Warm-up: Volcanoes

Front

What is a subduction zone?

Back

A subduction zone is a region where two tectonic plates converge, and one plate slides beneath the other, often leading to volcanic activity.

Front

What type of volcano is characterized by non-explosive eruptions and broad, gently sloping sides?

Back

A shield volcano is characterized by non-explosive eruptions and has broad, gently sloping sides.

Front

How does volcanic activity affect climate?

Back

Volcanic activity can affect climate by releasing large amounts of ash into the atmosphere, which blocks sunlight and can lead to a drop in surface temperatures.

Front

What is a hot spot volcano?

Back

A hot spot volcano is a type of volcanism that occurs far from plate boundaries, typically in the middle of tectonic plates, such as those found in Yellowstone and Hawaii.

Front

In which direction is the Pacific Plate moving, based on the ages of Hawaii's islands?

Back

The Pacific Plate is moving northwest.

Front

What are the main characteristics of a shield volcano?

Back

Shield volcanoes have non-explosive eruptions, produce fountains of lava, and have broad, gently sloping sides.

Front

What geological feature is formed at a subduction zone?

Back

Subduction zones can form deep ocean trenches and volcanic arcs.

Front

What is the relationship between plate tectonics and volcanic activity?

Back

Volcanic activity is often associated with the movement of tectonic plates, particularly at convergent and divergent boundaries.

Front

What is the significance of the Ring of Fire?

Back

The Ring of Fire is a major area in the Pacific Ocean basin where a large number of earthquakes and volcanic eruptions occur, due to tectonic plate movements.

Front

What type of eruptions are typical of stratovolcanoes?

Back

Stratovolcanoes typically have explosive eruptions due to the viscosity of their magma.
