Which term names the five factors of soil formation?

Soil texture Five factors of soil formation Soil color Soil profile

Correct Answer:

Five factors of soil formation

Explanation:

The main idea here is recognizing the label that names what shapes how soil forms. In soil science, soil development is governed by five factors: climate, organisms, relief (topography), parent material, and time. The term that names this whole framework is “the five factors of soil formation,” which is why it’s the best answer—it’s the specific label for those five influences. Other terms describe particular soil properties or features—texture (particle size), color, and the soil profile (the vertical horizons)—and do not name the entire set of factors driving soil formation.
