Earthquake Jeopardy Ride the Wave Plate Tectonic Theory Sliding & Colliding Boundarie s Volcano Facts Monitoring

Ride the Wave 100 Which wave(s) travel through the body of the earth? P and S Waves

Ride the Wave 200 The first wave to arrive. Primary waves

Ride the Wave 300 Which wave is most damaging? Surface waves

Ride the Wave 400 Explain how scientists know the outer core is liquid. S-waves can’t travel through liquid. The S-waves didn’t travel through the outer core. Therefore, the outer core is liquid.

Ride the Wave 500 Explain how you would find the time a p-wave arrives on a seismogram. Find the time the seismogram starts recording. Then count to the p-wave. Each mark to the right represents 1 minute. Each time you drop down a line it represents 30 minutes.

Plate Theory 100 Which part of the Earth has a taffy- like texture and is ductile? Asthenosphere

Plate Theory 200 At what plate boundary is land being destroyed? Convergent

Plate Theory 300 What is the name of the super-continent that was thought to exist 200 million years ago? Pangea

Plate Theory 400 Why is the Atlantic Ocean getting larger? Sea-floor spreading at the mid- Atlantic ridge (divergent boundary)

Plate Theory 500 Name 3 pieces of evidence for continental drift theory. 1.Fit of Continents 2.Rock Evidence 3.Fossil Evidence 4.Climate Evidence

Sliding and Colliding 100 The San Andreas fault is this type of plate boundary. Transform

Sliding and Colliding 200 What is the name of the zone where one plate slips under another? Subduction Zone

Sliding and Colliding 300 When oceanic plate collides with continental plate, what land forms result? Volcanoes and trenches

Sliding and Colliding 400 Which type of earthquake can trigger Tsunamis? Subduction Quake

Sliding and Colliding 500 Explain the difference between the focus and epicenter of an earthquake. The focus is the exact point of the earthquake (underground) and the epicenter is the point on the earth’s surface directly above the focus.

Volcano Facts 100 Name the 3 main types of volcanoes. What is shield, composite, and cinder cone.

Volcano Facts 200 Describe 3 features of a cinder cone volcano. What is smaller than the other volcanoes, created from cinders piling up, often has a crater.

Volcano Facts 300 Explain how volcanic eruptions can affect global weather. What is large quantities of ash are released into the earth’s atmosphere. The ash stays in the earth’s atmosphere, blocks out the sunlight, and lowers the average temperature.

Volcano Facts 400 Name three negative effects of volcanic eruptions. What is ash decreases global temperature, harms planes, bad for respiratory system, causes collapse of buildings, lahars destroy what is in the way.

Volcano Facts 500 Which volcano type is the most explosive? Explain why it is. What is a composite volcano. Composite volcanoes have the most viscous lava (dissolved gases, rock fragments). Since it doesn’t flow, the pressure builds up and is released in an explosive eruption.

Monitoring & Effects 100 A machine used to measure earthquake waves. Seismograph

Monitoring & Effects 200 Name the paper that the waves are recorded on. Seismogram

Monitoring & Effects 300 The amount of energy released during an earthquake is called the _______. Magnitude

Monitoring & Effects 400 Name two ways scientists can tell a volcanic eruption is nearing. What is by monitoring earthquakes, gas emissions, steam, volcano dome growth.

Monitoring & Effects 500 What is a pyroclastic flow? What is a flow of hot ash and gas that rushes down a volcano after an eruption.

Where are the most explosive eruptions located? What causes them to be so explosive? What is around the ring of fire? From subduction. Crust is melted which is high in silica so thick, sticky lava forms leading to more explosive eruptions. FINAL JEOPARDY!
