Which erosion risk increases where deep-rooted shrubland transitions to heavily grazed pasture?

💡 Explanation

Pasture grasses provide less soil structure, therefore compaction increases via bioturbation (reduced burrowing), raising runoff: this is because less water infiltrates dry compact soils, rather than continued root weathering.

• Which risk increases when differential erosion affects coastlines?
• Which thermal consequence arises where oceanic crust subducts beneath continental crust?
• Which weathering consequence results when unconsolidated pyroclastic rock persists?
• Which outcome occurs when high sediment input overwhelms fluvial transport capacity on a low-gradient plain?
• Which outcome occurs when caldera-forming eruptions discharge tephra?
• Which lake-forming outcome occurs when accumulated tephra redirects stream flow?
