Oceanographic Environment

The Earth Is Uniquely Favoured Among The Planets: It Has Rain, Rivers And Seas. The Large Planets (Jupiter, Saturn, Uranus And Neptune) Have Only A Small Solid Core, Presumably Overlain By Gases Liquefied By Pressure; They Are Also Surrounded By Enormous Atmospheres. The Inner Planets Are More Like The Earth. Mercury, However, Has Practically No Atmosphere And The Side Of The Planet Facing The Sun Is Hot Enough To Melt Lead. Venus Has A Thick Atmosphere Containing Little Water And A Surface That, According To Recent Measurements, May Be Even Hotter Than The Surface Of Mercury. Mars And The Moon Appear To Show Us Their Primeval Surfaces, Affected Only By Craters Formed By The Impact Of Meteorites, And Perhaps By Volcanoes. Only On The Earth Has The Repetition Of Erosion And Sedimentation The Colossal Hour Glass Of Rock Destruction And Rock Formation Run Its Course Cycle After Cycle And Produced The Diverse Surface That We See. The Mountains Are Raised And Then Worm Away By Falling And Running Water, The Debris Is Carried Onto The Low Lands And Then Out To The Ocean. Geologically Speaking, The Process Is Rapid. The Great Plateau Of Africa Is Reduced By A Foot In A Few Thousand Years, And In A Few Million Years It Will Be Near Sea Level, Like The Precambrian Rocks Of Canada And Finland. All Trace Of The Original Surface Of The Earth Has Been Removed, But As Far Back As One Can See There Is Evidence In Rounded, Water-Worm Pebbles For The Existence Of Running Water And Therefore, Presumably Of An Ocean And Of Dry Land.An Attempt Has Been Made To Make This Book Useful For Students, Research Scholars And Teachers. This Book Covers The Following Chapters: The Origin Of Ocean, Why The Sea Is Salt, The Ocean Basins, The Opening And Closing Of Ocean Basins, The Atmosphere And The Ocean, The Nature Of Oceanic Life, The Food Resources Of The Ocean, Oceanic Plants, Life On The Deep-Sea Floor, Plankton And Plankton Communities.
