Question

a soil sample contains 40% silt, 45% sand, and 15% clay. what type of soil do you have? sandy clay loam silt loam loam

Explanation:

Step1: Recall soil triangle usage

To determine soil type, use the soil texture triangle. The three components are silt (40%), sand (45%), and clay (15%).

Step2: Analyze each component's range

• Clay: 15% (between 0 - 27% for loam? Wait, no—check the triangle. Loam has clay 7 - 27%, silt 28 - 50%, sand 26 - 50%.
• Silt: 40% (within 28 - 50% for loam).
• Sand: 45% (within 26 - 50% for loam).

Check the ranges: clay (15%) is between 7 - 27%, silt (40%) between 28 - 50%, sand (45%) between 26 - 50%. This matches loam’s texture ranges.

Answer:

loam
