11.   However, it will have become clear from the preceding discussion that purely convergent or transform movement is unlikely to occur except along short sections of a plate boundary.

12.   It is more realistic, therefore, to think in terms of a continuum of plate boundary types related to various degrees of convergence and divergence.

13.   Some idea of the variation that may occur along an individual plate boundary can be gained by considering the eastern margin of the Indian Ocean.

14.   Although it must be emphasized that fault-related landforms can be important in areas remote from plate boundaries it will be useful to consider them briefly here.

15.   These margins exhibit a much lower level of tectonic activity than the active margins located along convergent plate boundaries and are consequently termed passive continental margins.

16.   The major differences in rift characteristics relate to their position with respect to plate boundaries and the intensity of volcanic activity associated with them.

17.   A. That we live on a plate boundary.

18.   Guam is at an intersection of the Pacific and Philippine plates where plate boundaries are uncertain and where subduction seems to be minimal and earthquakes are infrequent.

19.   In all types of plate boundaries, earthquakes are common, produced by the jarring and jolting of the moving plates.

20.   This crumpling zone is distinctly different from the three known types of plate boundaries.
