A “fun fact” that went viral a few years ago is the idea that there is an “ocean in the mantle”. This is UNEQUIVOCALLY not true. What happened is that there is a form of water trapped in the crystal lattice (chemical makeup) of crystals in earths mantle.

Ringwoodite can be as much as 1-3% water depending on the pressure con

Explaining The Ocean on Instagram: "The whale shark is the largest fish in the world, yet it’s often called a “gentle giant” of the oceans.

Their spotted skin patterns are unique to each individual, like fingerprints, making them easy to identify in the wild. Whale sharks are found in warm, tropical seas across the
