What is the 5 description of volcano?
A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. Eruptions can cause lava flows, hot ash flows, mudslides, avalanches, falling ash and floods. The danger area around a volcano covers about a 20-mile radius.
What is lava shooting from a volcano called?
A volcanic bomb or lava bomb is a mass of molten rock (tephra) larger than 64 mm (2.5 inches) in diameter, formed when a volcano ejects viscous fragments of lava during an eruption. They cool into solid fragments before they reach the ground.
