WebJun 11, 2024 · These rocks found not only in Earth but also in other planets such as Mars or moon. Moreover, these rocks form from the rapid cooling of magnesium and iron-rich lava. Almost 90% of volcanic rocks on Earth’s crust are basalt rocks. Figure 1: Basalt Due to the presence of low silica content, basalt lava has a low viscosity. WebThe subducting plate sinks into the earth's mantle and begins to melt, creating magma that rises to the surface. The magma is thick and viscous, resulting in explosive eruptions that produce composite volcanoes. These volcanoes are characterized by their steep cone shape and explosive eruptions, which eject ash, lava, and pyroclastic material.
