To solve this worksheet, we need to match the numbers on the volcano diagram with the correct geological terms. Let's look at each part step-by-step:
1.
Number 1 points to the solid rock layer deep underground that supports everything else. This is the
Bedrock.
2.
Number 2 points to the main vertical tube inside the volcano where magma travels up. This is the
Conduit (pipe).
3.
Number 3 points to a smaller cone built on the side of the main volcano. This is called a
Parasitic cone.
4.
Number 4 points to the layers of material (ash and lava) that make up the body or slope of the volcano. These are the
Layers of Ash (and lava).
5.
Number 5 points to a large blob of magma that has pushed into the bedrock sideways but hasn't erupted. This shape is called a
Laccolith.
6.
Number 6 points to the opening at the very top of the volcano. This is the
Crater.
7.
Number 7 points to the cloud of gas and ash exploding out of the top. This is the
Ash cloud.
8.
Number 8 points to the stream of hot liquid rock flowing down the outside of the volcano. Once it is on the surface, it is called a
Lava flow.
9.
Number 9 points to a smaller pipe branching off the main one to feed the side cone. This is a
Branch pipe.
10.
Number 10 points to the alternating layers of hardened lava and ash that build the volcano's height. These are
Layers of lava.
11.
Number 11 points to a horizontal sheet of magma that has squeezed between layers of rock underground. This is a
Sill.
12.
Number 12 points to the pool of hot liquid rock stored underneath the volcano before it erupts. This is
Magma.
Final Answer:
1. Bedrock
2. Conduit (pipe)
3. Parasitic cone
4. Layers of Ash
5. Laccolith
6. Crater
7. Ash cloud
8. Lava flow
9. Branch pipe
10. Layers of lava
11. Sill
12. Magma
