Are there any saltwater rivers on Earth?

The water in any river draining the sea is infinitely recycle-able (from rain replenishment), whereas the salt from any terrestrial source is not. So salty rivers, if any, won't exist permanently. ...

While desalinating ocean water, would it be bad if we didn't pump the brine back into the ocean?

What does it take to reduce the salinity? The salinity of sea water is around 35 g/kg. There are around 1,350,000,000 km³ of water, so roughly 1.3x1021 kg of seawater (1 kg/l, which is a bit off for ...

Why is the sea salinity high in the Mediterannean and Red Sea and low in Indonesia and Malaysia?

It has nothing (or very, very little) to do with desalinization plants. It has to do with the balance between Evaporation minus Precipitation (E-P), rivers, and advection. The link to E-P is the main ...

Thermohaline Circulation in the Oceans

Salinity and temperature both affects the density of sea water. When water with a fixed salinity cools down, it becomes heavier and sinks. In the same way, when vapor or ice removes water from sea ...

While desalinating ocean water, would it be bad if we didn't pump the brine back into the ocean?

The oceans are salty because the slightly acidic rainwater dissolves minerals from ores and rocks and runs into the sea. This is a continual process, a consequence of erosion. However, the salinity of ...

Thermohaline: Why is cold and dense seawater salty when warm water holds more dissolved salts?

Warm water does hold more salt - at saturation, but seawater isn't even close to saturation. Surface sea water gets warm, starts to evaporate (hence clouds) and therefore gets denser. So it sinks to ...
