How is salinity affected when precipitation increases

Answers

Answer:

Evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However these "salinity raising" factors are continually counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice.

Which one of these situations is commonly caused by acid rain?a. people being poisoned by drinking water

b. fish and birds in freshwater habitats dying off

c. people receiving acid burns on there skin

d. whales and dolphins dying off in the oceans

Answers

A situation that is commonly caused by acid rain is the dying off of fish and birds in freshwater habitats. Thus, the correct option for this question is B.

What do you mean by Acid rain?

Acid rain may be defined as a type of precipitation that correspondingly include acidic components, like sulfuric acid, nitric acid, etc. that fall to the ground from the atmosphere in wet or dry forms like rain, fog, hail, etc.

The pH of acid rain is generally low compared to normal water. So, it causes numerous impacts on the earth's surface. But the most consequential influence of acid rain is the destruction of fish and birds in freshwater habitats.

It generally lowers the pH of the freshwater ecosystem and makes it unfavorable for many organisms like producers, small fishes, birds, etc. They cannot adapt themselves to such lower pH and have to dye off.

Therefore, the correct option for this question is B.

How does the water molecule differ from other compounds of similar size?

Answers

Water molecules does behave differently from other chemical compounds. because:

  • Water molecules contains a oxygen atom (O) and the two hydrogen atoms (H) which are asymmetrically arranged.

  • Water molecule can form up to four of hydrogen bonds and together, they give water a cohesiveness pertains in liquids.

  • In some substances, the atoms and molecules move closer together as they get colder and then solidify or freeze up. Water does attains its greatest density at four degrees Celsius because the water molecules are packed closest together at a particular temperature

  • Water does play a role in climate not only in its liquid and solid states.

  • water vapour in the atmosphere affects the heat budget of the Earth and greenhouse effect.

Conclusively, water is a universal solvent that is taken in by man. Its molecules are not harmful to man when consumed.
