Earth's 10 Hidden Secrets

WRITTEN BY: Xuan Pham

The Earth is estimated to be about 4.5 billion years old. Relative to this impressive record, human civilization is but a blink of an eye. If Earth's history was shortened into a 24-hour day, humans would have appeared somewhere around the last 2 minutes - that's how new we are to this planet.

Given that we have only known Earth for a short while, it's impressive the amount of information we've been able to glean from geological and archeological records. But rest assured that we still have many of Earth's secrets to uncover. For example, scientists think there's a massive underground ocean trapped miles beneath the Earth's surface inside the ringwoodite rock. As if that wasn't enough, they think the volume of water trapped here is enough to replace all of Earth's oceans three times over.

Scientists are ‘unearthing' more and more curious facts about Earth every day. Watch the video and find out something you may or may not have known about your home planet!
