Because plants and animals in seawater cannot adapt to freshwater and vice versa.
Sodium and chloride ions make up most of seawater volume. They form the table salt, sodium chloride.
Sources that add minerals to the ocean: 1. Rock erosion due to carbonic acid in the rain; rivers carry this weathered sediment to the oceans. 2. Hydrothermal vents on the ocean floor. 2 Processes that remove minerals: 1. Evaporation 2. Phytoplankton extract calcium and silicon from seawater.
Salinity lowers the freezing point of water; salt increases the density of seawater.
By using echolocation
False
atm: 10.9204; psi: 160.485
Explanation:
Plants and animals are expertly adapted to their environments. Therefore, if seawater plants and animals are put in freshwater, they will not be able to survive.
Sodium and chloride make up 90% of the salinity content in the oceans.
Weathering of rocks near the oceans due to acid rain (carbonic acid) releases minerals in the rocks into the oceans. Weathered sediments upstream can be carried by rivers to the ocean. Evaporation is the principal natural cause of mineral removal from oceans. Phytoplankton such as diatoms extract minerals from oceans to form their shells.
The presence of large amount of salts increases the density of seawater. During phase changes from solid to liquid, equal amount of water molecules enter and leave the solid state, the addition of salt in water, physically hinders water molecules from entering the solid state. Therefore, seawater remains liquid due to lowering of the freezing point.
Sperm whales are the loudest of all animals on the planet. They use echolocation or a series of clicks to locate giant squid.
Sea ice is less salty because as water freezes, the salt crystals (brine) are released back into the seawater.
Use the equation P(total) = P(atmosphere) + ( r * g * h ) where,
r=rho= Density of the sea water;
g= The acceleration on of gravity = the gravity of earth;
h= The height of the fluid above the object or just the depth of the sea.
