Plate Tectonics

Lesson 07/09/09

Hi 8A,
There are four things to be done this lesson:
1. Research report on seismic activity in Australia
2. Do online activities in preparation for test quiz
3. Do the online test quiz (will be graded immediately)
4. Write down in your record book that you have a test on Wednesday

This lesson is divided in three time slots, so you need to work fast and keep an eye on the time.

From 11:35 till 12:00, work on the research activity:

Research activity:
Open up a Word document and give it the following title: Seismic Activity in Australia, by "Your Name".
Write a short report (no longer than an A4) on the risk of earthquakes and volcanic eruptions in Australia.
Include maps, images and statistics. The sites below will help you:
Email your work to Ms Vanweringh.

From 12:00 till 12:20, prepare for your test quiz by doing the following online activities together:

Then, at 12:20, you will start the test quiz on a site called "Quia".
This quiz will be automatically graded immediately. You can use it as an indication on how you would do on the real quiz on Wednesday. Do the Quia quiz in silence, by yourself. I will also be able to access your grades too, so do your best.

This quiz is an example of the quiz you will be doing on Wednesday 09/09/09 (Your lucky day!) The quiz on Wednesday will contribute to your final grade in this unit. It will be multiple choice with two or three open questions. You will do that quiz on paper, not on the computer.

If you finish this test quiz quickly, please work IN SILENCE on preparing for Wednesday's real quiz:

Thank you for your patience and I will see you on Wednesday! Email me if you have any questions.

Multimedia Activity:

The worksheet will be handed out, if you don't have it you can download it here:
Complete the worksheet using this website:
Note: there will be a test in the last week of term about these terms and concepts so make sure you write everything down very clearly. Write down definitions of all the key terms.

Questions page 106 - 114:

What happens when plates move?
Name three different ways in which plates move and draw the diagram for each type of movement in your workbook, use colour pencils. (Fig. 5.6, 5.8 and 5.9 – make a schematic drawing of 5.9, you don’t have to copy the whole map)

Can you think of better, easier, more descriptive words to describe convergent, divergent and transforming boundaries?
Write down your alternative words for these boundaries

Page 110: Answer this question in your workbook: What do earthquakes and volcanoes have to do with plate tectonics?
Page 112: Answer this question: What is the ring of fire?
Page 114: Answer this question: What is a hot spot?
Draw fig 5.14 in your workbook. Make sure you label everything correctly.


Read page 120 in your text book, about Mt Vesuvius in Italy.
Write a definition in your workbook for the follwing words:

Get your headphones from your locker
Go to this site ( and watch a 10 minute video about the Vesuvius. (Click on "Windows Media" to view)
Watch videos on this page. Write a short paragraph about the 79AD eruption of Mount Vesuvius and its effect on Pompeii. Write this in your workbook. Make sure you give it a good heading.
