Why do volcanoes often occur along continental-oceanic convergent tectonic plate boundaries?

• The sinking plate melts there, and molten rock escapes upward.

• The plates pull apart allowing magma to rise up in the space formed.

• The crust is thinner there, and molten rock easily escapes to Earth’s surface

• The force of the two plates colliding cracks the crust letting magma seep through.

A student prepared a list of changes that can occur to landforms through volcanic eruptions: 1. formation of new islands 2. formation of new faults 3. addition of new rocks to the land 4. formation of folded mountain ranges Which changes in the student’s list are correct?

• 1 and 2

• 1 and 3

• 2 and 3

• 3 and 4

The diagram shows a belt of volcanoes on the Pacific Plate. Which statement is true about the volcanoes on the Pacific Plate?

• As the Pacific Plate moves, the pressure beneath the individual volcanoes decreases, forcing magma towards the surface and leading to the formation of new volcanoes.

• As the Pacific Plate moves, the volcanoes and the hot spot move together, forming new, larger volcanoes.

• As the Pacific Plate moves, cracks appear in the oceanic crust that fill with water and restrict the formation of new volcanoes.

• As the Pacific Plate moves, the volcanoes move away from the hot spot, forming new volcanoes above the hot spot.

A student prepares a model to show a convergent boundary between two plates, A and B. What would happen if Plate A is a continental plate, and Plate B is an oceanic plate?

• Plate B would subduct beneath Plate A, forming a deep trench.

• Plate A would subduct beneath Plate B, forming an oceanic volcano.

• Plates A and B would collide, forming an oceanic ridge and a volcanic arc.

• Plates A and B would thrust rocks upward, forming a fold mountain.

Volcanic eruptions are catastrophic events that can lead to loss of life. Which measure should people living near the region of an active volcano take to minimize the loss of life?

• Use seismographs to predict volcanic eruptions.

• Install devices to monitor the levels of gases emitted by the volcano.

• Build houses with no vents to avoid contact with lethal gases.

• Build tall houses with steel reinforcements to withstand tremors.

A student reads an article about the 1906 San Francisco earthquake. The student lists several problems that may occur if a region is hit by a massive earthquake: 1. production of acid rain 2. damage of property and lives 3. contamination of air 4. loss of electrical infrastructure 5. creation of tsunami and landslides Which listed problems are likely to happen during a massive earthquake?

• production of acid rain

• damage of property and lives

• contamination of air

• loss of electrical infrastructure

• creation of tsunami and landslides

The map shows the plate boundaries and the locations of active volcanoes present on the various continents. What can be concluded from the data in the map?

• Active volcanoes exist only in regions close to coastlines.

• Active volcanoes are found near the plate boundaries.

• More volcanoes occur in the oceans than on continents.

• More volcanoes occur in larger continents than smaller ones.

The image shows the distribution of plates on Earth and the Ring of Fire labeled. Why are locations on the Ring of Fire more prone to large earthquakes and volcanoes?

• The region is surrounded by continents.

• The temperature in the region is very high.

• The oceanic crust in the region is highly unstable.

• The plates in the region are continuously moving against one another.

The two maps show the locations of plate boundaries on the western seaboard as well as the locations of volcanoes and earthquake epicenters. What can be concluded from the data?

• The region is closer to the oceans, which makes the crust unstable and more prone to volcanoes.

• The region has many active volcanoes, which makes it prone to earthquakes.

• There are several plate boundaries in this region, which makes it prone to earthquakes and active volcanoes.
