The deepest point on Earth is the Challenger Deep, located in the Mariana Trench in the Pacific Ocean. It reaches depths of approximately 36,000 feet (over 10,900 meters) below sea level. Discovered in the 1960s, this underwater abyss has fascinated scientists and explorers alike due to its extreme conditions and unique ecosystems. Many expeditions have attempted to explore Challenger Deep to understand more about its geological features and the life forms that inhabit such an inhospitable environment.
