Volcanic Bomb | Properties, Formation, Composition ...

Volcanic Bomb Formation. A volcanic bomb is a mass of molten rock (2.5 inches) larger than 64 mm (2.5 inches), which occurs when a volcano removes viscous lava during eruption. They absorb the solid particles before they reach the soil. After the volcanic bombs have been removed from the volcano, extruded magmatic rocks occur due to their cooling.

Igneous rocks — those which originate from magma — fall into two categories: extrusive and intrusive. Extrusive rocks erupt from volcanoes or seafloor fissures, or they freeze at shallow depths. This means that they cool relatively quickly and under low pressures. Therefore, they are typically fine-grained and gassy.
