Fragen in diesem Quiz (5)
1Which of the following statements is FALSE?
- AVolcanism and orogeny often occur along subduction zones.
- BBoth crustal extension and crustal shortening can cause the growth of a mountain belt.
- CMassive and major mountain belts, such as the Himalayas, Appalachian, and Andes Mountains were formed by continent-continent collision.
- DOne would not expect orogeny on a planet that has never had plate tectonics.
- EAll of the volcanoes in the Pacific Ring of Fire are associated with subduction of oceanic crust.

- BMany of the terranes farthest to the West were formed some distance away from where they are presently located.
- CSome are pieces of volcanic arcs.
- DSome are pieces of oceanic crust.

4Tsunami can be very devastating with huge loss of life. However, even a major tsunami is unlikely to lead to the extinction of any major group of animals (e.g. rodents, bears, dinosaurs) because tsunami only ______.
- AA. occur in relatively low-latitude areas such as Japan so animals living farther north (or south) wouldn’t have been affected
- BB. affect low-lying coastal areas and it is unlikely that all reproductive members of a group would be restricted to this setting
- CC. affect relatively small areas so entire animal groups would not be wiped out
- DD. occurred in more recent times
- EB,C
- AA. occur in relatively low-latitude areas such as Japan so animals living farther north (or south) wouldn’t have been affected
