Question

which is one factor that scientists use to classify orders of soil? fertility climate dryness bedrock

Explanation:

Soil classification systems consider various factors. Climate is a key factor as it influences soil formation processes like weathering, leaching, and organic matter decomposition. Fertility is more about soil quality for plant growth rather than a primary classification factor. Dryness is related to climate but not as comprehensive. Bedrock is a parent material but not the main factor for classifying soil orders.
