Questions and Answers

Which of the following statements about plate boundaries and volcanoes is TRUE?

  • Volcanoes are most common at convergent boundaries due to the high levels of rock melting.
  • Volcanoes are more common at transform boundaries than at divergent boundaries.
  • Volcanoes are more common at convergent boundaries than at divergent boundaries.
  • Volcanoes are most common at divergent boundaries due to the large amounts of magma released. (correct)

Which of the following is NOT a characteristic of the Ring of Fire?

  • It is characterized by high levels of seismic activity.
  • It is formed due to the collision and subduction of tectonic plates. (correct)
  • It is located around the Pacific Ocean.
  • It is a zone of intense volcanic activity.

How are island arcs distinct from hotspots?

  • Island arcs are formed by the rising of magma from the mantle, while hotspots are formed by the subduction of oceanic plates.
  • Island arcs are chains of volcanic islands formed due to subduction zones, while hotspots are volcanoes created by the rising of magma from deep within the Earth. (correct)
  • Island arcs are formed at convergent boundaries, while hotspots are formed at divergent boundaries.
  • Island arcs are characterized by high levels of seismic activity, while hotspots are characterized by volcanic activity.

Flashcards

Volcano Plate Boundaries

Volcanoes commonly occur at convergent and divergent boundaries, but are rare at transform boundaries.

Ring of Fire

A zone around the Pacific Ocean known for its high volcanic and seismic activity due to colliding tectonic plates.

Island Arcs

Chains of volcanic islands formed at subduction zones, with Japan as a prominent example.

Hotspots

Areas where magma rises from deep within the Earth to create volcanoes, like Hawaii.

Physical vs Chemical Properties

Physical properties describe a substance without changing it (e.g., viscosity), while chemical properties describe its reactivity (e.g., how magma interacts with rock).
