Why seawater is salty give reason?
The oceans which cover 70 percent of the earth’s surface, are a natural source of salt. It is estimated that the average amount of salt in the ocean is approximately 3.5 grams per liter of water (or 35 grams per gallon). The salt content in the oceans is dependent on the amount of freshwater that flows into it. As rivers and lakes evaporate, they leave behind minerals, including salt, in the form of deposits. Over time, the deposits can build up and create
Why is seawater salty give reason?
About 70% of the water in the oceans is salty, enough to make a cube of pure water weigh about 3.5 tons! The oceans are salty because of all of the minerals they hold. The oceans contain about 70% of the salt in the world’s water. The remaining 30% is locked up in the land. Even so, the oceans contain about 20 times more salt than the amount of freshwater on the earth’s surface.
Why is seawater salty and why is it warm?
There are two main ways seawater gets salty: absorption and evaporation. Absorption is the process by which water absorbs minerals from the surrounding rock. This salty water is then pumped to the surface. The process of evaporation removes the excess water from the ocean, leaving the salt behind. The more evaporation that takes place, the saltier the ocean becomes. And because the ocean is farther from the surface on the equator, it absorbs more heat and evaporates more water
Sea water is salty give reason?
The oceans are salty because of the atmosphere. Rainwater, snow, and rivers contain dissolved minerals and salts that get trapped in the oceans. The more water evaporates, the more the salt gets deposited. During the evaporation process, the water loses its excess of minerals, which crystallize. Thus, the oceans contain more of these minerals than the rivers.
Why is sea water salty?
The oceans are salty because the seas contain an enormous amount of dissolved salts. The amount of salt in the oceans is approximately 3.5 times the amount of salt in all of the world’s rivers and lakes combined. Water in the atmosphere before it reaches the ocean does not contain much salt. The water that evaporates from the oceans returns to the ocean in the form of precipitation, leaving behind an increasingly salty ocean. Because the amount of water in the oceans is so large
