Answer:
the cascades
Step-by-step explanation:
The correct answer is "The Cascades." The Cascades are a chain of volcanoes in the Pacific Northwest of the United States and Canada, stretching from British Columbia to California. The other choices are not continental volcanic arcs. The Appalachians are a much older mountain range that was formed by the collision of two tectonic plates. The Himalayas are a mountain range that was formed by the collision of the Indian and Eurasian plates. The Alps are a mountain range that was formed by the collision of the European and African plates.
The Cascades are a continental volcanic arc because they were formed by the subduction.
