Describe some of the reasons for exploring the mid-cayman ridge.

A key purpose of NOAA’s Ocean Exploration Initiative is to investigate the more than 95 percent of Earth’s underwater world that until now has remained virtually unknown and unseen. Such exploration may reveal clues to the origin of life on Earth, new knowledge about the forces that cause natural hazards such as volcanoes and earthquakes, cures for human diseases, answers about how to achieve sustainable use of resources, and information to protect endangered species. 

One of the reasons to exploring the mid-Cayman ridge is that it can be used as a way to look into the past. We can look at how life may have existed before photosynthesis (even though such theories are against my religious beliefs and all common sense evidence). It lets us look into the past about 3.5 “billion” years ago. It's a key to understanding how life began on Earth, and it might point to how life may exist on other planets.

It is Osmosis and diffusion.
