Teacher's Note: Use the key term in your answer.
2. Why is Nepal prone to earthquakes? 3. How do earthquakes occur? 4. What increased the risk? Think: why do diseases spread?
Show answer
Answer: Nepal lies where the Indian plate pushes under the Eurasian plate, so stress builds up and is released as earthquakes. Earthquakes occur when rocks suddenly slip along a fault. Poorly built houses, crowded towns and building on unsafe ground added to the risk. Diseases spread because of dirty water, no toilets, crowding in camps and broken health services.
Teacher's Note: Give an example if the question allows.
Case Study 3: Oil Spills in the United States

Teacher's Note: Learn this point and write it in your own words.
1. How does oil waste disintegrate? 2. What happens at the coast? 3. Hazards of oil spills.
Show answer
Answer: Oil breaks down slowly by evaporation, sunlight, bacteria and waves. At the coast it mixes with sand and mud, kills plants and animals, and is hard to remove. The hazards are poisoned fish and birds, damaged coastal homes of wildlife, polluted water and loss of jobs in fishing and tourism.
Teacher's Note: Use the key term in your answer.
4. How can spills be prevented? 5. Clean-up methods. Think: how is tourism affected, and can spills be prevented?
Show answer
Answer: Prevent spills with strong double-hulled ships, regular pipeline checks, strict rules and training. Clean up with floating barriers (booms), skimmers, absorbent materials, special chemicals and bacteria. Spills hurt tourism because beaches are dirty and unsafe. Many spills can be prevented by care, though accidents cannot be completely removed.
