Lesson 16 Assessment

Why was the accident at Chernobyl an example of transboundary pollution?

• It started in the Soviet Union and spread to other countries.
• It required countries outside of the Soviet Union to interfere.
• It caused boundary disputes between the Soviet Union and Sweden.
• It resulted in new foreign policies in the Soviet Union.

Why was pollution in Europe not a concern before the Industrial Revolution?

• factory machines were made from natural wood
• people mostly used hand tools to make goods
• fuel did not contain that many chemicals
• power plants were built mostly in the country

Which of the following is an example of general pollution?

• a volcano erupting and releasing poisonous gases into the air
• air pollution from the burning of coal to produce electricity
• a car accident that causes gasoline to leak into a river system
• all of the above

What are the two types of pollution caused by human activity called?

• natural pollution and inorganic pollution
• chemical pollution and gaseous pollution
• acid fuel pollution and coal fuel pollution
• general pollution and accidental pollution

How did the accident at Chernobyl in April of 1986 happen?

• nuclear reactor became too hot to control, causing an explosion through the reactor
• power plant was operating during an acid rain storm, producing a very toxic mixture
• fire started in a factory, and the smoke released poisonous gases and fumes into the air
• group of criminals put nuclear chemicals into a river, polluting the entire river system

How did the Soviet government try to prevent radioactive pollution from leaving the affected reactor?

• by burying the reactor 2,500 feet below the ground
• by designing special tools to take apart the reactor
• by building a large concrete box surrounding the reactor
• by putting toxins inside the reactor to stop the radiation

Why is the area where Germany, Poland, and the Czech Republic meet called the "Black Triangle"?

• It receives lots of air pollution from surrounding countries.
• It has blackened air since it is major source of air pollution.
• It is the location of the first factory that used lignite as fuel.
• It is where most of the world's lignite and coal is found.

Why is acid rain harmful?

• It slowly eats away at an object until it is destroyed.
• It prevents water from entering the soil that it covers.
• It puts toxic chemicals into the land and water.
• It mixes with nitrogen oxide and sulfur dioxide.

Why would a factory that burns coal install devices called "smokestack scrubbers"?

• It would produce more fuel at a much lower cost.
• It would use resources other than lignite to make fuel.
• It would make air pollution spread to other countries.
• It would allow the factory to create less air pollution.

What type of pollution was the Tisza-Danube Cyanide Spill?

• acid rain
• general pollution
• accidental pollution
• intentional pollution
