Which process creates elevated island ridges as lava cools intensely?

A)Differential thermal contraction
B)Hydrostatic pressure equilibrium
C)Isostatic crustal rebound
D)Sedimentary material lithification

💡 Explanation

Differential cooling on a lava-covered island causes differential thermal contraction, establishing areas of tension concentrated in zones as it solidifies; because this occurs more rapidly at the surface while internal regions are still slightly malleable, elevated ridges form rather than uniform spreading.
