Describe the arrangement and location of earthquakes, volcanoes, and bathymetric features for the following two plate boundaries: 1) near a convergent boundary (oceanic to continental subduction zone) and 2) near a divergent boundary at the mid-oceanic ridge.
Homework Answers
1) At convergent boundary we find,
- Deep-focus earthquakes
- reverse and thrust faults
- island arc and volcanic arcs
- steep slope type bathymetry
- active tectonic boundary
- here crusts destroyed
2) At divergent plate boundary, we found,
- shallow-focus earthquakes
- normal and transform faults
- mid-oceanic ridge system
- passive tectonic boundary
- here new oceanic crust forms
