Contrast the physical features of the high and low islands of the pacific. why would geographers separate the pacific islands into these two categories?

The Pacific high islands were formed by seismic activity. Continental islands and oceanic islands were formed by volcanic activity. High islands often have fertile soils and lush rainforests. In contrast, low islands often were formed by coral growth. They are often less fertile than the high islands. Some low islands lack freshwater sources.
