Verified step by step guidance1
Understand the concept of biomes: Biomes are large ecological areas on Earth's surface, defined by specific climate conditions, plant communities, and animal species. Climate is the primary factor influencing biome distribution.
Identify the key climate factors: The two major climate features that define biomes are average annual precipitation and average annual temperature. These factors determine the types of vegetation and organisms that can thrive in a biome.
Eliminate irrelevant options: Altitude, soil pH, and wind speed are environmental factors that can influence local ecosystems but are not the primary determinants of biome classification.
Focus on the correct answer: Average annual temperature, along with average annual precipitation, directly impacts the climate and thus defines the biome type (e.g., tundra, desert, rainforest).
Conclude: The correct answer is 'average annual temperature,' as it is one of the two major features that define biomes on Earth, alongside average annual precipitation.
