When a shield volcano erupts, the basalt can flow great distances away from the vent to produce broad, gentle slopes. Shield volcanoes, on the other hand, have gentle slopes that are less than 10° and erupt more fluid lavas called basalt. That’s because the viscous volcanic material doesn’t flow that far from where it is erupted, so it builds up in layers forming a cone-shaped volcano known as a stratovolcano. An eruption of highly viscous (very sticky) magma tends to produce steep-sided volcanoes with slopes that are about 30–35°. Why are there different types of volcano? In this section you can find out the difference between stratovolcanoes and shield volcanoes, as well as lava domes and calderas. Common geometric shapes include books, laptops, frisbees and windows. We often come across different kinds of shapes that are either 2D or 3D. A shape is defined as an object with solid boundary lines, angles, and surfaces. Strictly speaking there are two broad types of volcano, a stratovolcano and a shield volcano, although there are lots of different volcanic features that can form from erupted magma (such as cinder cones or lava domes) as well processes that shape volcanoes.
