Part ii - name the boundary (16 points)

instructions: for questions 1-4, select what kind of plate tectonic boundary you would expect in each of the regions described below.

question 2

a linear region of land with many shallow earthquakes. there is little to no active volcanism. mountains are generally not present or only exist as gentle hills.

select one:

a. transform boundary

b. continent-continent convergent boundary

c. continent-ocean convergent boundary

d. ocean-ocean convergent boundary

e. divergent boundary

question 3

quakes and volcanic activity are continuously found along this mostly underwater boundary. the mountain range it creates is by far the longest on the planet.

select one:

a. transform boundary

b. continent-continent convergent boundary

c. continent-ocean convergent boundary

d. ocean-ocean convergent boundary

e. divergent boundary

question 4

continental arcs are created from the volcanism found here. shallow to deep earthquakes occur along this underwater boundary that also parallels a deep trench.

select one:

a. transform boundary

b. continent-continent convergent boundary

c. continent-ocean convergent boundary

d. ocean-ocean convergent boundary

e. divergent boundary

question 5

shallow to deep earthquakes are found along this underwater boundary that parallels a deep trench. island arcs are created from the volcanism created here.

select one:

a. transform boundary

b. continent-continent convergent boundary

c. continent-ocean convergent boundary

d. ocean-ocean convergent boundary

e. divergent boundary

part iii - relative plate motion (20 points)

instructions: in the map below, you are looking down on three lithospheric plates. the darker plates (plates 1 and 2) are moving in the direction indicated by the white arrows. plate 3 is stationary (not moving). plates 1 & 2 are denser than plate 3. thinking of relative plate motions, choose the appropriate letter(s) from the map to match the tectonic feature listed below. be aware that not all letters will be useable as an answer. note: make sure you have watched the last lecture in this module before starting this part of the assignment.
