Question

Explain the formation of thousands of islands in indonesia and philippines island groups

Answer 1

Both Indonesian and Philippines archipelagos are a result of a combination of volcanic activity and tectonic plate movement. Both islands have been hotbeds of volcanic and seismic activity due to the convergence of continental plates. The islands are initially cause by the volcanoes, and later the shifting of tectonic plates results in their consolidation as a grouping of small islands in a relatively small area. Underwater volcanoes lead to seepage of magma onto the sea, thereby creating rock formation. Continual release of magma causes these rock formations to emerge onto the surface of the sea, thus creating an island.
