Flashcard 1: Which pollutant is primarily associated with industrial smog?
Answer: Sulfur dioxide. Creates gray, hazy air pollution in industrial areas.
Flashcard 2: Which human activity is a major source of nitrogen oxides?
Answer: Vehicle emissions and industrial processes. High-temperature combustion creates these reactive compounds.
Flashcard 3: What is the primary source of volatile organic compounds (VOCs)?
Answer: Industrial processes and vehicle emissions. Evaporate easily and contribute to ground-level ozone formation.
Flashcard 4: What is the main source of noise pollution in urban areas?
Answer: Traffic and industrial activities. High decibel levels from engines and machinery in cities.
Flashcard 5: Identify a source of carbon monoxide pollution.
Answer: Incomplete combustion in vehicles. Occurs when insufficient oxygen prevents complete fuel burning.
Flashcard 6: Identify a major source of soil pollution.
Answer: Improper disposal of industrial waste. Leaches heavy metals and chemicals into soil layers.
Flashcard 7: Which gases are greenhouse gases?
Answer: Carbon dioxide, methane, nitrous oxide. Trap heat in Earth's atmosphere, causing global warming.
Flashcard 8: What is the main source of water pollution?
Answer: Industrial discharge and agricultural runoff. Introduces chemicals, nutrients, and toxins into water systems.
Flashcard 9: What is mercury pollution primarily linked to?
Answer: Coal-burning power plants. Mercury in coal is released when burned for electricity.
Flashcard 10: What is a significant source of urban air pollution?
Answer: Transportation and industrial emissions. Concentrated human activities create multiple pollution sources.
Flashcard 11: What is the main source of sulfur emissions?
Answer: Burning of coal and oil. Sulfur content in fossil fuels creates acidic emissions.
Flashcard 12: Which pollutant is most commonly associated with acid mine drainage?
Answer: Sulfuric acid from exposed sulfide minerals. Forms when pyrite minerals oxidize upon exposure to air.
Flashcard 13: What is the main source of indoor air pollution?
Answer: Cooking and heating with solid fuels. Biomass burning releases particulates and toxic compounds indoors.
Flashcard 14: Identify a common source of plastic pollution.
Answer: Improper disposal of plastic products. Single-use plastics and inadequate waste management systems.
Flashcard 15: Identify a primary source of groundwater contamination.
Answer: Leaking underground storage tanks. Fuel storage corrosion allows chemicals to seep underground.
Flashcard 16: What is a primary source of marine pollution?
Answer: Oil spills and plastic waste. Persistent pollutants that harm marine ecosystems globally.
Flashcard 17: Identify a major effect of acid rain.
Answer: Damage to aquatic ecosystems and forests. Acidic water kills fish and trees, damages buildings.
Flashcard 18: Which pollutants are primarily emitted from vehicles?
Answer: Carbon monoxide, nitrogen oxides, hydrocarbons. Produced by internal combustion engines in cars and trucks.
Flashcard 19: Which human activity is a significant source of thermal pollution?
Answer: Nuclear power plant operations. Cooling water discharge raises nearby water temperatures.
Flashcard 20: What is the main human source of carbon dioxide?
Answer: Burning of fossil fuels. Coal, oil, and gas combustion for energy production.
Flashcard 21: What is acid rain primarily caused by?
Answer: Sulfur dioxide and nitrogen oxides in the atmosphere. These gases form acids when dissolved in precipitation.
Flashcard 22: What is the primary source of agricultural pollutants?
Answer: Pesticides and fertilizers. Applied to crops but often wash into water systems.
Flashcard 23: Which pollutant is primarily associated with coal combustion?
Answer: Sulfur dioxide. Coal contains sulfur compounds that form this gas.
Flashcard 24: What is thermal pollution?
Answer: Excess heat released into water bodies. Raises water temperature, reducing dissolved oxygen levels.
Flashcard 25: What is the main source of noise pollution in urban areas?
Answer: Traffic and industrial activities. High decibel levels from engines and machinery in cities.
Flashcard 26: Which pollutant is primarily responsible for ozone layer depletion?
Answer: Chlorofluorocarbons (CFCs). Used in refrigeration and aerosols before being banned.
Flashcard 27: What is eutrophication?
Answer: Excessive nutrients in water bodies causing algal blooms. Leads to oxygen depletion and fish kills in water bodies.
Flashcard 28: Which pollutant is most associated with respiratory issues?
Answer: Particulate matter. Tiny particles penetrate deep into lungs and bloodstream.
Flashcard 29: Which pollutant is most commonly associated with smog?
Answer: Ozone and particulate matter. Forms when sunlight reacts with nitrogen oxides and VOCs.
Flashcard 30: What human activity contributes to eutrophication?
Answer: Overuse of fertilizers in agriculture. Nitrogen and phosphorus runoff stimulates excessive plant growth.
