Try a few questions
- Practice question 1
A caldera is a large, bowl-shaped depression formed after a significant volcanic eruption, often due to
- A.the collapse of the volcano's summit
- B.the complete filling in of a pre-existing crater with lava
- C.a process entirely unrelated to any volcanic activity
- D.the sudden growth of an entirely new volcanic peak
Show the answer
A. the collapse of the volcano's summit
Calderas typically form when a volcano's summit collapses inward following a major eruption.
- Practice question 2
Earthquake-resistant building design is an important measure used to reduce the risk of
- A.increased property value in earthquake-prone regions exclusively
- B.increased tourism in earthquake-prone regions exclusively
- C.reduced construction costs in earthquake-prone regions exclusively
- D.structural damage and loss of life in earthquake-prone regions
Show the answer
D. structural damage and loss of life in earthquake-prone regions
The primary purpose of earthquake-resistant design is minimizing structural damage and protecting human life.
- Practice question 3
Earthquake-prone zones are often found along
- A.areas with no tectonic activity of any kind whatsoever
- B.the exact centre of a tectonic plate, far from any boundary
- C.the boundaries of tectonic plates, where significant stress can accumulate
- D.a location entirely unrelated to plate tectonics
Show the answer
C. the boundaries of tectonic plates, where significant stress can accumulate
Plate boundaries are specifically where accumulated tectonic stress makes earthquake occurrence most likely.
