Where does the formation of a sea cave usually begin?
Answer and explanation
Correct answer: In weak joints and cracks of coastal rocks
A sea cave usually begins where waves encounter a weak joint, crack, or fault in a coastal cliff. Hydraulic pressure forces water into the opening, while wave-borne sediment widens it by abrasion. Continued erosion enlarges the weakness into a cave and may later produce an arch. Therefore option B is correct; the other locations are unrelated to marine cave development.
