Did you know that Earth used to have continents that no longer exist today? Millions of years ago, there were massive landmasses that have since disappeared, either sinking beneath the ocean or breaking apart to form new continents. One of these lost continents is called Zealandia, most of which is now submerged under the Pacific Ocean! There’s also a famous one called Gondwana, which eventually split into Africa, South America, Australia, and Antarctica. These changes happen because of plate tectonics, where Earth’s crust moves over time. It’s like a giant puzzle that keeps shifting, and we’re still discovering pieces of this ancient history!
