Question

4 multiple choice 2 points which environmental problem affects large areas in both the amazon basin and central africa? deforestation nuclear waste acid rain air pollution 5 multiple choice 2 points \asian tiger habitat diminished by 50%\ \oil spill threatens ecology of the north sea\ \overcropping limits agricultural production in sudan\ these three newspaper headlines are most directly concerned with the lack of pollution controls around the world effect of humans on the environment role of science in limiting environmental problems need for fewer government regulations 6 multiple choice 2 points the two natural features that form a large part of the boundary of chile are lake titicaca and the amazon river basin the pacific ocean and the andes mountains patagonia and the atacama desert the pampas and the strait of magellan

Explanation:

• Question 4: The Amazon Basin and Central Africa are both regions with extensive forests. Deforestation is a major environmental problem in these areas due to activities like logging, agriculture expansion, and urbanization. Nuclear waste is not a widespread issue in these regions. Acid rain is more associated with industrialized areas with high emissions of sulfur and nitrogen oxides. Air pollution, while a concern in some urban areas, is not as large - scale and characteristic as deforestation in these forest - rich regions.
• Question 5: The headlines about the Asian tiger habitat loss (due to human activities like deforestation for development), the oil spill (a human - caused environmental disaster), and overcropping (a human agricultural practice) all show the impact of human actions on the environment. The lack of pollution controls is too narrow as it doesn't cover all the issues (e.g., overcropping is not about pollution controls). The role of science in limiting environmental problems is not directly addressed by these headlines. The need for fewer government regulations is the opposite of what these environmental problems (which often require regulation) might imply.
• Question 6: Chile is a long, narrow country. The Pacific Ocean forms its western boundary, and the Andes Mountains form its eastern boundary. Lake Titicaca is in the Andes but not a boundary of Chile. Patagonia is a region in southern Chile and Argentina, but not a boundary - forming feature in the way the Pacific Ocean and Andes are. The Pampas are in Argentina, not a boundary of Chile.

Answer:

• Question 4: deforestation
• Question 5: effect of humans on the environment
• Question 6: the Pacific Ocean and the Andes Mountains
