Which outcome results when glacial abrasion exceeds weathering?

💡 Explanation

Reduced cirque expansion occurs at the bergschrund because increased glacial abrasion removes rock faster than freeze-thaw weathering. A negative feedback on cirque formation results; therefore expansion decreases, rather than other glacial effects being directly affected.

• Which feedback results when accelerated erosion bares previously deposited alluvial valley fill?
• Which outcome generally occurs due to increased pore water pressure during high intensity seismic activity?
• Which wind shift pattern results from Coriolis effect deflection relative to high pressure systems in northern hemisphere?
• Which mechanism primarily causes cirque expansion in periglacial environments?
• Which geomorphic outcome occurs when slightly acidic groundwater interacts chemically with limestone?
