No, they are from rocks and minerals.
These salts are dissolved from the Earth rocks.
Salt is dissolved from the earth and transported by rivers in seas and oceans.
Rivers carry dissolved salts to the seas
Salts are dissolved from the earth and transported in seas and oceans by rivers; a small part of salts is formed from submarine volcanoes eruptions.
No. Most of the dissolved salts in the ocean come from the rivers emptying into the ocean. As the rivers flow from their sources to their mouths, they erode their channels and pick up salt and sediments from weathered rock, which are deposited into the ocean at their mouths.
Weathering of soil and rock to produce water soluble salts, which are carried to the sea by rivers that run into it.
The most important part of the sodium and calcium are dissolved from the earth salts and transported by rivers in seas/oceans.
salt in the ocean comes from dissolved minerals in rocks carried by streams and rivers, and especially from hydrothermal vents at the ocean floor. When water evaporates from the ocean, the minerals (salts) stay behind, so this salt doesn't go away, but only accumulates over time. Inland lakes generally have rivers leading in AND rivers leading out, so the water is constantly moving through, which keep them fresh.
Because of erosion, rotting vegetation, and other impurities dissolved in runoff water, rivers contain an average of about 12 grams of dissolved salts in each 100 kilograms of water. The rivers of the world send about 3 billion tonnes of salts to the ocean each year. Oceans also get some salt from volcanoes and hydrothermal vents on the ocean floor, but most come from rivers flowing into the oceans. The salts from rivers stay in the oceans when seawater evaporates during the water cycle, making the average amount of salt in seawater almost 300 times as much as in river water.
1. The most important part of the sodium and chlorine are dissolved from the earth salts and transported by rivers in seas/oceans.2. A small part of chlorine is originated from the eruptions of submarine volcanoes.
No, most of the dissolved salts in the oceans come from natural processes such as weathering of rocks and volcanic activity. Human activities do contribute some salts to the oceans, primarily through industrial and agricultural runoff, but they are not the primary source.
Common dissolved salts in water include sodium chloride (table salt), calcium carbonate, magnesium sulfate, and potassium chloride. These salts can come from natural sources, industrial processes, or human activities, and when present in high concentrations, they can impact water quality and taste.
