4.3 Types of Volcanoes – Physical Geology

WebNo, technically it is not possible to freeze lava. Lava is a molten rock that is produced when magma, which is the liquid rock found beneath the earth’s surface, erupts from a volcano or fissure. Lava is formed from a range of minerals and elements such as silicon, aluminum, magnesium, iron, and calcium, which have a high melting point. WebShield Volcanoes Shield volcanoes get their name from their shape—a huge shield laid on its side. Figure 8.23 shows the Mauna Loa Volcano. You can see that shield volcanoes do not have the steep mountainous sides of composite volcanoes. They have a very wide base and are much flatter on the top than composite volcano. WebMost are mafic and form from the gas-rich early stages of a shield- or rift-associated eruption: Eve Cone, northern B.C. Composite volcano: Almost all are at subduction zones: Medium size (1000s of m) and moderate … painshill park theatre
