Learning a few amazing facts about Earth can remind humanity how lucky we are to call this planet home. One of the biggest of these mind blowing things about Earth is the fact that it's more than 4.5 billion years old. Then about 3.8 billion years ago, single cell organisms were born. About 230 million years ago, dinosaurs roamed the earth until they died and were replaced by early humans about 200,000 years ago. That's a lot of history.
Discovering things you didn't know about our planet can be an eye opening experience and could possibly bring about several life changing realizations that blow your mind. Understanding exactly how Earth works and came to be has inspired people for years. However, many humans don't stop to think about the ground they stand on or the water they drink since life is just too busy. Take a minute out of your day to embrace these interesting facts about Earth. They just might blow your mind.
The World's Longest Mountain Chain Is 40,389 Miles Long—And Is Located Underwater
The world's longest mountain range runs 40,389 miles around the world, and 90% of it is covered by ocean water. Called the Mid-Ocean Ridge, this underwater range was formed by magma rising to fill gaps that formed as Earth's plates shifted. Its mountains average a depth of 8,200 feet below the water's surface.
In comparison, the longest chain of mountains on land is South America's Andes, which is a paltry 4,350 miles long.
The Hottest Temperature Was 134 Degrees Fahrenheit And The Coldest Was -135.8 Degrees Fahrenheit
Death Valley holds the record for the hottest day ever, reaching 134 degrees Fahrenheit in 1913. This temperature beat a previous record in Libya after the World Meteorological Organization disqualified it for inaccuracy. On the other hand, the coldest day ever recorded was more than 135 degrees below zero, recorded in 2013 in Antarctica.
The Largest Volcanic Eruption Killed More Than 60,000 People, And The Strongest Earthquake Measured 9.5
In 1815, Mount Tambora in Indonesia erupted, creating a crater on its top 2,000 feet deep after it blew off 4,000 feet of mountain. It's believed 60,000 to 90,000 people were killed in the aftermath of the blast which was heard more than 1,200 miles away.
The most powerful earthquake ever recorded happened in 1960 when a 9.5 magnitude tremor shook Chile, destroying buildings, creating a series of tsunamis, and killing as many as 6,000 people.
Gravity Does Not Act The Same Everywhere On Earth
Because Earth is always moving, gravity is not the same all over and you would weigh slightly more at Earth's poles than at the equator. There are also places where gravity is extremely different, such as Hudson Bay in Canada. Scientists believe convection currents from Earth's mantle or Earth reacting to the pressure of ice on its surface being eliminated after it melts cause this.
