DUE Tues.
10/29
Getting Started:
1. Go to Mrs. Kent’s teacher website and on the left, click on the link marked “Webquests” then

I. Finding Patterns
WORLDWIDE VOLCANOES
1. Use the image (click the link above) to view where on earth volcanoes are located.
2. Color these areas in RED on the attached world map (last page).
MOUNTAIN RANGES
3. Use the map (click above) to view where earth's major mountain chains are located.
4. Label these areas with green carrots in a chain (^^^^^^) on your world map.
EARTHQUAKES
5. Use the map (click link above) to view where on earth earthquakes happen most often.
6. Color these areas on your world map in YELLOW.
7. What have you noticed about the locations where earthquakes have occurred? Is there a pattern? If so
what is it?
8. How are the locations of earthquakes, volcanoes and mountain ranges related?
9. What regions (coasts, mid-continents, N, E, S, W) of North America and South America show the
greatest amount of crustal activity?
North America:
South America:
10. According to your map, what are the chances that we may experience a major earthquake here in the
Finger Lakes Region? Explain your reasoning.
11. Why do you think the perimeter of the Pacific Ocean is called the "Ring of Fire?"
1
12. a) Compare the red, green and yellow areas on your map to the plate boundaries labeled on page 5 of
your Earth Science Reference Tables. Is there a correlation between the location of plate boundaries and
the location of most earthquakes, mountains and volcanoes?
b) Based on your answer to 12a, what can you infer the cause of most earthquakes,
mountains and volcanoes is?

II. Causes and Effects of Volcanic Eruptions & Earthquakes
VOLCANIC HAZARDS
Use the site (follow the link by clicking on Volcanic Hazards above) to answer the following questions.
12. What materials erupt from a volcano?
FORECASTING VOLCANOES
Use the site (follow the link above) to answer the following questions.
13. What are the warning signs of volcanic eruptions?
EARTHQUAKES
Use the video (click the link above) to answer the following questions.
14. What kinds of destruction were felt in California after the earthquake along the San Andreas fault
(mentioned in the beginning of the video)?
15. What is the Richter scale?
16. What is a seismograph?
CAUSES
(click the link above) to answer the following questions. Choose the "earthquake" symbol (there are four
boxes in the upper left of the interactive) and option/page #2. Then read the caption box.
17. What causes an earthquake on the boundary of a plate?
2
18. What is an "intraplate" earthquake?
EARTHQUAKE SIMULATOR
Use the website (click the link above) to answer the following questions. Fool around with the site for a
while to figure out what type of ground and buildings are most stable.
19. What kinds of ground are the least stable during an earthquake?
20. What are some precautions that can be taken when constructing new buildings that could save
lives and infrastructure in the event of a quake?
III. Addressing misconceptions about Earthquakes and Volcanoes
Look back at the map and questions you have completed while answering the following questions.
TRUE OR FALSE?
21. Earthquakes can occur underwater. ____
22. Earthquakes cannot occur in the middle of a continent. _____
23. More than one earthquake can happen in the same place. _____
24. A volcano that has stopped erupting will never erupt again. ______
25. Volcanic eruptions have warning signs that they might occur soon. ______
26. Earthquakes have warning signs that they may occur soon. _______

IV. Mid Atlantic Ridge
MID OCEAN RIDGE
Use the site (click the link above) to answer the following questions
27. What is the Mid-Atlantic Ridge?
28. If you have not yet colored in the Mid Atlantic Ridge on your map, do so now. It is a mountain range
and should therefore be marked with green carrots ( ^^^^^^^^^) AND LABEL IT!!!
29. The mid ocean ridge is an area where plates are moving _________.

V. Types of Plate Boundaries
30. Use the KEY on the bottom of the map on p.5 of the ESRT to help you describe the following
features/processes. If needed, use your textbook, Google it or look at the map where you have plotted
your earthquakes and volcanoes. Use complete sentences.
a. Plate boundary –
b. Subduction –
31. Fill in the chart below
Type of Plate Boundary
CIRCLE type of
movement
Convergent

mountains, displaced roads, etc.)

32. Use the map on p.5 of the ESRT and place an X in the appropriate box below to identify each location
as a specific type of plate boundary:

need.
THE CRUST

34. How are they different? How are they the same? Fill out the Venn Diagram below with this
information.

35. How are earth’s plates named?
36. Draw the symbol used in the key of the map on p.5 of the ESRT to represent each different type of
plate boundary below (not just arrows, but the lines at plate boundaries on the map)
CONVERGENT:
DIVERGENT:
TRANSFORM:

CONVERGENT BOUNDARIES
37. What are the two kinds of plates that collide at a subduction zone?
38. Draw a subduction zone and label the trench that is created, the plates that are involved (oceanic or
continental), magma, and the feature that is formed. DRAW ARROWS SHOWING THE PLATES' DIRECTION
OF MOVEMENT.
39. What feature is created in the ocean at subduction zones? What feature is created on the land?
40. What happens if two continental plates collide (what topographic feature is created)? Describe the
process.
41. Draw a continental-continental convergent plate boundary diagram. Label the plates and the feature
created. DRAW ARROWS SHOWING THE PLATES' DIRECTION OF MOVEMENT.
DIVERGENT BOUNDARIES
42. What is seafloor spreading?
43. How could a sea be created through the process of rifting?
44. Draw a divergent boundary. Label the plates (oceanic or continental?) and the magma. DRAW
ARROWS SHOWING THE DIRECTION OF PLATES' MOVEMENT.

TRANSFORM BOUNDARIES
45. How is the nature of movement at a transform boundary different than divergent or convergent?
46. Why do earthquakes often happen here?
47. What is another name for a transform boundary?
