Questions:
1.
What do the different colors of the plate boundaries in the NASA layer you downloaded mean? In many geological maps or layers, different colors may be used to represent these different types of plate boundaries for clarity. In the file downloaded in the NASA layer, green is used for divergent boundaries, red for convergent boundaries, blue dashed lines for diffuse boundaries and purple for transform boundaries. 2.
How many of your plotted earthquakes are at each type of plate boundary and how many are not at a boundary? (yes, count them and tell me how many) Transform Earthquakes= 21 earthquakes + 8 in close proximity to boundary
Convergent Earthquakes= 1 earthquake
Diffuse Earthquakes= 0 earthquakes
Divergent Earthquakes= 0 earthquakes
No Boundaries= 6 earthquakes
3.
Is this distribution expected? Why or why not?
The earthquake distribution presented is somewhat unexpected. While it aligns with the anticipated high seismic activity along transform boundaries, the single earthquake at convergent boundaries seems relatively low. The absence of earthquakes at divergent boundaries is also atypical, as such regions typically exhibit seismic and volcanic activity. Furthermore, no boundaries with six earthquakes are unusual. When looking closer at the map a
few of these earthquakes occur along an identity convergent boundary in Montana along a mountain range. While ones such as in Kansas are more likely due to faults.
