Which of the following is a major source of water pollution?
-
Industrial waste
-
Agricultural runoff
-
Sewage discharge
-
Acid rain
B
Correct answer
Explanation
Agricultural runoff, containing fertilizers, pesticides, and animal waste, is a significant source of water pollution, contributing to eutrophication and harming aquatic ecosystems.
Which human activity is a major contributor to the acidification of the oceans?
-
Renewable Energy Production
-
Sustainable Agriculture
-
Electric Vehicle Usage
-
Fossil Fuel Burning
D
Correct answer
Explanation
Fossil fuel burning, particularly the burning of coal and oil, releases large amounts of carbon dioxide into the atmosphere. Carbon dioxide dissolves in seawater, forming carbonic acid, which leads to the acidification of the oceans.
Which human activity is a major contributor to the pollution of the oceans?
-
Renewable Energy Production
-
Sustainable Agriculture
-
Electric Vehicle Usage
-
Industrial Waste Discharge
D
Correct answer
Explanation
Industrial waste discharge, particularly the discharge of untreated or poorly treated wastewater, is a major contributor to the pollution of the oceans. Industrial waste can contain harmful chemicals, heavy metals, and other pollutants that can contaminate marine ecosystems.
What is the primary source of water pollution?
-
Industrial waste
-
Agricultural runoff
-
Sewage discharge
-
All of the above
D
Correct answer
Explanation
Water pollution can be caused by a variety of sources, including industrial waste, agricultural runoff, and sewage discharge.
What are the major types of water pollutants?
-
Organic pollutants
-
Inorganic pollutants
-
