7.10B Volcanoes & Hot Spots Research Notes Lesson

Multiple Choice

Which of the following is a direct result of plate tectonic activity?

• Ocean basin formation

• Weather patterns

• Erosion by rivers

• Wind currents

Open Ended

How do plate tectonics contribute to the formation of volcanic eruptions?

Open Ended

How did this volcano form?

Multiple Choice

Which type of plate boundary is associated with the formation of volcanoes at mid-ocean ridges?

• Convergent boundary

• Transform boundary

• Divergent boundary

• Continental boundary

Multiple Select

Select all the correct statements about convergent boundary volcanoes.

• They form when an oceanic plate subducts beneath a continental plate.

• Molten rock wells up to erupt from volcanoes.

• They form only at divergent boundaries.

• Subduction is a key process in their formation.

Fill in the Blank

When one oceanic plate subducts under another oceanic plate, a chain of volcanic islands can form, also called a volcanic ___ arc.

Open Ended

Explain the process by which magma is formed at a convergent boundary between oceanic and continental plates.

Fill in the Blank

At a divergent boundary, convection currents drive plates apart, creating a volcanic vent. Fill in the blank: The plates involved are both ___ plates.

Fill in the Blank

Fill in the blank: Volcanoes form as ___ rises and fills the space that results when plates move apart.

Multiple Choice

What is a divergent boundary volcano and where do they commonly form?

• A volcano that forms at convergent boundaries, commonly found in mountain ranges

• A volcano that forms at divergent boundaries, commonly found at mid-ocean ridges and in places like Iceland

• A volcano that forms at transform boundaries, commonly found in deserts

• A volcano that forms at subduction zones, commonly found near trenches

Open Ended

Explain how hot spots differ from volcanoes that form at tectonic plate boundaries.

Fill in the Blank

Fill in the blank: A hot spot occurs when material deep in Earth's mantle rises and ___, forming magma.

Open Ended

Describe what happens above a hot spot and how it leads to volcanic activity.

Multiple Choice

Which of the following statements about hot spots is correct?

• Hot spots move along with tectonic plates.

• Hot spots occur only at plate boundaries.

• Hot spots are stationary and can cause volcanic eruptions as plates move over them.

• Hot spots do not produce magma.

Multiple Choice

Which of the following statements best explains how hot spots and tectonic plates interact to form volcanic islands?

• Hot spots move with the tectonic plates, creating volcanoes at plate boundaries.

• Hot spots are fixed in place while tectonic plates move above them, forming chains of volcanoes.

• Tectonic plates remain stationary while hot spots move underneath them, creating volcanoes.

• Hot spots and tectonic plates both move together, forming volcanoes randomly.

Multiple Select

Which of the following are true about the formation of the Hawaiian Islands?

• They are formed at a plate boundary.

• They are volcanic islands created by a hot spot.

• They are located in the middle of the Pacific plate.

• They are formed by the movement of the Pacific plate over a hot spot.

Open Ended

Explain why the Hawaiian Islands are located in the middle of the Pacific plate rather than at a plate boundary.

Open Ended

Describe what happens to volcanoes as they move away from a hot spot.

Fill in the Blank

Tectonic plates move, but hot spots ___ move!

'

Fill in the Blank

Older volcanoes are slowly carried ___ from the hot spot.

Multiple Choice

Which of the following best describes the location and significance of Yellowstone National Park in relation to hot spots and supervolcanoes?

• It is located above a subduction zone and is the site of a regular volcano.

• It is located above a hot spot and is the site of a supervolcano.

• It is located above a fault line and is the site of frequent earthquakes.

• It is located above a mid-ocean ridge and is the site of underwater eruptions.

Multiple Select

Which of the following are necessary conditions for the formation of a supervolcano? Select ALL that apply.

• Magma rises into the crust but is trapped.

• Pressure builds up over time as magma pools.

• Magma immediately escapes through the surface.

• Supervolcanoes only form at mid-ocean ridges.

Open Ended

Explain how supervolcanoes form and what causes them to eventually erupt through the crust.

Open Ended

Compare the eruption frequency of supervolcanoes to other volcanoes and discuss why this difference exists.

Fill in the Blank

Supervolcanoes can form at hot spots and ___ zones.

Open Ended

What questions do you still have about how plate tectonics cause volcanic eruptions, including supervolcanoes and hotspots?
