Allow me to roll out a cliché and say that here at TreeHugger, every day is Earth Day. Tips on going green and sustainable design and treehugging in general are business as usual; our modus operandi 24/7. But who would we be to let such a momentous day as April 22 pass without some fanfare? So with that in mind, here’s some praise for the planet, glory for the globe, an all-around high-five highlighting some randomly remarkable features of this wild world we’re so lucky to call home.
1. Earth plays host to deadly, exploding lakes
Why should science fiction and horror movies have all the fun? Earth is pretty dramatic too. We’ve even got exploding lakes. In Cameroon and on the border of Rwanda and the Democratic Republic of the Congo there are three crater lakes – Nyos, Monoun and Kivu – which sit above volcanic earth. The magma below releases carbon dioxide into the lakes, and the gas can escape to form a limnic eruption, potentially killing everything nearby. Around Kivu Lake, geologists have found evidence of massive biological extinctions about every thousand years.
2. The planet is covered in stardust
Every year, 40,000 tons of cosmic dust falls upon our planet. It’s not something we notice, but eventually all that dust, which is made of oxygen, carbon, iron, nickel, and all the other elements, finds its way into our bodies. We are stardust.
3. You can’t keep a good planet still
While we may feel like we’re standing still, of course, we are not. We’re actually spinning wildly and flying through space! It's a wonder life seems so calm. Depending on where you are, you could be spinning at over 1,000 miles per hour (though those on the North or South poles would be still). Meanwhile, we’re moving around the sun at a zippy 67,000 miles per hour. Whoosh.
4. It has some really cold spots
We’re talking really, really cold. A few hundred miles from the Arctic Circle is the town of Oymyakon, Russia, which in 1933 earned the title as the coldest place on Earth when the temperature dropped to -90 F. It is so cold here that people don’t turn their cars off and must heat the ground with a bonfire for days before in order to bury their dead. During the winter, the temperature averages -58 F.
5. And others that are as hot as Hades
On the other end of the mercury, Death Valley plays home to the hottest temperatures recorded: the hottest on the planet being 134 F on July 10, 1913. That was not a good week in the desert; temperatures reached 129 F or above on five consecutive days. More recently, the summer of 2001 saw 100 F for 154 consecutive days, while the summer of 1996 was bestowed with 105 days over 110 F and 40 days when the mercury reached 120 F.
6. The high highs are really high
At 29,028 feet above sea level, Mount Everest is the highest place on Earth when measured by sea level. But if you measure height based on the distance from the center of the planet, Mount Chimaborazo in the Andes Mountains in Ecuador takes the prize. Although Chimaborazo is about 10,000 feet shorter (relative to sea level) than Everest, this mountain is about 1.5 miles farther into space because of the equatorial bulge.
7. And the low down is deep
The lowest point on Earth is the Mariana Trench in the western Pacific Ocean. It reaches down about 36,200 feet, nearly 7 miles, below sea level.
8. The planet has rocks that scoot themselves
In a remote stretch of Death Valley, a lakebed known as Racetrack Play plays home to one of the natural world’s more compelling mysteries: Rocks that sail across the bed of the lake, propelled by nothing that anyone can see. It’s a puzzle that has long-stumped scientists, and has never actually ever been seen in action, save for the long meandering tracks left behind in the mud surface.
9. And dunes that sing
Around 30 places across the planet have sand dunes that sing and croak, creating low droning music that lands somewhere between chanting monks and a swarm of bees. From the Gobi Desert and Death Valley to the Sahara and Chilean desert, the source of the sounds has long remained a mystery, although there are a number of theories explaining the sonic phenomena, it remains a hotly debated topic.
10. The world below is a giant, mysterious thing
We think we’re so fancy with our terrestrial lives, but you should see what’s going on down in the coral reefs. It is there in which exists the most species per unit area of any of the planet's ecosystems, even more than the rain forests. And while the reefs are comprised of tiny individual coral polyps, together they form the largest living structures on Earth, even visible from space.
11. There’s a sweet spot for lightning
Every night in northwestern Venezuela, where the Catatumbo River meets Lake Maracaibo, a thunderstorm occurs. And not just a passing show, but a storm that can last up to 10 hours and averaging 28 lightning strikes per minute. Known as Relámpago del Catatumbo (the Catatumbo Lightning) it can strike as many as 3,600 bolts in an hour. Every night!
12. And we don’t know the half of it
While oceans cover around 70 percent of the planet, we’ve only explored some 5 percent of them. In a similar vein, scientists estimate that there are anywhere between 5 million and 100 million species on Earth, but … we have identified only about 2 million of them. We think we know it all, but there is so much left to discover. What a wonderful world!
