Question

a ______ zone is the place where two lithospheric plates converge, one riding over the other. most volcanoes on land occur parallel to the boundary between the two plates.
○ volcano
○ continental
○ subduction
○ convergent

Explanation:

To solve this, we analyze each option:

• "Volcano" is a landform, not a zone where plates converge. Eliminate.
• "Continental" refers to continental plates or crust, not a zone of convergence. Eliminate.
• "Subduction" zone is where one lithospheric plate (usually oceanic) subducts (rides over) another (usually continental) as they converge. This matches the description.
• "Convergent" is a plate boundary type, but the description specifies one plate riding over the other, which is subduction (a type of convergent boundary process). "Subduction" is more specific to the described process.

Answer:

C. Subduction
