1. Challenger Deep is the deepest known point in the ocean, at 35,814 feet below sea level. In 1960 , Jacques Piccard and Don Walsh rode down in the Trieste and became the first people to visit the Challenger Deep.

Did you know that the pressure at Challenger Deep is over 1,000 times greater than at sea level? That’s like having a huge elephant standing on your small toe! This immense pressure makes it incredibly challenging for submersibles and scientists to explore the depths. Despite this, advancements in technology are allowing us to learn more about this mysterious part of our planet. In recent years, deep-sea exploration has led to groundbreaking discoveries, including new species of organisms that thrive in the extreme conditions of the Mariana Trench. These unique creatures have adaptations that allow them to survive in high-pressure environments, providing insights into evolution and potential applications in medicine and biotechnology. Who knew the deep ocean was like a treasure chest of secrets just waiting to be discovered?
