Credit: NASA. You may know that the oceans cover about 70 percent of the of Earth's surface, and that about 97 percent of all water on and in the Earth is saline—there's a lot of salty water on ... The water of the oceans is salty as it contains large amount of dissolved salts. Was this answer helpful?Ocean's salinity comes from dissolved minerals like sodium and chloride, washed from rocks by rivers and volcanic activity. Thus, sea water is 220 times saltier than the fresh lake water. What arouses the scientist's curiosity is not so much why the ocean is salty, but why it isn't fresh like the rivers and streams that empty into it. Further, what is the origin of the sea and of its "salts"? Simply put, water evaporates and leaves the sodium chloride, aka salt, behind. As the sun beams down on the ocean, it provides energy to water molecules and to the substances—such as salt—that ... Okay. "Because any salt there is on dry land gets rained on and washed into the sea. The water turns back into clouds later and rains on the land again, but the salt gets left behind in the sea. This has been happening for as far back as we can trace and over thousands of years it means the sea gets saltier and saltier. Figure 14.4: Ocean water is composed of many substances. The salts include sodium chloride, magnesium chloride, and calcium chloride. Perhaps the most important substance dissolved in the ocean is salt. Everyone knows that ocean water tastes salty. That salt comes from mineral deposits that find their way to the ocean through the water cycle ... Sea water is salty because it contains a large amount of salt dissolved in it. The salt present in ocean water is mainly sodium chloride, or the common salt we consume.

These include—you guessed it!—more salt. A similar reaction happens when underwater volcanoes erupt. The seawater surrounding the volcano reacts with the hot rocks of the volcano. Minerals and salts from those rocks dissolve into the ocean water. So now we know why ocean water is salty. True, the average adult body is 60 percent water, and that water is almost as salty as ocean water – but not quite, and the small difference in salinity makes a big difference. Drinking seawater or any kind of salt water increases the salinity of the blood. That actually draws water out of the cells, which ultimately shrivel and die, and the ...Consuming large amounts of salt water, however, can be fatal. When a dog ingests salt water, the excess salt draws water from the blood into the intestines, leading to diarrhea, vomiting, and ... Rain and other forms of precipitation fall on our planet as slightly acidic fresh water. As some of this water washes over the landscape, it physically erodes rocks and chemically breaks them down. It then carries salts from the rocks into rivers and other streams and deposits the salts in the ocean. Most inland bodies of water remain fresh ... The Dead Sea is often considered the saltiest place on earth. Its salt content is 33.7%! It has become so salty because it has no outlets, so water comes into the sea from rivers, but does not flow out again. Over the centuries, minerals have built up, water has evaporated, and the Dead Sea has become a place where no fish or animals can live. Understanding why the sea is salty begins with knowing how water cycles among its physical states: liquid, vapor, and ice. As a liquid, water dissolves rocks and sediments, and reacts with emissions from volcanoes and hydrothermal vents: this creates a complex solution of mineral salts in our ocean basins. Here's Why : The Salt Fresh water quenches thirst almost instantly, but salt water doesn't. New research shows how cells in the gut and on the tongue help the brain keep just the right ...Why is the sea salty?

Geological surveys show that the salt content of the oceans has remained virtually constant for hundreds of millions of ...Seawater is salty because it contains billions of years of mineral deposits brought to the oceans and seas by their tributary rivers. As rain falls it sinks into the ground, where it flows through the rocks and soil. It also runs over the top of land in the form of streams. These small, flowing bodies of water pick up dissolved minerals from ...Here, the water is chilled by arctic temperatures. It also gets saltier because when sea ice forms, the salt does not freeze and is left behind in the surrounding water. The cold water is now more dense, due to the added salts, and sinks toward the ocean bottom. Surface water moves in to replace the sinking water, thus creating a current.Why is the ocean salty. H.

At first this may not seem logical, as the oceans are salty and the rivers are not salty, so ...The short answer to the question “Why is the ocean salty?” is that water containing salts enters the ocean and has nowhere else to go. The water …Sea fish are not salty because their bodies have mechanisms to regulate the salt levels in their tissues and remove excess salt. They have specialized cells in their gills, called chloride cells, that produce an enzyme called gill Na+/K+ ATPase. This enzyme helps them rid their plasma of excess salt, which builds up when they drink seawater.Our World: Why Are Oceans Salty? Description.

Dissolved minerals from hydrothermal vents and underwater volcanoes also contribute to the saltiness of the ocean. It is affected by such factors as melting of ice, inflow of river water, evaporation, rain, snowfall, wind, wave motion, and ocean currents that cause horizontal and vertical mixing of the saltwater. The saltiest water (40 o/oo ) occurs in the Red Sea and the Persian Gulf, where rates of evaporation are very high. Icebergs form from a variety of processes, yet even though they may be found floating in salty seawater, they are primarily made of freshwater.
