Volcano Parts Labeled: Free Printable Worksheet
This printable can be used as a post-unit assessment for earth science or volcanoes and earthquakes, or can be assigned as a take-home or independent completion activity. An answer key is provided with the volcano parts labeled.
What are the Parts of a Volcano Mentioned in this Worksheet?
- Magma: This is the molten rock material present beneath the Earth's crust. When it rises to the surface, it can lead to the formation of a volcano.
- Lava: This is the molten rock that erupts from a volcano. Once it reaches the Earth's surface, magma becomes lava.
- Vent: This is the outlet or opening through which magma, gases, and other volcanic materials are expelled during an eruption.
- Crater: This is the hollow area or pit at the top of a volcano. It is formed by the collapse of material during volcanic activity. It is through the crater that lava, ash, and gases are expelled during an eruption.
- Cone: This is the visible, outer part of the volcano that is often shaped like a funnel. It is built up from the hardened lava, ash, and other materials that are ejected during eruptions.
- Dust, Ash, and Rock: These are the solid particles that are ejected during a volcanic eruption. Dust is the finest material, while ash consists of slightly larger, often sharp fragments. Rocks, or volcanic bombs, are the largest materials expelled and can range in size from small pebbles to large boulders. All these materials contribute to the buildup of the volcanic cone and can be spread over large areas during an eruption.
