The proportion of dissolved substances in seawater is typically expressed in parts per thousand (ppt) or salinity, which is the concentration of dissolved salts in seawater.
The law of constant proportion, also known as the law of definite proportions, states that a chemical compound always contains its component elements in fixed ratio by mass. In seawater, this law applies to the dissolved salts, primarily sodium chloride, which consistently makes up about 3.5% of seawater by mass. Regardless of where seawater is sampled, the proportion of these dissolved salts remains relatively constant, demonstrating that the chemical composition of seawater is uniform despite variations in other components. This consistency is crucial for marine life and oceanic processes.
Approximately 97% of Earth's water is found in the oceans as saltwater, while only about 3% is fresh water. Of the fresh water, the majority is locked up in glaciers and ice caps, with a much smaller proportion found in groundwater, lakes, and rivers.
Seawater is water with salt in it
many places mostly in seawater (erosion) and in the earths crust
Seawater is the water that comes from the sea, and the water is very salty, and is thus called saltwater.

The proportion of dissolved salts in seawater has remained relatively stable over millions of years. It is primarily maintained through a balance of inputs from sources like rivers and outputs through processes like evaporation.
Seawater is hypertonic to drinking water. This means that seawater has a higher concentration of solutes (such as salts) compared to drinking water. Drinking seawater can lead to dehydration as the body would need to excrete more water to get rid of the excess salts.
The water.
yes it is because with droughts there is always seawater and then you can have water
Seawater can be turned into drinkable water through desalination.
