1. Trenches: Subduction zones typically have deep oceanic trenches formed by the downward bending of the oceanic plate as it subducts beneath the continental plate.
2. Volcanic Arcs: Subduction zones are commonly associated with volcanic arcs, where magma generated by the melting of the subducting plate rises to the surface and forms chains of volcanic islands or mountains.
3. Earthquakes: Subduction zones are known for their high seismic activity, with frequent earthquakes occurring as a result of the subduction process and the interactions between the two tectonic plates.
4. Forearc basins: These are sedimentary basins that form in front of the volcanic arc and are filled with sediments eroded from the volcanic arc and the continental margin.
5. Accretionary prisms: These are tectonic wedges of sediments and rocks that accumulate at the leading edge of the overriding plate as a result of the subduction process.
6. Melange zones: These are complex mixtures of rocks and sediments that form at the subduction interface due to the intense deformation and shearing forces involved in the subduction process.
7. Back-arc basins: These are basin systems that form behind the volcanic arc, often in response to the extension of the overriding plate as a result of the subduction process.
