Match the volcanic component with the function.

ComponentFunction
i. Magma chambera. Pathway for magma to rise
ii. Conduitb. Storage of molten rock beneath the surface
iii. Ventc. Opening through which volcanic gases and materials escape

  • A.i-a, ii-b, iii-c
  • B.i-b, ii-a, iii-c
  • C.i-b, ii-c, iii-a
  • D.i-a, ii-c, iii-b

Answer: B

The correct matching is i-b, ii-a, iii-c.

The magma chamber is the reservoir where molten rock is stored beneath the surface (i-b). The conduit is the pipe through which magma rises from the chamber (ii-a). The vent is the opening at the surface through which lava, gases and other material escape (iii-c).

The trap is mixing up the conduit and the vent: the conduit is the passage, while the vent is its opening at the top.
