← GeographyWhich risk significantly increases as stalactites grow longer?
A)Drip rate equilibrium decreases gradually
B)Flexural stress at the base increases✓
C)Water acidity levels inevitably diminish
D)Limestone erosion sharply accelerates upwards
💡 Explanation
Increased length amplifies the bending caused by gravity; therefore, flexural stress increases because the stalactite’s weight exerts a greater force on its base, causing possible fracture later on, rather than a slight change within drip rate or acidity levels.
