I don’t have the map from your textbook in front of me — could you upload or describe it (or tell me the chapter/page)? I can give more exact answers once I can see the map.
Meanwhile, here are likely answers and how to get them from the map:
1) Using a Key: Which island’s coal deposits are distributed over a wider area?
- Likely answer: South Island.
- Why: Most mapped coal fields in New Zealand are spread along the West Coast, Southland and Otago in the South Island, so the South Island shows a wider spread. Check the map key and count/compare the number and area of deposit symbols on each island to confirm.
2) Finding locations: What city is farthest from a coal deposit?
- Likely answer (map-dependent): Auckland is often the farthest major city from major coal fields, because most coal is in the South Island and in lower North Island/Waikato regions.
- How to determine on the map: measure or visually compare straight‑line distance from each labeled city to the nearest coal symbol; the city with the largest gap is the correct answer.
3) Finding locations: Are most of the coal mines in New Zealand near cities or some distance away?
- Answer: Most are some distance away from major cities — they are generally in rural or regional areas (mining towns or districts rather than big urban centres).
- Reason: Coal fields are commonly in mountainous, coastal or agricultural regions rather than inside large cities.
4) Making a hypothesis: Based on what you have learned in this chapter, what types of mining do you suppose New Zealanders use to get their coal? Explain your answer.
- Answer: They use both open‑cut (opencast) mining and underground mining (methods such as room‑and‑pillar and longwall).
- Explanation: Lignite and other soft coals that lie near the surface (for example in Southland/Otago) are economical to extract by open‑cut methods. Harder, deeper bituminous coals (for example parts of the West Coast) are often recovered by underground mining techniques like longwall or room‑and‑pillar. The choice depends on coal depth, seam thickness, geology and environmental/land‑use considerations.
If you upload the specific map or give the list of cities shown on it, I’ll give precise answers tied to that map.
