Question

questions 1 through 3 refer to the following. the diagram below is an illustration of global atmospheric circulation. 1 mark for review which of the following is a biome found at 30° n and 30° s as seen in the diagram? a rain forests b tundras c coniferous forests d deserts

Explanation:

To determine the biome at \(30^\circ \text{N}\) and \(30^\circ \text{S}\), we analyze each option:

• Option A: Rain forests are typically found near the equator (\(0^\circ\)), where there is high rainfall due to rising warm, moist air. So, A is incorrect.
• Option B: Tundras are found in high - latitude regions (near the poles or above the tree line in mountainous areas), characterized by cold temperatures and permafrost. They are not at \(30^\circ \text{N/S}\), so B is incorrect.
• Option C: Coniferous forests (taiga) are found in the sub - arctic region (around \(50^\circ - 60^\circ \text{N}\)), with cold climates and coniferous trees. They are not at \(30^\circ \text{N/S}\), so C is incorrect.
• Option D: At \(30^\circ \text{N}\) and \(30^\circ \text{S}\), the air circulation pattern (sub - tropical high - pressure belts) leads to dry conditions. Sinking air in these regions inhibits cloud formation and precipitation, which is favorable for the formation of deserts. So, deserts are a biome found at \(30^\circ \text{N}\) and \(30^\circ \text{S}\).
