Rispondi Salva. The concentration of salt in seawater (salinity) varies with temperature, evaporation, and precipitation. While the Atlantic ocean is losing water and becoming saltier, it is giving water to the Pacific ocean, making it less salty. … Lv 6. 3. This very-slightly salty water flows into the oceans and seas. You must be curious about how much salt is needed to make this vast sea salty. How are they different from fresh water sources, how are they same, and how did the ocean get this way? But have you ever wondered why the ocean water is salty ? The most dilute lake in the world is Lae Notasha, located near the crest of the Oregon Cascade in Oregon, United States. In water, these are sodium, magnesium, and potassium cations, and chloride, sulfate, nitrate, and carbonate anions. So why is the sea salty? Pertinenza. When rain falls, it weathers rocks, releasing mineral salts that separate into ions. More recently, ions from eroded rocks entered the ocean as rivers drained into the sea. Rainfall and evaporation are difficult to measure accurately, particularly over the ocean where 78% of rain falls.. However, being far from the sun, the ocean surface is completely frozen. On the other hand, the salts and minerals are carried away by the rivers in to the ocean continuously. 14 risposte. The water in your tap isn’t salty (if you’re lucky). If you’re wondering what the exact salts that make the ocean salty are, the answer is chloride and sodium. Rivers and lakes aren’t salty. However, many questions arise. To understand why the seas are so salty, look no further than the water cycle. Why is the sea salty? What happens is,that,when a river flows into the ocean it carries some land with it. Why? Salty water affects the movement and composition of ocean water as saline water is denser than fresh water. You might think the ocean would become increasingly salty over time, but part of the reason it does not is because many of the ions in the ocean are taken in by the organisms that live in the ocean. So where does it all come from? Rivers and lakes aren’t salty. Oceans have been around a very long time, so some of the salts were added to the water at a time when gases and lava were spewing from increased volcanic activity. The ocean is vast, unpredictable, and…salty. Finally, we tell some of the old folk-tales that different cultures used to tell to explain why the sea is salty. As the rain appears and water flows over the land, the water dissolved salt out of the rain, it just washes the salt into the streams then after rivers and at last, carries the salt to the sea and after that, the salt stays in the sea as no water flows out of the sea. Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. On the other hand, a water droplet and its salts may remain in the ocean for 100-200 million years. Why is Seawater Salty? The reason the sea is salty is because it is very old. If the minerals associated with a lake don't contain much sodium, the water won't be very salty. Where does salt come from? It also affects elements of water like humidity, temperature, and solar insolation. Salt in the sea, or ocean salinity, is mainly caused by rain washing mineral ions from the land into water. This ocean is deep enough to cover the whole surface of Europa and contains more liquid water than all of Earth's oceans combined. But isolated bodies of water, however, can become extra salty.
