Final answer:
The angle of subduction affects the distance volcanoes form from the trench in a subduction zone. Steeper angles of subduction result in volcanoes being closer to the coastline.
Step-by-step explanation:
The angle of subduction affects the distance volcanoes form from the trench in a subduction zone. When the angle of subduction is steeper, the volcanoes are typically closer to the coastline.
This is because a steeper angle of subduction allows the subducting plate to sink more quickly into the mantle, leading to partial melting and volcanic activity closer to the trench.
