Question

label the structure and interior features of this volcano. crater central vent magma chamber dike sill laccolith batholith

Explanation:

Step1: Identify Crater (C)

The crater is the opening at the top of the volcano where eruptions occur, matching label C.

Step2: Identify Central Vent (B)

The central vent is the main passage for magma to the surface, running vertically from the magma chamber to the crater, so B is central vent.

Step3: Identify Magma Chamber (A)

The magma chamber is the large underground reservoir of magma, the broad red area at the bottom (A).

Step4: Identify Dike (E)

A dike is a vertical or steeply inclined igneous intrusion, E is a vertical/steep red feature cutting through layers.

Step5: Identify Sill (G)

A sill is a horizontal igneous intrusion between rock layers, G is a horizontal red layer between other layers.

Step6: Identify Laccolith (F)

A laccolith is a dome - shaped igneous intrusion, F has a dome - like shape pushing up layers.

Step7: Identify Batholith (A - contextually, but A is magma chamber? Wait, batholith is a large mass of intrusive igneous rock. Wait, maybe re - check. Wait, the leftmost large red area (A) could also be part of batholith, but the magma chamber is a part of it. However, following the labels:

• C: Crater (top opening)
• B: Central Vent (vertical tube from C to magma chamber)
• A: Magma Chamber (large underground magma)
• E: Dike (vertical intrusion)
• G: Sill (horizontal intrusion)
• F: Laccolith (dome - shaped intrusion)
• The remaining (maybe the large left - most is batholith, but the labels given: let's match each:

Crater: C (top, where eruption is, with smoke)
Central Vent: B (the vertical pipe from C down to magma chamber)
Magma Chamber: A (the large red area at the bottom, storing magma)
Dike: E (vertical, cuts through layers)
Sill: G (horizontal, between layers)
Laccolith: F (dome - shaped, pushes up overlying layers)
Batholith: The large mass (A is part, but maybe the entire left - most is batholith, but the label A is magma chamber? Wait, maybe the diagram's labels:

So final matches:

• Crater: C
• Central Vent: B
• Magma Chamber: A
• Dike: E
• Sill: G
• Laccolith: F
• Batholith: (the large intrusive mass, maybe A is part, but the labels given: let's list each label:

A: Magma Chamber (or Batholith? Wait, magma chamber is within batholith. But the labels:

From the left list: crater, central vent, magma chamber, dike, sill, laccolith, batholith.

So:

C: Crater (top opening)
B: Central Vent (vertical tube)
A: Magma Chamber (large underground magma)
E: Dike (vertical intrusion)
G: Sill (horizontal intrusion)
F: Laccolith (dome - shaped)
The large left - most (A) is also part of batholith, but the magma chamber is inside the batholith. However, following the labels provided (the left column: crater, central vent, magma chamber, dike, sill, laccolith, batholith), we match each to the diagram:

Crater: C

Central Vent: B

Magma Chamber: A

Dike: E

Sill: G

Laccolith: F

Batholith: The large intrusive body (A is part of it, but the label A is magma chamber, maybe the batholith is the entire large red mass including A)

Answer:

• Crater: C
• Central Vent: B
• Magma Chamber: A
• Dike: E
• Sill: G
• Laccolith: F
• Batholith: A (or the large left - most mass, but A is labeled as magma chamber, so likely A is both magma chamber and part of batholith in this diagram)
