What device screws into the soil and churns the soil to be sampled?

• A. Augers
• B. Hand augers
• C. Tube samplers
• D. Gas-powered augers

Answer: (A)

An auger is a tool with a helical screw blade that you rotate to bite into the soil. As it turns, soil is cut and lifted up into the shaft, effectively churning the surrounding material to mix and loosen it for sampling. This rotating, screw-in action is exactly what the description calls for. Hand augers are simply manual versions, while gas-powered augers are engine-driven versions of the same device. Tube samplers, by contrast, are used to extract a cylindrical core without the churn produced by an auger. So the device that screws into the soil and churns it for sampling is an auger.
