Why is ocean water salty give reason?
A few thousand years ago, the oceans were extremely salty. Nowadays, the oceans are less salty than they were before the start of the Industrial Revolution, because of the increased absorption of freshwater from rivers and lakes. Since the ocean is a large body of water, even a small change in its salt content can have a huge effect on its volume. Over the past thousand years, the average salt content has decreased by about one percent. This means that the sea level has also decreased by that amount.
Why is water salty give reason?
When the atmosphere condenses and water vapor forms raindrops the water in the atmosphere is collected in rivers, lakes, the ocean, and seas. The water that makes up rivers and lakes is usually too salty to drink. The water in the oceans and seas is much less salty than the water in rivers and lakes.
Why does water taste salty give reason?
Most people believe that salty water tastes because of the mineral salts it contains. According to the U.S. National Oceanic and Atmospheric Administration, the average amount of dissolved minerals in ocean water is about 5 grams per liter. Of those minerals, about 85% is sodium chloride, a type of salt that our bodies need for normal cell function and homeostasis. The rest is made up of potassium, calcium, magnesium, and other minerals.
Why is ocean water salty and give reason?
The chemical make up of water is the same everywhere on the earth, but the amount of minerals dissolved in the water depends on the chemical makeup of the soil of the area and the amount of rainfall. The ocean is salty because rivers flowing into the ocean carry minerals along with them. Over time, the ocean becomes more and more salty as the minerals leach out.
Why is water salty on Mars give reason?
Not all the water on the surface of Mars is salty. The salty water is only found in a few locations, such as the northern hemisphere’s ice caps and in the northern hemisphere’s ocean. The salty water is created when salty groundwater seeps into the salty ice. This salty water is said to be a briny mix of water and sodium chloride. The high salt content of this salty water is one of the main motives behind why humans will need to drink this water when they
