← HistoryWhich outcome occurs when ancient terrace systems cultivating maize experience prolonged heavy rainfall?
A)Topsoil loss from surface runoff✓
B)Nitrogen fixation by soil bacteria
C)Increased maize kernel size due mutation
D)Enhanced root growth from water saturation
💡 Explanation
When intense rainfall occurs on terraces, surface runoff increases hydraulic shear stress because gravity acts on saturated surface layers lacking root structure, resulting in topsoil erosion. Therefore topsoil loss is likely, rather than nitrogen fixation, increased kernel size, or enhanced root growth each of which require other conditions.
