Why is ocean water salty class 7?

The oceans cover 70 percent of the earth’s surface and contain around 1.5 trillion tons of salty water. In order to maintain the salt content of earth’s oceans, about 50,000 dams and pumping plants crisscross the world’s seas. The phenomenon of ocean water salinity class 7 is mainly caused by the natural evaporation of seawater and the transportation of salts to the ocean by rivers, glaciers, and the atmosphere.

Why is ocean water salty?

The specific measure of salinity is called “salinity” or “salinity concentration”. The overall salinity of the earth’s oceans is about 35 grams of salt per kilogram of water. The salinity of ocean water is similar to that of human tears.

What makes ocean water salty?

The main reason for the saltiness of the ocean is that it is located in the tropics. The water evaporates when it is heated by the sun, concentrating the salt in the water, which is then deposited on the ocean floor.

Why is seawater salty class 7?

The average concentration of dissolved salts in seawater is about 3.5 grams per liter and the saltiest ocean water is almost 3.7 grams per liter of salt. In other words, ordinary seawater has about 35 grams of salt per kilogram of water. The food that ocean plants feed on has a different salt concentration than the seawater. To allow these plants to grow, they need a salty environment. The oceans also contain other nutrients, such as potassium and phosphorus.

Why is the water in the ocean salty?

The ocean is salty because it contains salts that are dissolved in it. These salts include nutrients for marine plants and animals. Also, some minerals contained in the ocean make it salty. Sodium chloride (salt) is the most common type of dissolved salt in the ocean.
