How does a lapies or clint-and-grike surface form?
Answer and explanation
Correct answer: By solution widening cracks on a limestone surface
Lapies, also called clints and grikes, are characteristic karst features on exposed limestone. Rainwater, made slightly acidic by dissolved carbon dioxide, enters joints and chemically dissolves the limestone. Continued solution widens and deepens the cracks, leaving blocks or clints separated by grooves called grikes. Thus option C is correct; the other choices describe glacial, coastal, or fluvial deposition rather than limestone solution.
