Explanation written with AI and checked against the answer key

Analyze the question: You are asked to pick the feature that is not commonly found in Nigeria. Note that the question is about "climatic features," so we are looking for the odd one out.

Concept: Nigeria lies in the tropics (West Africa) and has a tropical climate with two main seasons:

  • Rainy season (roughly April to October), with heavy rainfall that can lead to flooding in some areas.
  • Dry season (roughly November to March), with the dry, dusty, cold-morning harmattan wind blowing from the Sahara.
  • High temperatures and strong sun, especially in the north, which gives heat intensity.

Checking each option:

  • A. Flooding: Common, especially in the rainy season in places like Lagos, Lokoja, Yola and Bayelsa. ✔ Found.
  • B. Harmattan: A well-known seasonal feature of Nigeria, from December to February. ✔ Found.
  • C. Heat intensity: Common, especially in the northern part of the country. ✔ Found.
  • D. Rainfall: The main feature of the wet season across the country. ✔ Found.
  • E. Volcanic eruptions: Nigeria is not on an active volcanic or tectonic plate boundary. It has no active volcanoes, and eruptions do not occur here. ✘ Not found.

(Strictly speaking, volcanic eruptions are geological events rather than climatic ones, but this makes it the clear odd one out.)

Answer: E, volcanic eruptions.

Exam tip: In "which is NOT found" questions, test each option against what you know about the place. Nigeria has rain, flooding, harmattan and heat, but it sits in a geologically stable zone, so there are no volcanoes and few major earthquakes. Remember: "Nigeria is wet, dusty and hot, but not volcanic."
