Geology is more than just studying rocks. With advancing technology, scientists are reconstructing Earth’s makeup in greater detail, uncovering how landscapes and oceans looked millions of years ago. A fascinating geological event is the desiccation of seas, where bodies of water are cut off from the open ocean and slowly evaporate, leaving behind vast salt deserts. Famously, the Mediterranean Sea dried up about 6 million years ago and only refilled during the dramatic Zanclean flood, after remaining mostly dry for nearly 700,000 years.
