The triangle below shows a side view of the convergent boundary with the correct scale Use this information along with your answer to question 4 to determine how far theĬonvergent boundary descends as it moves 1 km northward. Use the graph above to determine the approximate latitude of the Aleutian trench atĬalculate the slope of the graph to figure out how quickly the convergent boundary descends asĪ change in latitude of 1 degree corresponds to an approximate 111 km distance along a northsouth line. The Aleutian trench is located where the two tectonic plates meet at the surface of the How does the graph show that the boundary between the Pacific plate and the North American What is the relationship between the depths of earthquake foci and latitude?
