Why Lesson Planet?
The tectonic processes that have resulted in the formation of the Marianas Arc, and the Marianas Trench are explored. Groups of pupils access websites that give them a wealth of information about these formations. Each group must prepare a three-dimensional relief map of the Marianas Arc, or a model of a volcano found in the Marianas Islands. This impressive plan should lead to a much greater understanding of the earth's tectonic processes.
