Question

multiple choice question
which series correctly identifies the major parts of a volcano shown in the
diagram?
o a = caldera, b = conduit, c = crater, d = magma chamber, e = vent
o a = crater, b = conduit, c = magma chamber, d = caldera, e = vent
o a = vent, b = crater, c = caldera, d = magma chamber, e = conduit

Explanation:

• Crater: A crater is a bowl - shaped depression at the top of a volcano. In the diagram, A is the crater.
• Conduit: The conduit is the passage through which magma travels from the magma chamber to the surface. So, B is the conduit.
• Magma chamber: The magma chamber (C) is where magma is stored beneath the volcano.
• Caldera: A caldera is a large depression formed when a volcano erupts and collapses. Here, D is the caldera.
• Vent: The vent (E) is the opening through which volcanic materials are ejected.

Answer:

A = crater, B = conduit, C = magma chamber, D = caldera, E = vent.
