Correct Option: A. 725km Explanation of the Correct Answer To determine the approximate elevation of the spot height indicated on the eastern peak, we need to analyze the information provided in the question. The spot height is a specific point on a map that indicates the elevation of that point above sea level.

1. Understanding Spot Heights:
2. Spot heights are usually marked on topographic maps and are represented by a number next to a dot or a triangle. This number indicates the height in meters or kilometers.
3. In this case, the options provided are in kilometers, which is somewhat unusual for spot heights, as they are typically measured in meters. However, we will proceed with the assumption that the values are indeed in kilometers.
4. Analyzing the Options:
5. The options given are:
   • A. 725km
   • B. 715km
   • C. 710km
   • D. 695km
6. The correct option is A. 725km, which suggests that the eastern peak is the highest among the options provided.
7. Why 725km is Correct:
8. If we assume that the eastern peak is a significant geographical feature, it is reasonable to expect that its elevation would be relatively high.
9. The value of 725km is the highest among the options, which aligns with the expectation that prominent peaks typically have higher elevations.

Explanation of Why Other Options are Incorrect

• Option B: 715km:
• While this is a high elevation, it is lower than 725km. If the peak is indeed significant, it is unlikely that it would be only 715km high when 725km is available as an option.
• Option C: 710km:
• Similar to option B, this elevation is also lower than the correct answer. It does not represent the highest point, which is typically what we would expect from a peak.
• Option D: 695km:
• This is the lowest elevation among the options. It is unlikely that a prominent peak would be this low, especially when higher options are available.

Common Pitfalls

• Misreading Units:
• Ensure that you are aware of the units being used (meters vs. kilometers). In this case, the options are in kilometers, which is unusual for spot heights.
• Assuming All Peaks Are Similar:
• Not all peaks have similar elevations. Always consider the context of the geographical feature being discussed.
• Ignoring the Highest Value:
• In multiple-choice questions, the highest value is often the correct answer when discussing prominent geographical features like peaks.

Revision Summary

• Spot heights indicate the elevation of specific points on a map, typically in meters.
• The correct answer is often the highest value when discussing significant geographical features.
• Always check the units of measurement to avoid confusion.
• Analyze each option critically to determine why it may or may not be correct based on geographical context.

By understanding these concepts, you can better approach questions related to geographical elevations and spot heights in your exams.
