Water molecules have A GREATER ATTRACTION for sodium and chloride ions than sodium and chloride ions have to each other.
This is because when salt is added to water, it dissolves, which depicts the level of the covalent bond of water is stronger by separating the ionic bond between sodium and chloride, otherwise, the salt would not have been able to dissolve.
I just answered this question from a different person but I like helping with science. This is from the water's breeze or air currents. This makes the climate mild while the inland is more extreme because it does not have the breeze. Hopefully this helps :D
I believe the correct answer is upwelling. Lets say we have producers such as plankton. well upwelling currents bring dead matter from the ocean floor up to the surface, creating plankton.
