Ever heard of the Great Unconformity? Turns out, a massive chunk of Earth’s crust has been missing for ages, and scientists just cracked the case! Thanks to new tech, they found that glaciers during “Snowball Earth” scraped away up to 3-5 km of rock, sending it out to sea. That’s why there’s a weird gap in the rock record all over the world. Basically, Earth had a mega makeover and dumped the evidence! #Science #EarthScience #Geology
