Why is seawater salty and lake water not?

Lake water is salty because it has all the minerals that your body needs to function. When water evaporates from lakes the minerals are left behind. The water from rivers and oceans cannot contain enough minerals to sustain the life of humans or other organisms.

Why is salt water salty and lake water not?

The high salt content of seawater about 3.5 percent by weight, is the natural way oceans maintain their balance of freshwater and salt. Water absorbs the minerals around it in the oceans, so that when the water evaporates, the minerals are left behind. Over time, the salt content of a body of water will increase, because the water absorbs more minerals from the surrounding environment as it evaporates.

Why is the water in the ocean salty and lake water not?

The oceans are salty because of the saltiness of the water that they hold. The water in the oceans contain about 70 grams of dissolved salts per kilogram of water. This is much more than the water in rivers, lakes, or underground water. The salinity of the water in the world's oceans is about 5%. The salt that is dissolved in the water is so fine that it will not cause any damage to living things.

Why is seawater salty and lake water not salty?

The seas are salty in part because they contain dissolved minerals. These minerals crystallize as deposits on the ocean bed, and the salty seawater that flows over the deposits is left behind. Lakes, on the other hand, are not replenished with fresh water, so the water they contain is just what was there when the lake formed. Over time, groundwater seeps into the lake and its water becomes slightly salty as the minerals in it crystallize. Because the lake water never mixes with the salty ocean

Why is sea water salty and lake water not?

The oceans contain about five times as much salt as freshwater. If you collected all the water in the oceans and all the water in lakes together you would have about 300,000 Earth’s worth of water. Of that 300,000, only about one percent would be freshwater. The other 99.9% would be salty. So, if you collected the water from lakes and seas and mixed it together, it would have the consistency of a block of concrete.
