Final answer:
Plate tectonic boundaries are categorized by their movements as transform (shearing motion), divergent (plates moving apart), and convergent (plates moving towards each other with possible subduction).
Step-by-step explanation:
The boundary labels for the plate tectonic movements are as follows: the arrow for transform/faulting represents shearing motion where tectonic plates slide past each other horizontally. The arrow for convergent/flopping demonstrates plates moving towards each other, which can lead to one plate sliding beneath another in a process known as subduction.
The arrow for divergent/seafloor spreading indicates where tectonic plates are moving away from each other, and new crust is being formed as magma rises from below the Earth’s surface. Lastly, the arrow for convergent / subduction shows where an oceanic plate is forced below another plate into the mantle.
Creating a subduction zone that is often characterized by deep trench formations and can also generate volcanic activity. By examining earthquake and volcano maps, the Scotia plate shows these types of boundaries, as well as elevations that correspond to the different types of crust involved.
