At the bottom of the ocean there are volcanoes



Most modern volcanoes are located within three main volcanic zones: Pacific, the Mediterranean and the Atlantic-Indonesian. As the results of the study of the geological past of our planet, submarine volcanoes in its scope and volume comes from the bowels of the earth ejected far superior volcanoes on land. If land annually from 20-30 volcanic eruptions comes to an average of a half cubic kilometers of molten magma per year, over the same period of the submarine volcanoes erupting material is 12-15 times greater.

Life in the surface waters of the ocean, from which depends on the amount of greenhouse gases absorbed by the oceans, supported by active undersea volcanoes. This happens because the submarine volcanoes supply phytoplankton iron compounds needed for photosynthesis.
