Which of the following is/are the difference between the crevice and pitting corrosion? Correct Answer Initiation method

Pitting is a special case of crevice corrosion. But in the view of the initiation method, these two-corrosion processes are different. Pitting corrosion is a self-initiating corrosion form, whereas crevice corrosion needs the formation of crevice (a small gap) with differential concentration from outside.
