In what ways is the water in seas and oceans is useful even though it is salty?
Answer: In general Ocean,water is used for recreation as in swimming as well as boating. Saltwater evaporates into water vapour and it will become clouds then becomes rain as well as snow then lands on the ground watering the earth. Of course it can be used for drinking purpose by filtering as well as cleaning.
How sea water is useful for us?
Sea water is very useful to us as it has the biological and chemical applications. ☆ From the sea water, a water can be taken to generate the electricity (hydro electricity). ☆ Sea water is the major source of many minerals which are very important in our day to day life.
Why sea water is Sakty?
Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks. Ocean water seeps into cracks in the seafloor and is heated by magma from the Earth’s core.
What if sea water is not salty?
A sea without salt would decimate marine life and dramatically affect our weather and temperatures, making human life on Earth very difficult, if not impossible. There are roughly 228,450 species in the ocean, and as many as 2 million more to be discovered. But for the most part, all saltwater species would perish.
How is the water in the seas and oceans?
The water in the oceans is saline (saltwater), but, what do we mean by “saline water?” Saline water contains significant amounts (referred to as “concentrations”) of dissolved salts. In this case, the concentration is the amount (by weight) of salt in water, as expressed in “parts per million” (ppm).
Why sea water is useful even though it is not potable?
Although seawater is not potable, it has various other kinds of uses which prove its importance: Water from oceans can be used for making hydroelectricity, a form of renewable source of energy. It can be used as a cheap transport method. They can be used for activities like scuba diving, water sports, etc.
How is sea water different from river water?
Seawater has a more uniform composition than river water. It contains, by weight, about 3.5 percent dissolved salts, whereas river water has only 0.012 percent. The average density of the world’s oceans is roughly 2.75 percent greater than that of typical river water.
Is sea water homogeneous or heterogeneous?
Because of the presence of mixture of several dissolved gases in sea water it is classified as homogeneous mixture. and due to the presence of salt and suspended impurities sea water is also classified as heterogeneous mixture.
What would happen without salt?
The human body can’t live without some sodium. It’s needed to transmit nerve impulses, contract and relax muscle fibers (including those in the heart and blood vessels), and maintain a proper fluid balance. It doesn’t take much to do this.
What if the sea was fresh water?
All of the organisms in the sea are adapted to saltwater. If they were suddenly immersed in freshwater, too much water would diffuse into their bodies and they would die. Not only have those organisms been destroyed, but massive amounts of carbon dioxide and methane have been released into the atmosphere.
What makes a sea a sea?
In general, a sea is defined as a portion of the ocean that is partly surrounded by land. Given that definition, there are about 50 seas around the world. But that number includes water bodies not always thought of as seas, such as the Gulf of Mexico and the Hudson Bay.
Why the water is life?
Substances easily dissolve or mix with liquid water, which is why water sustains life. Water moves sugars and nutrients inside plants. In animals, the water in blood transports energy and oxygen around the body and helps remove waste.
Why can’t sea water be used as drinking water?
The main reason behind this is the high salt content of sea water . This makes sea water highly abrasive and corrosive . Due to this it cannot be transported either in containers or via pumps . However many attempts are being made across the world to convert sea water into drinkable water .
Why can’t we transport salt water by boat?
The main reason behind this is the high salt content of sea water . This makes sea water highly abrasive and corrosive . Due to this it cannot be transported either in containers or via pumps .
How much salt is in sea water?
In a word… “salt”. Sea water is, on average, about 3.5\% salt by weight. Mostly sodium chloride (NaCi… table salt… along with traces of other salts). In other words, every liter of water contains about 35 grams of NaCl. The weight of about 12 one-cent coins today. This does not make it poisinous.
Why can’t human beings use water for drinking?
Human can’t use it for drinking because our kidney which is responsible for making excrete unable to get rid of it, if it is in bulk mass. plants cannot use it because if we irrigate there will be high mineralization of soil..and plant can’t use it all.
