Tall trees with buttress roots and evergreen leaves are characteristics features of?

Step 1: Analyze the question The question asks which vegetation zone has tall trees, buttress roots, and evergreen leaves.

Step 2: Explain the concept Vegetation zones differ according to rainfall, temperature, and length of the dry season. The features given point to a place with heavy, year-round rainfall:

• Tall trees: Trees compete for sunlight, so they grow very tall.
• Buttress roots: These are large, wide, plank-like roots at the base of the trunk. They support the very tall trees in shallow, wet soil.
• Evergreen leaves: There is no long dry season, so the trees do not shed all their leaves at once. They keep green leaves throughout the year.

Step 3: Eliminate the options

• A. Temperate grassland: This is mostly grass with few or no trees, so it has no tall buttressed trees. Wrong.
• B. Southern Guinea Savanna: This has scattered trees among tall grasses, and many trees are deciduous (they shed leaves in the dry season). Wrong.
• C. Tropical rain forest: This has very high rainfall, multiple layers of vegetation, very tall evergreen trees, and buttress roots. Correct.
• D. Northern Guinea Savanna: This is drier, with shorter, scattered, mostly deciduous trees and grasses. Wrong.

Step 4: Answer The characteristics described match the tropical rain forest, which is option C.

Exam tip: Link the key words to their zones:

• Buttress roots + evergreen + tall + layers (strata) → Rain forest
• Scattered trees + tall grasses + deciduous + fire-resistant → Savanna
• Short grass + few trees + very dry → Sahel/Sudan or grassland

Typical Nigerian examples of rain forest trees include mahogany, iroko, and obeche, which are found in the southern parts of the country.
