Incredible Facts You Never Knew About Our Planet
Alien worlds may seem mysterious, but have you ever stopped to think about our own? There are so many unexplored areas of our world and species we haven't even discovered yet. Ready to have your mind blown? Here's 3 amazing facts about Earth that you never knew (you'll have to watch the video to get the rest!):
1. The Earth is constantly farting
Did you know that the Earth loses a lot of its mass due to gases like hydrogen escaping through the atmosphere? Because hydrogen is so light, it's able to leave the atmosphere at a rate of 3 kg per second, which adds up to about 95,000 tonnes a year.
2. Our oceans are a mystery
Get this: we've only discovered about 5% of the Earth's oceans. And since oceans cover 70% of the planet, this means that we've only uncovered a small fraction of the place we call home. What's even crazier, is that the deepest depth — the Mariana Trench — is measured at almost 11,000 meters. For context, if you put the base of Mount Everest at the bottom of the trench, the peak would still be 1.6 km underwater.
3. The oldest animal is a sponge
That's right, the oldest living animal species is the Antarctic glass sponge. It's estimated to be more than 15,000 years old, which means this species has been around longer than the pyramids and the wheel! If that doesn't make you feel weird, how about the Pando tree colony that consists of 40,000 genetically identical trees? The species located in Utah is estimated at being 80,000 years old and is considered all one tree. If you want to learn more insane Earth facts, check out the video above!
