← GeographyWhich consequence results when increased earthworm activity occurs?
A)Accelerated mineral soil horizon mixing✓
B)Reduced surface runoff infiltration rates
C)Decreased topsoil organic matter decomposition
D)Diminished subsoil aeration and drainage
💡 Explanation
Increased earthworm activity leads to accelerated mineral soil horizon mixing because bioturbation physically redistributes soil components; therefore horizon textures become increasingly homogenized, rather than remaining highly stratified.
