In all of human history, 12 people have reached the moon, while only three have reached the bottom of the deepest part of the ocean: the Challenger Deep. The deepest point- located within the Marina Trench, reaches nearly 10,000 meters deep- beyond the depths which light can reach.

Explanation:

94 percent of the ocean is still unexplored so thats it

that would be because of both gravity and friction. so     c
