Answers
Answer:1
Explanation: Condensation is the change of water from its gaseous form (water vapor) into liquid water. Condensation generally occurs in the atmosphere when warm air rises, cools and looses its capacity to hold water vapor. As a result, excess water vapor condenses to form cloud droplets.
Answer:2
Explanation: “Inland waters” are aquatic-influenced environments located within land boundaries. This includes those located in coastal areas, even where adjacent to marine environments. Inland water systems can be fresh, saline or a mix of the two (brackishwater)
Answer:3
Explanation: Seawater is toxic to humans because your body is unable to get rid of the salt that comes from seawater. Your body normally gets rid of excess salt by having the kidneys produce urine, but it needs freshwater to dilute the salt in your body for the kidneys to work properly.
Answer:4
Explanation: Evaporation is used to separate salt from sea water. The water evaporates and turns into water vapors and the salt is left behind. The water vapors can then be cooled by the process of Condensation to turn them back into water.
Answer:5
Explanation: Waterborne illness is caused by recreational or drinking water contaminated by disease-causing microbes or pathogens. Examples are typhoid fever, cholera and Hepatitis A or E. Other microorganisms induce less dangerous diseases. Often, diarrhea is the main symptom.
