Question

which of these are typical characteristics of subduction zones?

check all that apply.

• rivers with large deltas
• where oceanic crust meets continental crust
• earthquakes
• mountains formed by the collision of two continents

Explanation:

Analyze subduction zone characteristics

Subduction zones occur at convergent plate boundaries where a denser oceanic plate sinks beneath a less dense plate (either continental or younger oceanic crust). This process generates intense seismic activity (earthquakes) along the sinking slab.

Evaluate the given options

• Rivers with large deltas: This is a surface depositional feature unrelated to tectonic subduction zones.
• Where oceanic crust meets continental crust: This is a classic setting for subduction (oceanic-continental convergence).
• Earthquakes: Subduction zones are highly active seismic regions characterized by shallow to deep-focus earthquakes.
• Mountains formed by the collision of two continents: Continental-continental collisions form massive mountain ranges (like the Himalayas) but do not typically involve subduction of crust into the mantle because continental crust is too buoyant.

Answer:

• Rivers with large deltas
• Where oceanic crust meets continental crust (Correct answer)
• Earthquakes (Correct answer)
• Mountains formed by the collision of two continents
