Hello how may I help you? I'm qriting a research paper, and I need to know what the deepest point on Earth is. That would be the Challenger Deep in the Mariana Trench Cool. How deep is it? It is 10,994 meters below sea level Has anyone evwr been there? It was explored in 1960 Did they scuba dive down to it, or did they need a submarine? It was done by sonar mapping. It's too deep for anyone to scuba dive Thanks! I'm totally getting an A on this paper! Good Luck!
