QR Challenge: Earthquake/Volcano Review

Created using the ClassTools QR Treasure Hunt Generator

Teacher Notes

A. Prior to the lesson:

1. Arrange students into groups. Each group needs at least ONE person who has a mobile device.

2. If their phone camera doesn't automatically detect and decode QR codes, ask students to

• Download a QR reader (e.g. I-Nigma | NeoReader | Kaywa) onto their mobile devices
• Bring these devices into the lesson.

3. Print out the QR codes.

4. Cut them out and place them around your class / school.

---

B. The lesson:

1. Give each group a clipboard and a piece of paper so they can write down the decoded questions and their answers to them.

2. Explain to the students that the codes are hidden around the school. Each team will get ONE point for each question they correctly decode and copy down onto their sheet, and a further TWO points if they can then provide the correct answer and write this down underneath the question.

3. Away they go! The winner is the first team to return with the most correct answers in the time available. This could be within a lesson, or during a lunchbreak, or even over several days!

Questions / Answers (teacher reference)

Question	Answer
1. Pulls on the crust, stretching rock so it becomes thinner in the middle	tension
2. Landform created by tension	mid ocean ridge
3. Type of plate boundary where tension stress occurs	divergent boundary
4. Squeezes rock until it folds or breaks	compression
5. Landform created by compression	mountain ranges
6. Type of plate boundary where compression occurs	convergent
7. Pushes rock in opposite directions	shearing
8. Landform created by shearing	faults
9. Type of plate boundary where shearing occurs	transform
10. Strain in which a rock is permanently changed	plastic
11. Vibrations in the ground that result from movement along faults, or breaks in Earth’s lithosphere	earthquake
12. Fault caused at a divergent plate boundary	normal fault
13. Two blocks of rock slide horizontally past each other in opposite directions	strike slip fault
14. A strike slip fault occurs at which type of plate boundary	transform
15. Force pushes two blocks of rock together with the rock above the fault moving up	reverse fault
16. A reverse fault occurs at which type of plate boundary	convergent
17. Point beneath Earth’s surface where rock under stress breaks to cause an earthquake	focus
18. Point on the surface directly above the focus	epicenter
19. Move slower than P and S waves, but can produce severe ground movement with a wavelike motion	surface waves
20. Compression waves that travel through solids and liquids, compressing and expanding the material they pass through, temporarily changing volume	Primary waves
21. Only travel through solids and temporarily change the shape, but not the volume of the material they pass through; move slower than P waves	Secondary waves
22. Devices that measure and record ground motion and helps determine the distance seismic waves travel	seismometer
23. Weak spot in earth’s crust where molten material, or magma, comes to the surface	volcano
24. Area where material from deep within the mantle rises then melts, forming magma; a volcano forms above a hot spot when magma erupts through the crust (ex. Hawaiian Islands)	Hot Spot
25. Magma has low silica content, flows easily and erupts quietly with gases bubbling out gently and lava oozing quietly	quiet eruption
26. An eruption that hurls out ash, cinders and magma bombs	explosive eruption
27. Fountain of water and steam that erupts from the ground when buildup of pressure is released	geyser
28. Formed when groundwater is heated by a nearby body of magma or hot rock and eventually rises to the surface to collect in a natural pool	hot spring
29. Geothermal Activity	Occurs when magma, a few kilometers, beneath Earth’s surface, heats underground water
30. Which forces squeeze rocks together, causing them to fold or fracture	compression
31. When rocks deform plastically under compression stresses they	break
32. At which type of plate boundary boundary, do the world’s largest mountains grow	convergent
33. The sudden release of energy stored in rocks creates	earthquakes
34. The main reason there are so many earthquakes around the Pacific ocean basins is	the tremendous number of convergent plate boundaries
35. To find an earthquake epicenter, a seismologist needs to know	the distances from three different seismic stations to the epicenter
36. As stresses build in a region	the rocks deform plastically and then break
37. Mountain ranges rise where there are	compressive stresses
38. A useful earthquake prediction will include the quake's	timing,magnitude
39. One reason fewer people die in developed nations than developing ones in the same magnitude earthquake is	the quality of construction is better
40. Shear stress is the most common stress at transform plate boundaries	true
