Which of the following volcanic forms represents a wide, shallow, and low-relief crater formed by a single explosive phreatomagmatic eruption caused by groundwater contacting hot magma?
A. Cinder cone
B. Maar✓ Correct Answer
C. Shield volcano
D. Composite volcano
💡 Solution & Explanation
A maar is a broad, low-relief volcanic crater created by phreatomagmatic explosions when ascending magma flashes groundwater into high-pressure steam. Cinder cones consist primarily of pyroclastic debris rather than explosive explosion craters. These landforms help geographers study past volcanic and hydrological interactions.
