The definition of a solute that is capable of dissolving in a solvent is that the force of attraction between the atoms in a solute are not strong enough to keep the molecule together when surrounded by the many negative and positive partial charges that make up the solvent. I don’t know exactly how many ion-dipole bonds Cl- and Na+ form with H(partial ...

If I am understanding the question correctly those straight lines may not actually be lines, they may be strips or bands and they are bands that are not actually there. The bands are a result of combining the available sea floor profile data into a single map and are bands of sea bottom that follow the course of ships that do such mapping - thus the straight ...

West of the Continental Divide it is the Cordilleran ice sheet. I think the blue line here would have been ice shelves where it is in deep water. It also shows some ice-free land (note, sea level was 125 m lower).

Just a rough estimation of your plan. The oceans contain approximately 1.3E9 cubic km of water --> 1,3E18 tonnes (1000kg) of salt water. In there there 3% of salt --> 3,9E16 tonnes of salt, which would require 1,8E16 m^3 of dry storage. Assuming we make the mountain 3 km high, this would still require 6 million square kilometer of storage, which is ...

Desalination of ocean water costs energy; beside fresh water, you gain salt. With some additional energy invested, you could purify this salt consisting to large extent of sodium chloride (NaCl) which may be used as table salt. In other places, you mine for rock salt from underground mines, and equally perform a purification of salt, yet without the ...

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 the oceans has been stable for millions of years, indicating that there is an equilibrium between processes in both directions. Salt is removed from the oceans ...

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 saltwater of course, probably by 35 g). Which contains about 4.7x1019 kg of salt. To reduce the salinity to just 34 g/kg, you need to extract 1.4x1018 kg of salt ...

The residue dry powder you refer to is salt. Salt is toxic to most plants. The United Nations claims the world is already losing 2000 hectares per day of farm land to salt-induced degradation. This is land that is used to feed people. In some situations, salt from affected lands can contaminate underground sources of drinking water, which will affect people, ...

Think of what happens with the fresh water that we extract via desalination. It's used for drinking, general water supply, farming and some other industries. In either case it will either eventually evaporate and eventually end up in the ocean or it is discharged back into the ocean. Some water is of course lost in the process, but it's a relatively small ...

The Bay of Fundy is shaped like a funnel, which amplifies the tidal magnitude, as the water is "squashed" into the bay. There are several other funnel-shaped bays with a large tidal amplitude around the world, e.g. Bristol Channel in Wales, UK.

Waves travel over the ocean surface with columns of water molecules moving in a circular motion, as seen here. As you can see, when the waves reach shallow ground, the friction of the molecules over the seabed causes it to topple over and break. If in your case there is a tall obstacle under the water instead of the gradual slope, the wave energy will but ...
