Decompression melting increases rapidly beneath icy planets when which outcome occurs?

💡 Explanation

Cryovolcanic dome growth enhances decompression melting because decreased lithostatic pressure lowers melting points, therefore eruptions are more likely rather than methane formation, which would require different conditions.

• Which risk increases when concentrated agricultural runoff occurs above karst topography?
• Which hazard most directly results when large concentrations of tephra are remobilized downslope after initial deposition?
• Which mechanism is responsible for surface rupture along a transform fault boundary?
• Which regional drought risk increases during El Niño?
• Which outcome results when transform fault motion is impeded?
• Which outcome increases when prolonged drought accelerates deflation?
