Although the question is very badly written and hence not easy to work out the meaning of, I assume the peculiarity referred to is that seawater and hard waters are similar. If so, there is no peculiarity at all; it is what we expect. Both contain higher than normal levels of dissolved salts, so there salinity is roughly the same. In the case of seawater, it is sodium chloride for the most part, but for hard water it is normally calcium salts.

1. Only the temporary hardness of water (caused by bicarbonates) is decreased by boiling: bicarbonates were transformed in insoluble carbonates and these compounds become a precipitate. 2. The permanent hardness is not influenced by temperature.
Hardness: The measure of how resistant a material is to deformation or scratching. Density: The amount of mass in a given volume of a material. Conductivity: The ability of a material to transfer heat or electricity. Strength: The ability of a material to withstand applied forces without yielding or fracturing. Ductility: The ability of a material to be stretched or deformed without breaking.
Thermohaline circulation is a global oceanic circulation driven by differences in temperature and salinity. Cold, dense water sinks in polar regions and flows toward the equator, while warmer, less dense water flows back towards the poles near the ocean surface. This process helps regulate Earth's climate by transporting heat and nutrients around the world.

Oceans are big water bodies. Salinity is due to the presence of minerals in water.
Surface salinity in polar regions varies seasonally due to the formation and melting of sea ice.
The salinity of water in polar regions varies seasonally because of the melting of sea ice during warmer months.
During warmer months the salinity level goes down because of ice melting. Ice is mostly fresh water.
Coastal waters have a lower salinity due to the vast amount of freshwater runoff pouring into the sea from rivers and streams. PM
Three factors are evaporation and freezing of sea water.
The hardness of sand is higher.
The mineral that scratches gypsum has a hardness greater than 2 on the Mohs scale. Gypsum has a hardness of 2 on the Mohs scale, so any mineral that can scratch it must have a hardness greater than 2.
