Identify the parts of a volcano with this educational worksheet.

This is a worksheet designed to teach the parts of a volcano. The task is to match the numbered parts in the diagram with their correct names from the list provided below.

I will identify each numbered part by its location and function, then assign the correct term from the list.

Step 1: Identify the parts based on the diagram

- 1: This is at the very bottom, beneath the volcano structure. It represents the solid rock layer that the volcano sits on. → Bedrock
- 2: This is the main vertical channel running up through the center of the volcano. → Conduit (pipe)
- 3: This is a smaller channel branching off from the main conduit. → Branch pipe
- 4: This is the side of the volcano, showing the buildup of material over time. → Layers of lava
- 5: This is the horizontal intrusion of magma that has pushed between layers of rock. → Sill
- 6: This is the opening at the top of the volcano where material erupts. → Crater
- 7: This is the area around the crater where ash and other materials are ejected into the air. → Ash cloud
- 8: This is the plume of smoke and ash rising above the volcano. → Ash cloud (Note: 7 and 8 both point to the ash cloud; 7 is the immediate area of eruption, 8 is the rising cloud)
- 9: This is a small cone-shaped feature on the side of the main volcano, formed by secondary eruptions. → Parasitic cone
- 10: This is the flow of molten rock coming down the side of the volcano. → Lava flow
- 11: This is the pool of molten rock deep underground. → Magma
- 12: This is a dome-shaped intrusion of magma that has pushed up but not erupted. → Laccolith

Step 2: Match the numbers to the terms

Now I will assign each number to its corresponding term:

- 1 → Bedrock
- 2 → Conduit (pipe)
- 3 → Branch pipe
- 4 → Layers of lava
- 5 → Sill
- 6 → Crater
- 7 → Ash cloud
- 8 → Ash cloud (same as 7, but higher up)
- 9 → Parasitic cone
- 10 → Lava flow
- 11 → Magma
- 12 → Laccolith

Step 3: Final Answer

Here is the completed matching for the worksheet:

- Layers of lava → 4
- Conduit (pipe) → 2
- Lava flow → 10
- Bedrock → 1
- Magma → 11
- Branch pipe → 3
- Crater → 6
- Ash cloud → 7 or 8 (both point to the same feature)
- Layers of Ash → Not clearly labeled; possibly part of 8 or 7
- Parasitic cone → 9
- Sill → 5
- Laccolith → 12

Note:

The term “Layers of Ash” is not clearly assigned to a specific number in the diagram. It may be intended to be part of the ash cloud (7 or 8) or could be an error. In most volcano diagrams, “Layers of Ash” would refer to deposits on the ground, which are not distinctly labeled here.

✔ Final Answer:

- Layers of lava: 4
- Conduit (pipe): 2
- Lava flow: 10
- Bedrock: 1
- Magma: 11
- Branch pipe: 3
- Crater: 6
- Ash cloud: 7 (or 8)
- Layers of Ash: *Not clearly labeled*
- Parasitic cone: 9
- Sill: 5
- Laccolith: 12
