Which of these is an environmental consequence of the shrinking of the aral sea? a. the salt content of the water has increased b. more nesting birds have come to its beaches c. fish populations have increased to unhealthy levels d. the water have become less polluted

ANSWER:

The environmental consequence of the 'shrinking of the Aral Sea' is the 'salt content of the water has increased'.

EXPLANATION:

The mineral and salt content of the Aral Sea rapidly increased. Because of this, the water became unfit to drink. Also, this became main cause of large population of different species of fish unable to survive in the sea. Due to this, the fishing industry was eventually destroyed. Due to declining sea level the population of shoreline areas begun to decrease. Because of decrease in sea level, the climate became difficult for settlement. Summer was extremely hot and winter became extremely cold.

The answer is c epicenter

So  if  the sum of the enthalpies of the reactants is greater than the products, the  reaction  will be  exothermic.  if  the products side has a larger enthalpy, the  reaction  is  endothermic. you may wonder why  endothermic reactions, which soak up energy or enthalpy from the environment, even happen
