Условие
The inhabitants of the Indonesian island of Java were alarmed last May by an earthquake that caused considerable damage in the region around the city of Yogyakarta.
Not far away from Yogyakarta the volcano Merapi has been spewing gas and ashes for several weeks. Experts hold different views about the connection between the two geological phenomena.
Read the article from The Jakarta Post of May 30, 2006 (Section 3, source 1). Study the other sources in Section 3 and answer the following questions.
In source 3, letter ‘A’ indicates the place where the effects of the earthquake were strongest.
1a Which geographical term is used to describe place A? (1m) [1 т.]
1b Which geographical term is used to describe the underground seismic centre of the earthquake. (letter B in source 4)? (1m) [1 т.]
The earthquake was not extremely strong, yet the number of victims was relatively high.
2 Explain two (2) factors that contributed to the relatively high number of victims. (2m) [2 т.]
Write your name and country on worksheet 3.
Java is located on the edge of two geological plates. The cross section of source 4 shows only the upper part of the plates. This same cross section is shown on worksheet 3.
Complete the cross section by drawing the lower parts in the white space.
In your answer:
3a Draw the path of both plates in the underground. (1m) [1 т.]
3b Draw two (2) circles indicating the magma chambers mentioned in source 1. (1 m) [1 т.]
3c Write the following terms in the correct place in the cross section: (1m)
- continental plate
- oceanic plate
- Java Trench [1 т.]
3d Draw two (2) arrows indicating the direction in which both plates move. (1m) [1 т.]
Worksheet 3 ‘Volcano Merapi’ contains a map of the island of Java and the surrounding sea.
4 Draw a line on this map (source 2) indicating the path of the boundary between the oceanic and the continental plates. (1m) [1 т.]
5 Explain why both volcanism and earthquakes occur on the island of Java. (2m) [2 т.]
The nature of volcanism on Java is quite different from volcanism on Iceland. On Java granitic magma is found whereas Iceland has basaltic magma.
6a Use the words ‘high’ and ‘low’ to complete the columns ‘basaltic magma’ and ‘granitic magma’ in the table on worksheet 3. (3m) [3 т.]
6b Based on the properties of the Merapi magma, would an eruption be explosive or quiet? (1m) [1 т.]
Отговори
- 1a epicentre
- 1b hypocentre
- 6b explosive
Решение
1a (1m) epicentre
1b (1m) hypocentre
2 (2m) Two of the following:
Mountainous area which makes rescue and relief operations very difficult.
- It is a densely populated area.
- Indonesia has “a soft state” character: rescue and relief operations are less efficient.
3a (1m)
See example on worksheet 3.
3b (1m)
See example on worksheet 3.
3c (1m)
See example on worksheet 3.
3d (1m
See example on worksheet 3.
4 (1m)
See example on worksheet 3.
5 (2m) The answer should explain how both phenomena are related to colliding plates.
6a (3m) See the table on worksheet 3
- 5 correct answers = 3m
- 4 or 3 correct answers = 2m
- 2 correct answers = 1m
- 1 correct answer = 0m
6b (1m) explosive
Total = 15 marks
