## Step 1The problem is a punctuation question, which is a common type of question in English language and literature. The task is to choose the correct punctuation to complete the sentence in a way that conforms to the conventions of Standard English.## Step 2The sentence is discussing the origin of certain geological structures called arcs. The sentence is divided into two parts: the first part describes the process of how these structures form, and the second part provides additional information about these structures.## Step 3The second part of the sentence is providing additional information about the structures, which is a list of geological terms. This list is not a continuation of the first part of the sentence, but rather a separate piece of information.## Step 4In English grammar, a colon is used to introduce a list, a quote, an explanation, or an example. In this case, the colon is used to introduce a list of geological terms.
