Another Planet's Tectonic Structure

In your role as an exogeophysicist, you have discovered a previously unknown planet orbiting a star 150 light years away in the Hyades star cluster.

It appears a dry planet with little free water, much like Arrakis or Tatooine. Your mission is to chart planets, so you begin by mapping the major physiographic features. You soon decide that the planet has an active core. This leads you to describe the physiographic features in terms of the plate tectonics.

A key step is to provide a sketch of the tectonic features with the names you have chosen. Back at your home planet, your sketch will be evaluated using this rubric:

Another Planet's Tectonic Structure Rubric
Attribute Above Standard (5 pts) Meets Standard (3 pts) Below Standard (1 pt) Subtotal
Plates Six or more named plates with plate directions and felsic masses indicated. Six named plates with plate directions and felsic masses indicated. Less than six named plates or missing plate directions.  
Divergent boundaries Correct symbols, consistent with plate or surrounding plates, some named. Correct symbols, consistent with plate or surrounding plates. Incorrect or missing symbols or inconsistent with plate or surrounding plates.  
Oceanic-oceanic boundaries Correct symbols, consistent with plate or surrounding plates, appropriate island arcs and trenches named Correct symbols, consistent with plate or surrounding plates, appropriate island arcs and trenches indicated. Missing or incorrect symbols, inconsistent with plate or surrounding plates, island arcs and trenches incorrect or missing.  
Oceanic-continental boundaries Correct symbols, consistent with plate or surrounding plates, appropriate mountain ranges, volcanoes and trenches indicated with some named. Correct symbols, consistent with plate or surrounding plates, appropriate mountain ranges, volcanoes and trenches indicated. Missing or incorrect symbols, inconsistent with plate or surrounding plates; mountain ranges, volcanoes and trenches incorrect or missing.  
Continental-continental boundaries Correct symbols, consistent with plate or surrounding plates, appropriate mountain ranges named. Correct symbols, consistent with plate or surrounding plates, appropriate mountain ranges indicated. Missing or incorrect symbols, inconsistent with plate or surrounding plates, mountain ranges missing.  
Transform boundaries Correct symbols, consistent with plate or surrounding plates, some named. Correct symbols, consistent with plate or surrounding plates. Incorrect or missing symbols or inconsistent with plate or surrounding plates.  
Visuals: Well-rendered, enhances product, aids understanding. Pleasing, aids understanding. Missing, irrelevant, distracting, inappropriate.  
Neatness: Exemplary, neat, well planned, enhances display. Neat, aids display. Messy, cluttered, detracts from display.
