1 Convergent Plate Boundaries  plate motions provide the mechanisms by which mantle rocks melt to generate magma. 10.3 Plate Tectonics and Igneous Activity

2 Convergent Boundary Volcano

3 Divergent Plate Boundaries  The greatest volume of volcanic rock is produced along the oceanic ridge system. 10.3 Plate Tectonics and Igneous Activity Lithosphere pulls apart.

4 Intraplate Igneous Activity  Intraplate volcanism =volcanic activity on as tectonic plate away from plate boundaries. 10.3 Plate Tectonics and Igneous Activity Examples include the Hawaiian Islands and the Columbia Plateau.

5 Kilauea, an Intraplate Volcano
