1. PREFACE DEFINITIONSea are salt contained water that connectedwith the vast Ocean.Sea waters were a mixture from 96,5% offresh water dan 3,5% were other materials like salts, dissolved gasses, organicmaterials and unsolve particels . sea water physics are determined by those96,5%.HISTORYOceans, according to the history records, existsince 4,4 billions years ago, where it was hard acids and boilde over 100 °C because of the Earth’s heat and carbon dioxidein the atmosphere at that time. This leads to the quick weathering and were thecause of salts existed in the sea water.
At that time asteroids and meteoritesare smashing the earth surface and created a big wave. Tidal phase were somassive because of the moon that were so close to the earth. THE BEGINNINGAccording to the research, the beginning ofthe sea consist of several theories; butthe most common ones are after the earth start to cool down and decreasing ofvolcanic activity, beside at that time atmosphere were full of volcanic ash thatleads to the sun blocked by that ash and eventually form the first rain. Thewaters started to fill the crater from the meteorites and form the sea. Slowly, the carbon dioxide starts to vanishedand dissolved with the carbonate and form a carbonate calcium. Because of thatsun ray can went through. And cause an evaporation that decreased the watervolume. Weathering process keeps on going and washed to the sea by rain andincreased the salts in sea water.
At 3,8 billion years ago, Earth surface arestarting to look blue because of the ocean. Earth temperature are cooling downbecause the sea waters that absorb heat, but at that time there is no evidenceof live according to the fossil records.Life begin in the ocean, this theoriesstill remains a controversy until now. In the geological excavations in southAfrica at 1971 (predicted to be 3,2 to 4 billion years ago) shows a prehistoricbacteria that lived in the boiling mud under the sea.
This found support thattheory.
