WebList three factors that determine the nature of a volcanic eruption. What role does each play? Magma's composition, its temperature, and the amount of dissolved gases it contains - affect the magma's viscosity: the more viscous the material, the greater its resistance to flow Generally, what triggers a Hawaiian-type eruption? WebShield volcanoes build up slowly by the growth of thousands of lava flows that spread widely over great distances, and then cool as thin sheets. On Earth, some of the most massive volcanoes are shield volcanoes. In northern California and Oregon, many shield volcanoes are up to 3 or 4 miles wide and as tall as 1,500 to 2,000 feet.
