A volcanic arc is chain of volcanic islands or mountains formed by plate tectonics as an oceanic tectonic plate subducts under another tectonic plate and produces magma. There are two types of volcanic arcs: oceanic arcs (commonly called island arcs, a type of archipelago) and continental arcs. In the former, oceanic crust subducts beneath other oceanic crust on an adjacent plate, while in the latter case the oceanic crust subducts beneath continental crust. In some situations, a single subduction zone may show both aspects along its length, as part of a plate subducts beneath a continent and part beneath adjacent oceanic crust.

Arc(s), Ascending and Descending Also Luminous and Shadowy Arcs. A cycle of development, such as that of a planetary chain, can be divided into two halves, the first from the first globe to the middle of the most material globe, and the other extending from this midpoint upwards to the last globe. The first half is the downward or shadowy arc; the second is the ascending or luminous arc. The descending arc represents an involution of spirit and a concurrent evolution of matter resulting in a progressive materialization of spirit and a continuous grossening or concretion of the texture of matter; the ascending arc represents an evolution of spirit and involution of matter, resulting in a progressive dematerialization, spiritualization, or refinement of matter as it increasingly manifests the qualities of spirit. Yet spirit and matter are fundamentally one essence at different stages of development.
