Which processes are important in the formation of volcanic arcs at the edge of continental plates? Select the two correct answers.(1 point) Responses subduction subduction passing over a hotspot passing over a hotspot uplift uplift plate divergence

Answer 1

The two correct answers are:

1) Subduction: This process occurs when one tectonic plate is forced beneath another plate. In the case of volcanic arcs, oceanic plates typically subduct beneath continental plates, creating a convergent boundary. The descending oceanic plate melts as it encounters higher temperatures and pressure in the mantle, generating magma that rises to the surface and forms volcanoes.

2) Uplift: This process involves the upward movement of Earth's crust, often due to tectonic forces. In the formation of volcanic arcs, the subduction of oceanic plates beneath continental plates can cause the crust to buckle and uplift, leading to the formation of mountain ranges and volcanic arcs.
