Question

a soil sample has 50% clay, 30% sand, and 20% silt. which type of soil is this? sand loam clay

Explanation:

To determine the soil type, we analyze the percentages: clay (50%) is the largest component, sand is 30%, and silt is 20%. Soil classification is based on the dominant particle type. Since clay makes up 50% (the highest proportion), the soil is clay - type. Sand - dominated soils have more sand (usually >50%), and loam has a balanced mix (typically around 40% sand, 40% silt, 20% clay or similar balanced ratios), which doesn't match here.

Answer:

clay (the option with "clay" as the text)
