Understanding Disruptions

Comparing and Contrasting Earthquakes and Volcanic Eruptions

​Review - Similarities

• Earthquakes and Volcanic Eruptions are both disruptions.

• Disruptions are temporary changes to the geosphere.

• Earthquakes and Volcanic Eruptions happen at plate boundaries.

• They mostly happen near the Pacific Ocean.

• Both disruptions can damage infrastructure, like buildings, roads, and bridges.

​Review - Differences - Causes

• Earthquakes happen at transform boundaries, but Volcanic Eruptions happen at convergent and divergent boundaries.

• In an Earthquake, energy rises to the surface, but in a Volcanic Eruption, magma rises to the surface.

  ​

Dropdown

​

Select answer

are most likely to happen at ​ transform boundaries,

but ​

Select answer

are most likely to happen at convergent and divergent boundaries.

Multiple Choice

At this boundary, two plates rub against each other until they release a lot of energy.

• Convergent

• Divergent

• Transform

Multiple Choice

At this boundary, the magma rises and pushes the plates apart.

• Convergent

• Divergent

• Transform

Multiple Choice

At this boundary, one plate sinks, melts to form magma, and then rises up through the volcano.

• Convergent

• Divergent

• Transform

Dropdown

During an Earthquake, ​

Select answer

rises from underground to the surface,

but during a Volcanic Eruption ​

Select answer

rises from underground to the surface.

​Review - Differences - Classification

• Earthquakes are classified based on their magnitude, on a scale from 1-10.

  • They are measured using a seismograph.

• Volcanic Eruptions are classified based on the time since the last event.

  • Active - Will erupt again soon

  • Dormant - May erupt again

  • Extinct - Will not erupt again

    ​

Multiple Choice

To study Earthquakes, scientists use a tool called a ____.

• Seismograph
