Tom Burns Homework Assignment

Increased ocean temperature means increased evaporation and therefore increasedprecipitation

Explain what is meant by thermal pollution and discuss the implication for life if a body of water is

affected by thermal pollution

Thermal pollution is the large discharge of hot water into a river or lake that causes asignificant increase in the waters temperature (2-5 degrees)

Many aquatic organisms rely on constant water temperature to aid proper metabolism,survival and reproduction

Solubility of gases decreases as temperature increases causing stress fpr aquatic organisms False temperature cues for organisms Fish eggs do not develop properly Often occurs when water is warmed after use for cooling
