Approximately 71% of the water in the ocean
The amount of water in the ocean temporary decrease.
When it rains, this helps wash minerals into the ocean from the land, which will add more minerals into an area of ocean water. Also, the formation of sea ice can also increase the amount of minerals.
it has the same amount as the ocean
Ocean water is a substance, not a physical or chemical change.
The amount of salt.
Salinity
the reason salt water freezes is because of the amount of salt in the water
The total amount of dissolved salts in ocean water is referred to as "Salinity". :)
The water level in the ocean remains relatively constant due to a balance between the amount of water entering the ocean from sources like rivers and precipitation, and the amount leaving through processes like evaporation and ice melting. Any rise or decrease in sea level is typically a result of long-term climate change or geological factors.
salinity
We can see through the water in some parts of the ocean, but where we can't, it is because of the great amount of sediment stirred up and suspended in the water.
