- magma chamber: The large, underground pool of molten rock located at the base of the volcano.
- crater: The bowl-shaped opening at the top of the volcano from which lava and ash erupt.
- lava flow: The stream of molten rock that flows down the sides of the volcano during an eruption.
- ash cloud: The large plume of ash and gas ejected into the atmosphere during an eruption.
- secondary vent: A smaller opening on the side of the volcano through which magma can erupt.
- volcanic bomb: The large, solidified chunks of lava being thrown into the air from the crater.
- throat: The narrow channel connecting the main vent to the crater at the surface.
- main vent: The primary, central conduit through which magma travels from the magma chamber to the surface.
- fumarole: The small vent on the side of the volcano releasing steam and gases.
- layers of lava and ash: The alternating strata of solidified lava and deposited ash that build up the volcano's cone over time.
Parent Tip: Review the logic above to help your child master the concept of parts of volcano worksheet.
