Revision:
We are going to use this time to review your notes in your file ... do not panic if you accidently left all of you notes in school as there is a spare copy in this DropBox folder.If you write your answers in an email then I can give you some quick feedback as I am around for almost the whole holiday period ...
NOTE: If you cannot send diagrams then do not spend hours trying to ... we will look at them when we get back.
Questions:
Plate Tectonics:
Part 1
1. Draw a clearly labelled diagram to show the structure of the earth (PowerPoint is good for this).
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. What piece of equipment measures the strength of an earthquake?
6. What is a tsunami?
7. Why do earthquakes and volcanic eruptions seem to cause more damage in LEDCs than MEDCs?
Part 2
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
|
||
LEDC
|
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?
