddard Space Flight Center..
Chimborazo is just one degree south of the equator, and the bulge of the earth is most noticeable.This geographical habit is at the top of Mt. Chimborazo 3,967 miles from the center of the earth, 6,798 feet (2,072 m) away from the center of the planet than the summit of Everest.
So which of these three candidates for the highest mountain should bring the first prize home?
Everest is the highest mountain above sea level, but Mauna Kea can certainly be claimed to be the highest mountain in the world (without considering sea level). It would be difficult to claim that Chimborazo is the tallest, but Price admitted, “it’s all a matter of perspective.”
Regardless of the mountain selected, its height will be thinner than that of Olympus Mons on Mars. Olympus Mons on Mars Solar system.. It is about 16 miles (25 km) high and is about 16 miles (25 km) high. According to NASA, Almost three times as high as Everest, 374 miles (601.9 km) in diameter, This is about the same distance between San Francisco and Los Angeles (383.1 miles / 616.5 km).
The asteroid Vesta, which is part of the asteroid belt 100 million miles from Earth, also has a collision crater called Rheasilvia. In the center of this crater The peak that scientists believe can be somewhere 12 to 15.5 miles (20 to 25 km) high. That is, it could be the highest mountain in the solar system.
