The Indian Ocean is polluted
480cm a year depending on the location.
It is very difficult to measures the precipitation in the ocean. This is because the ocean is far too large.
Waste is poured into the ocean water, and it turns into rain, making it polluted rainwater.
Precipitation over the ocean in the water cycle accounts for about 45 of the total global precipitation.
The humans started littering and it polluted the water.
precipitation
Most precipitation falls into the ocean because about 71% of the Earth's surface is covered by water. The water cycle drives the movement of water from the ocean to the atmosphere and back again through evaporation, condensation, and precipitation, resulting in a large amount of rainfall in the ocean.
The spill is in the Gulf of Mexico, which is a body of water off the Atlantic ocean.
Technically all oceans are in some way or another polluted; the ocean is one gigantic mass of salt water, and the currents will move harmful chemicals around in it, just as they will with nutrients. Also since almost every landmass in the world is occupied by humans, and the majority of our species pollut in some manner of another. It is very difficult to not have the majority of oceans be polluted in some way.
