GEOLOGY

Detailed explanation-1: -A volcanic bomb or lava bomb is a mass of partially molten rock (tephra) larger than 64 mm (2.5 inches) in diameter, formed when a volcano ejects viscous fragments of lava during an eruption. Because volcanic bombs cool after they leave the volcano, they are extrusive igneous rocks.

Detailed explanation-2: -Volcanic ballistic projectiles (VBPs) are centimeter-to meter-sized pyroclasts-i.e., solid to molten rock fragments produced and ejected during explosive volcanic eruptions-that are large enough to move in the atmosphere along ballistic trajectories, mimicking the motion, and often the outcome, of artillery shells.

Detailed explanation-3: -Types of Volcanic Bombs Spindle bombs: Almond-shaped bombs that result from the tearing apart of ribbons of lava either during flight or upon impact with the ground. Ribbon bombs: Elongated ropy-shaped bombs. Cowdung bombs: Very fluid bombs which flatten or splash upon landing.

Detailed explanation-4: -Volcanic bombs formed when a volcano ejects viscous fragments of lava during an eruption and can be thrown many meters to kilometers from an erupting vents. They are a significant volcanic hazards, and can cause severe injuries and death to people in an eruption zone.
