Which of the following geological features forms at a subduction zone between an oceanic and a continental plate?

Question

Question 9 options:

A)

Mid-ocean ridge

B)

Magnetic anomalies

C)

The lithosphere

D)

Continental shelf

Answer 1

At a subduction zone between an oceanic and a continental plate, the geological feature that forms is typically a trench. However, out of the options provided, none specifically refers to a trench. None of the options directly describe features formed at a subduction zone; however, I can clarify the options:

A) Mid-ocean ridge - This is associated with divergent boundaries, not subduction zones.

B) Magnetic anomalies - These are related to the age of the ocean floor and the process of seafloor spreading, not specifically to subduction zones.

C) The lithosphere - This includes both oceanic and continental crust, but is a broader term that does not specifically describe a feature at subduction zones.

D) Continental shelf - This is the submerged border of a continent, not directly related to the subduction process.

Given these choices, it appears none directly answer the question correctly. However, if you were to refer to features formed by the process involving subduction, Option C (The lithosphere) might be the closest in a broader sense, as it involves both subducting oceanic plate and continental plate.
