Here’s a breakdown of the landforms and events along with the types of plate boundaries where they can occur:

  1. Ocean Trench

    • Convergent Boundaries: Primarily formed where an oceanic plate converges with another plate (either oceanic or continental), leading to subduction.

  2. New Sea Floor

    • Divergent Boundaries: Created when tectonic plates move apart, allowing magma to rise and solidify at the ocean floor, creating new oceanic crust.

  3. Earthquakes

    • Transform Boundaries: Frequently occur as plates slide past each other, causing friction and stress that is released as seismic energy.
    • Convergent Boundaries: Also common due to the intense pressure and friction at subduction zones.
    • Divergent Boundaries: Can occur as plates move apart and stress builds.

  4. Rift Valley

    • Divergent Boundaries: Formed as continental plates pull apart, leading to the creation of valleys, fault lines, and sometimes new ocean basins.

In summary:

  • Ocean Trench: Convergent
  • New Sea Floor: Divergent
  • Earthquakes: Transform, Convergent, Divergent
  • Rift Valley: Divergent
