E) all of the above

Question

Quizplus · Accepted Answer

All of the listed factors (air forced into cracks in rocks, abrasion by water-carried materials, solution of rocks, and crystallization of salts in rock crevices and pores) contribute to coastal erosion in addition to waves. Air forced into cracks in rocks can cause the rocks to fracture and break apart, while abrasion by water-carried materials can slowly wear down the shoreline. Solution can dissolve rocks and minerals, particularly those made of limestone, and crystallization of salts in rock crevices and pores can cause the rocks to expand and contract, eventually leading to their breakdown.
