Ocean Formation How did the oceans form??
Formation of the Ocean Earth is approximately 4.6 Billion Years Old Oceans formed 2 possible ways: –Comets –Volcanism
Comets Comets hit the Earth and released water The water filled the ocean basins over geologic time
Volcanism Volcanoes release Water Vapor, Carbon Dioxide and other gases Water vapor condensed to form water droplets that formed the oceans
Chemical Properties of Seawater 96.5% Water 3.5% Dissolved salts –NaCl is most abundant
Salinity –Measure of the amount of dissolved salts in seawater –Expressed in ppt (Parts per thousand) 35 ppt
How Does the Water Become Salty??? Volcanic gases contain chlorine and sulfur dioxide which dissolve into water Weathering of rocks and minerals
Salt Removal Sea Spray Evaporate Formation –Water evaporates and salt is left behind
Desalinization Processes that turns saltwater into freshwater Distillation –Water heated and evaporated –Water vapor cooled and condensed as freshwater
Reverse Osmosis –Seawater pressed through semi permeable membrane that allows water, not NaCl to pass through
Why would we want to remove salt? Humans need freshwater to survive Of the 3% of freshwater, most is unavailable to us! (glaciers) In case of drought conditions, water would still be available
Negative Effects Environmental concerns –Loss of habitat, waste (salt) disposal Costs Money and uses Energy Greenhouse gas emissions
Ocean Formation How did the oceans form??.
Ocean Water (63) Oceans are important sources of food, energy, and minerals. Energy sources such as oil and natural gas are found beneath the ocean floor.

Desalination Desalination is the process of converting saline (salt) water into freshwater.
How would you describe the composition of the ocean?

Chemical Oceanography: Salinity. What is Salinity? A measure of the amount of salt in seawater, measured in parts per thousand (ppt) or percentage (%o).
The Oceans Composition. The Oceans There are five main oceans: –Pacific, Atlantic, Indian, Arctic, Antarctic.
Earth Science: 15.1 Ocean Water and Life
Or Water, Water Everywhere. The Water Planet More than 70% of Earth’s surface is covered with water. Because of this, Earth is called ‘the Water Planet.’
Salinity. “Salinity” is defined as the amount of dissolved solids in the water. The most common dissolved solid is sodium chloride, commonly known.

Physical Oceanography Section 2: Seawater
OCEAN FORMATION How did the oceans form??. Earth is approximately 4.6 Billion Years Old Earth is a closed system with water never leaving our planet.

Salt Water vs. Fresh Water A closer look. Salt Water vs. Fresh Water Approximately 97% of the Earth’s water is salt water in seas and oceans. Only 3%
Seawater Seawater is a solution of about 96.5% water and 3.5% dissolved salts. The most abundant salt in seawater is sodium chloride (NaCl). Most elements.
