Lesson 16 Assessment 24+25

Which of these was the main pollutant released by the Chernobyl power plant explosion?

• cyanide

• nitrogen oxide

• nuclear radiation

• sulfur dioxide

The Chernobyl power plant explosion and the Tisza-Danube cyanide spill are both examples of

• water pollution

• accidental pollution

• radiation pollution

• general pollution

The map below best illustrates which problem?

• water pollution

• transboundary pollution

• toxic-chemical pollution

• general pollution

Which of these is a major cause of acid rain?

• spraying pesticides on crops

• burning fossil fuels for energy

• dumping sewage in river systems

• using uranium to generate electricity

This image shows the effects of pollution in Europe’s “Black Triangle.” What is the primary cause of this damage?

• nuclear radiation from the region’s power plants

• cyanide leaks from the region’s factories and power plants

• acid rain caused by air pollution from factories and power plants

• accidental pollution from the Chernobyl power plant explosion

Acid rain forms when

• sulfur dioxide and nitrogen oxides mix with water in the air.

• nuclear radiation contaminates soil and crops.

• cyanide mixes with water in rivers.

• uranium is improperly stored.

How did the accidental spill of cyanide at a mine in Romania spread to neighboring countries?

• Winds blew cyanide to other countries.

• Rivers carried cyanide to other countries.

• Crops poisoned with cyanide were sold in other countries.

• Storms dropped rain poisoned with cyanide on other countries.

What was the major cause of the power plant explosion at Chernobyl?

• brain drain

• human error

• extreme weather

• centrifugal force

Which of the following is a negative effect of the Chernobyl power plant explosion?

• higher rates of cancer in Belarus

• contamination of soil and water in Belarus

• contamination of fish and reindeer populations in Lapland

• all of the above

Which of the following is true of nuclear radiation?

• Nuclear radiation is energy with no smell or taste.

• Nuclear radiation is deadly in large amounts.

• Nuclear radiation comes from nuclear reactions.

• all of the above
