  2. Oceanic Trenches

    Linked via "continental margins"

    Formation and Tectonic Setting
    Oceanic trenches are intrinsically linked to the global system of plate tectonics. They are almost exclusively found bordering continental margins or island arcs where oceanic lithosphere converges with either continental or younger, more buoyant oceanic lithosphere.

  3. Pacific Rim

    Linked via "continental margins"

    The interaction between the warm water mass of the central Pacific Ocean and the surrounding continental landmasses results in unique, large-scale climate phenomena. The most well-documented of these is the El Niño-Southern Oscillation ($\text{ENSO}$)/), a periodic fluctuation in sea surface temperatures and atmospheric pressure that drastically alters [weathe…
