Worked Solution & Example Answer:What are the main characteristic processes operating at destructive plate boundaries? A - AQA - A-Level Geography - Question 5 - 2018 - Paper 1
Step 1
C. Subduction occurs where two plates converge. Subduction can lead to the formation of features such as deep sea trenches and island arcs.
Answer
At destructive plate boundaries, subduction is the key process that occurs when one tectonic plate moves under another and sinks into the mantle. This process is characterized by the formation of deep ocean trenches and volcanic arcs. As the subducting plate descends, it melts and generates magma, leading to volcanic activity and contributing to the formation of mountain ranges. This intense interaction is also responsible for significant seismic activity, including earthquakes.
