The type of volcano
volcanic morphology due to take place from different magma, which has a different origin. And are composed of different minerals. We classification based on the physical characteristics of the volcano has four types of
lava plateau (Basalt Plateau): the basalt magma broke up the cracks of the crust, then a flood of lava flows on the surface. In the same manner as flooding. When lava cools, it becomes a large volcanic plateau of about 100,000 to 1 million square kilometers, such as the Isle of Skye, England (Figure 5) Figure 5 lava plateau. (Isle of Skye) shield volcano (Shield volcano): formed by basaltic magma has a high viscosity. The lava flowed out to form a plateau. But the viscosity making the magma forming a large volcanoes could rise up to 9,000 meters, but with a slope of only 6-12 ° shield volcano is formed from magma that rises from the hot spot (Hotspot) in its crust. Downstairs (Lower mantle), for example, Moss Kea volcano on Hawaii. The Central Pacific (Figure 6) Figure 6 shield volcano (Moscow Kea).
