Why is the ocean water salty?

Why the ocean water isc salty?

The reason why ocean water is salty is because they contain very large amounts of salt. On average, the oceans on Earth contain about 3.5% salt (sodium chloride), which is the equivalent of a total of about 50 million billion tons of salt. If you spray all of this salt on the land, they are enough to create a layer about 152 meters thick.

How did this huge amount of salt reach the oceans? According to the study, part of the salt is derived from rocks and seabed sediments. Other salts escape from volcanic vents hidden deep in the waves. However, most of the salt in the oceans comes from the land that surrounds us.

Rainwater dissolves minerals and salts from rocks and dry soil, then swept them away into the river. However, the salt accumulation in rivers is still very small, less than 1/200 of the amount of sodium chloride exists in seawater. So much of this salt still accumulates there and eventually reaches the oceans as river water flows through the estuaries.

Importantly, the salt is then more concentrated in the oceans, due to the sun's heat causing the surface water to evaporate, leaving the salt behind. Globally, 4 billion tons of salt from rivers enter the ocean each year. Therefore, our oceans are bound to become much more salty and salty than in the beginning. However, the amount of salt added each year from the rivers is now generally in balance with the salt accumulating back to the bottom of the sea.

The salinity of the sea water is not the same across the Earth. In the polar regions, seawater is not as salty as elsewhere because it has been thawed and dissolved. Meanwhile, in tropical areas around the equator, the increase in the amount of hot heat causes water to evaporate more than rainwater to fall, making the sea saltier.

There is growing evidence that salinity differences across the globe are increasing. For example, as sea temperatures rise, a portion of the Atlantic accelerates evaporation and thus increases the salinity of the seawater. This may seem insignificant, but the more salt in the oceans, the more salty the seawater will be and the slower it will flow, affecting the flow of essential nutrients in the ocean. .

Big Data

Data collection and interpretation are very important to the seed breeding program. Without data and its interpretation, progress is impossible. Technology will create the ability to collect new data, and the effective innovation of a successful company will result. In addition, as technology evolves, the cost of technology decreases. For example, the cost per gigabyte of storage in 1980 was $ 500,000. Today the price is less than $ 0.03. This is a huge expense for the amount of data collected. In pig breeds, there is a wave of data collection. Basic data collection includes weight, number of births, birth year, age group, wean to service time, door count, and more. These features do not require sophisticated technology. Ultrasonic balance, depth, and intramuscular oil are being collected because of advances in ultrasound technology. Improvements in body and food quality have emerged over the years, including tools to improve pH, maripling, color, and digestion. All of these factors ar...

Why Apple Logo Is Half Bitten?

Why Apple Logo Is Half Bitten? Today we want to take you closer to the development of one of the world's most famous logos: the Apple logo. Steve Jobs, who grew up as a social orphan in Mountain View, California, was a big fan of the electronics industry while still at school. After he dropped out of college in Portland, he worked for several years at the computer company Atari. In 1976, Jobs finally founded Apple Computer Coporation with Steve Wozniak and Ronald Wayne. Since Jobs was temporarily a Frutarian in the 1970s, i.e. based on fruit, the apple in the company name was also derived from its own statements. But there are other theories for the fruity company name: Steve Jobs is said to have been on vacation shortly before the name was given, and to have been inspired by an apple harvest at the resort. Or else, the idea for the name came from one of his favorite bands, the Beatles, which was under contract with Apple Records. There is also a rumor that Jobs and...
