Describe the differences in treatment of ground water and salty water
Answers
Answer:
The groundwater found in lakes, rivers, and streams all throughout the world is very different from the salt water found in the oceans and seas of the earth. Few plant and animal species can survive in both types of water; most are only adapted to one.
Explanation:
Salinity:
The name itself is arguably where the biggest difference lies. Salt, or sodium chloride, is present in seawater. Small levels of salt may be present in groundwater, but not enough for it to be referred to as saltwater. The average salinity of ocean water is 3.5 percent. This indicates that every liter of saltwater contains 35 grams of dissolved salt.
Density:
Because sodium chloride is dissolved in salt water, it has a higher density than in groundwater. This indicates that salt water is heavier than fresh water of the same volume. Due to the fact that warmer salt water is less dense than colder salt water, the colder water sinks to the ocean floor. Water is denser at lower temperatures, but as it freezes into ice, it loses density and floats on the surface.
Freezing Point:
Ocean water has higher freezing and boiling points than freshwater, but only the higher freezing point is of interest to nature. Although it can go even lower if the water is under pressure or has larger salt content, the average freezing point of ocean water is -2 degrees Celsius. Freshwater typically freezes at zero degrees Celsius.
Tonicity:
Water will flow to the side of a semipermeable membrane with the greater solute concentration in an effort to balance the solute concentration when water with different salt concentrations, or any solute, is positioned across the membrane. When talking about water, tonicity is crucial for the types of plants and animals that inhabit the body of water. Animal and plant tissues are hypertonic to saltwater. In other words, these organisms lose water to their surroundings. They, therefore, need to consume water continuously and excrete salt. Groundwater, on the other hand, is hypotonic to both animals and plants.
These creatures rarely need to consume water, but they must frequently excrete it because water is rapidly absorbed in an effort to balance the concentration of salt. Osmoregulation is the name for this adaptation.
