Which outcome occurs when pyroclastic surges encounter an inland lake?

💡 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.
