The video shows a man transporting a fish from a bucket of nice fish-friendly water to a container filled with an unspecified substance (we know it's not liquid nitrogen, as the temperature is shown at -35 in the beginning, which is too warm for nitrogen to still be in liquid form, no matter the unit).
A subduction zone is formed at a convergent plate boundary when one or both of the tectonic plates is composed of oceanic crust. The denser plate, made of oceanic crust, is subducted underneath the less dense plate, which can be either continental or oceanic crust.
Convergent Plate Boundaries. Convergent boundaries form where two plates collide. These boundaries often form major mountain chains. These boundaries are identified by their high mountains, volcanic island arc chains, and deep earthquakes.An ocean plate converges with a continental plate.ivergent Plate Boundaries. Divergent boundaries can be mid-ocean ridges or continental rift valleys. At these boundaries, two neighboring plates move away from each other. Continental rift valleys are characterized by normal faulting and basalt-rich volcanoes.
