prize9-3, Exercise 3: A boundary type (sample: divergent)

Model answer (check the details):

Landscape: a rift valley or a long underwater mountain chain, with young volcanic rock, fissures and hot springs.

Hazards: frequent small to moderate earthquakes and volcanic eruptions, often from fissures rather than single large cones. In Iceland, ash and lava flows affect air travel and settlements.

Example: Iceland on the Mid-Atlantic Ridge, where the rift can be seen on land, or the East African Rift.

Other options: ocean-continent convergence (trenches and volcanic arcs, large earthquakes and tsunamis, as in the Andes or Japan), continental collision (high mountains and strong quakes, as in the Himalaya), transform (strike-slip earthquakes, as in the San Andreas Fault).

Care: name a real place and check it against a source.
