ELI5: Why water in the Caribbean is so clear while it is so cloudy further north?
gpt
There is little to no water surface plant life in them like algae, as the climate does not support it, which is part of it. This allows for scattering of light off of the white sandy beaches formed by the coral reefs, making it appear clearer. The other part is the cyclical nature of pollution that occurs much more frequently in the north than it does in the Caribbean.
