Revising Dynamic Earth

Use your booklets to answer these questions:


Part I

              1.     Draw a clearly labelled diagram to show the structure of the earth.
       You should include the following labels:

Oceanic crust, continental crust, inner core, mantle, outer core.

2. What is a tectonic plate?

3. What is the relationship between where earthquakes occur and plate boundaries?

4. Draw a clearly labelled diagram of a destructive margin.
You should include the following labels:

oceanic plate, continental plate, mantle, direction the plates are moving, fold mountains, subduction zone, earthquake foci, explosive volcanoes

5. Give an example of a place in the world where there is …
a. A destructive margin
b. A constructive margin
c. A conservative margin
d. A collision zone

6. For a volcanic eruption that you have studied …
a. Name where and when it occurred.
b. Why did it occur?
c. What were the primary effects?
d. What were the secondary effects?
e. What did people do to minimise the effects of future eruptions?

7. Name three positive impacts of volcanic eruptions for the people who live nearby?

8. What piece of equipment measures the strength of an earthquake?

9. What scale do we measure earthquakes on?

10. For an earthquake that you have studied …
a. Name where and when it occurred.
b. Why did it occur?
c. What were the primary effects?
d. What were the secondary effects?
e. What did people do to minimise the effects of future quakes?

11. What is a tsunami?

12. Why do earthquakes and volcanic eruptions seem to cause more damage in LEDCs than MEDCs?



PART II

       1.     Case Studies:  Chose four case studies one earthquake and one volcano each from an MEDC and an LEDC. Copy and complete the table below :


Earthquake
Volcanic eruption
MEDC
(MIC)



LEDC
(LIC)




E.g. Icelandic Volcano for an MEDC eruption; Kobe or Sendai for a MEDC quake; Haiti for an LEDC quake; Merapi for an LEDC eruption. Choose ones that you know best …


For each of your case studies answer the following questions



a.     Where did it happen?
b.     When did it happen (year and perhaps month)
c.     What type of plate margin is it on?
d.     What were the primary effects?
e.     What were the secondary effects?
f.      Important notes: such as …
                                          i.    Why is the event important?
                                         ii.    How did this event help future prediction?
                                        iii.    What could be done to minimise the impact of a similar event in the future?

      2.     Give an example of a place in the world where there is …  
a.     A destructive margin
b.     A constructive margin
c.     A conservative margin
d.     A collision zone

      3.     Name three positive impacts of volcanic eruptions for the people who live nearby?

      4.     What piece of equipment measures the strength of an earthquake?

      5.     What is the difference between the quake’s focus and its epicentre?

      6.     What scale do we measure earthquakes on?

      7.     For an earthquake that you have studied …
a.     Name where and when it occurred.
b.     Why did it occur?
c.     What were the primary effects?
d.     What were the secondary effects?
e.     What did people do to minimise the effects of future quakes?

      8.     What is a tsunami?

      9.     Why do earthquakes and volcanic eruptions seem to cause more damage in LEDCs than MEDCs?
