Hello! It’s time for Fact Friday with Screenhog. I am Screenhog, and today we’re talking about the tallest mountain on Earth.
If the name that came to your head was “Mount Everest”, you’re right! But it’s not the only tallest mountain on earth. How is that possible? Well, it’s all in how you measure it.
The reason Mount Everest is called “the tallest mountain” is because it has the highest peak compared to sea level. However, if you measure it from the base of the mountain, the title of tallest mountain is no longer held by Everest. Instead, you’d have to go to Hawaii. The mountain of Mauna Kea is less than half the height of Everest when compared to sea level, but the base of the mountain extends 1 ½ kilometers into the sea. If you count that, Mauna Kea is over 1000 meters taller than Everest.
There is also a third way to measure the tallest mountain: the distance from the peak of the mountain to the center of the earth. Why does this make a difference? Because the earth is not a perfect sphere. It is not completely round. The distance from the North Pole to the South Pole is 42 kilometers less than the diameter of the Earth at the equator – in other words, it bulges out in the middle. So, what’s the tallest mountain close to the equator? Mt. Chimborazo in Ecuador. Of course, it was once an active volcano, so if it ever blows its top, who knows how long it will keep that title of “Tallest Mountain”.
