← GeographyWhich outcome occurs when pyroclastic surges encounter an inland lake?
A)Formation of transient maar craters✓
B)Deposition of unusually graded bedding
C)Increased silica melt viscosity observed
D)Accelerated dissolution of feldspar minerals
💡 Explanation
Maar craters form due to phreatomagmatic explosions when pyroclastic flows interacts with water triggering rapid vaporization hence the explosion; therefore a shallow crater will result, rather than the other options which concern deposits/lava features independent of water.
