Check the meaning of Salinity- I think you have the wrong word.
Salinity means how much salt. Senility- is were you get old and your brain functions do not work as they should. It can happen as early as 50 or as late as 80 most common in the late 70's.
Salinity is the measure of salt concentration in water
Salinity is the amount of salt in something. So, "dry land salinity" is the amount of salt in the dry land involved.
the saltiness of the sea
Salinity refers to the concentration of salt in a body of water. It is typically measured in parts per thousand (ppt) or practical salinity units (PSU). Salinity can affect the density and properties of water, which can impact marine life and ecosystems.
Salinity is the amount of salt in water, expressed as parts per 1,000.
By studying the salinity levels of the ocean, scientists can estimate the age of the Earth because the salinity has increased over time due to the accumulation of minerals and salts washed into the ocean from the Earth's crust. This gradual process of mineral and salt deposition can be used as an indicator of the Earth's age.
It mostly occurs in Australia due to salty rivers or salty water
Not all salts have sodium in them. So a salinity hazard could mean different salts.
Variations in salinity occur due to factors such as evaporation, precipitation, ice formation, and freshwater input from rivers or melting glaciers. These processes can alter the balance of salts in the water, leading to changes in salinity levels.
Salinity is at its worst in the far west of New South Wales, particularly along some reaches of the Darling River. There are also increasing problems with rising salinity levels around Dubbo and Wagga Wagga. See the related link for a map.
Menstruation occur at the age of 9 to 16 years old
Scrotum cancer is extremely rare. Do you mean testicular cancer? If so, then the age is typically 25-34. VERY rare before age 15, and also in old age.
