Which terrestrial biome is most commonly found around 30° latitude, both north and south of the equator?
A
Tundra
B
Desert
C
Taiga (Boreal forest)
D
Temperate forest
Verified step by step guidance1
Understand the geographical context: 30° latitude, both north and south of the equator, is typically characterized by high-pressure zones where air descends, leading to dry conditions. This is a key factor in determining the biome found in these regions.
Review the characteristics of each biome option: Tundra is found in cold, polar regions; Taiga (Boreal forest) is located in subarctic zones; Temperate forests occur in regions with moderate climates; Deserts are defined by low precipitation and are commonly found in dry, high-pressure areas.
Connect the biome characteristics to the environmental conditions at 30° latitude: The descending air at these latitudes creates arid conditions, which align with the defining features of deserts (low rainfall, sparse vegetation).
Eliminate incorrect options: Tundra, Taiga, and Temperate forests require specific climatic conditions (cold or moderate climates with more precipitation) that are not present at 30° latitude.
Conclude that the biome most commonly found around 30° latitude, both north and south of the equator, is the desert, based on its alignment with the dry, high-pressure conditions typical of these regions.
