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:

At 30°N and 30°S, the atmospheric circulation (subsidence of air) creates arid conditions, which are characteristic of deserts. Rain forests are near the equator, tundras are at high latitudes, and coniferous forests are in temperate or boreal regions, not 30° latitudes. So the correct biome at 30°N and 30°S is deserts, but wait, the original selected option was C (coniferous forests) which is incorrect. Wait, let's re - evaluate: Wait, the question is which biome is at 30°N and 30°S. Deserts (option D) are found at 30° latitudes due to subtropical high - pressure zones. But maybe there was a mistake in the initial selection. Wait, no, let's check the options again. The options are A: Rain forests (equatorial), B: Tundras (high latitudes), C: Coniferous forests (temperate/boreal), D: Deserts (30° latitudes). So the correct answer should be D. Deserts. But the original selected option was C, which is wrong. Wait, maybe I misread the diagram. Wait, the diagram shows the global atmospheric circulation. At 30°N and 30°S, the Hadley cells' subsidence creates deserts. So the correct answer is D. Deserts. But let's confirm: Rain forests are near 0° (equator), tundras at 60° - 90°, coniferous forests at 50° - 60° (boreal) or temperate, deserts at 30°N/S. So the correct option is D. Deserts. But the user's initial selection was C, which is incorrect. So the correct answer is D. Deserts.

Answer:

D. Deserts
