1.
The Pacific Coasts of Mexico and Central America are geologically related due to
the fact that they are
located in a region where
five tectonic plates interact in the
Mexican Republic: the North American, Cocos, Pacific, Rivera and Caribbean
plates. This region is also known as the “Ring of Fire”.
2.
Due to the San Andreas fault, there are a large number of earthquakes in the Gulf of
California. Because the earthquakes are not deep, this points to a transform
boundary.
3.
The chain of earthquakes are due to the Motagua and Polochic faults in the
region.These faults indicate a transform boundary.
4.
Based on the map the distribution of volcanoes and earthquakes decrease as I move
east from Costa Rica to Panama.
5.
The Nazca Plate is moving in a Northeastern direction.
6.
The shield volcano is the most common one in this region.Based on the text the
magma type consist of many successive flows of low-viscosity basaltic lava but lack
significant amounts of pyroclastic debris.
.
7.
Based on earthquake activity I think that a divergent boundary sits between the
Galapagos and Panama. The plates seem to be moving apart from one another in
this region.
