Question

1. after the ancient krakatoa destroyed itself in 416 ad, what formed in its throat over time that prevented gases and magma from escaping, making it a time bomb?

a) a layer of sediment
b) a plug of thick, viscous magma
c) a series of mudslides
d) a collapsed crater

1. who was the dutch official and controller of ketimbang who was responsible for reporting large tremors and whose accounts are featured in the documentary?

a) j. sherman
b) captain th. linderman
c) dr. vanderstock
d) villam beijerinck

Explanation:

• Question 5: Indonesia is located at the convergence of the Indo - Australian Plate and the Eurasian Plate (the Burmese continental plate is a micro - plate within the larger context of the Eurasian Plate interaction). The Pacific and Eurasian Plate interaction is more relevant to regions like Japan, the Eurasian and African Plate interaction is in the Mediterranean region, and the South American and Nazca Plate interaction is along the west coast of South America.
• Question 6: Subduction is the process where one tectonic plate is forced beneath another. Continental drift is the movement of continents over geological time, plate spreading occurs at mid - ocean ridges, and transgression is a marine geological process related to sea - level rise.
• Question 7: After a volcanic eruption, a plug of thick, viscous magma can form in the volcanic throat (a lava dome or plug). Sediment layers would not prevent magma and gas escape in the same way, mudslides are a secondary effect of volcanic activity in some cases, and a collapsed crater (caldera) is a large depression and not a “plug”.
• Question 8: Captain Th. Linderman was the Dutch official in Ketimbang who reported tremors. J. Sherman is not relevant in this context, Dr. Vanderstock is not the correct figure, and Villam Beijerinck is a different historical figure (not related to this specific reporting).

Answer:

1. b) The Indo - Australian and Burmese continental Plates
2. a) Subduction
3. b) A plug of thick, viscous magma
4. b) Captain Th. Linderman
