Topic 1 - Tectonic Processes and Hazards

?
What is the oceanic fracture zone (OFZ)?
The ocean fracture zone is a belt of activity through the oceans along the mid-ocean ridges, coming ashore in Africa, the Red Sea, the Dead Sea rift and California.

What is the continental fracture zone (CFZ)?
The continental fracture zone is a belt of activity following the mountain ranges from Spain, via the Alps, to the Middle East, the Himalayas to the East Indies and the circumscribing the Pacific.
2 of 11
What are secondary hazards of a earthquake/volcano?
Secondary hazards of an earthquake/volcano include landslides and tsunamis.
3 of 11
What is an example of an earthquake that has occurred on an old fault line?
An example of an earthquake that has occurred along an old fault line is the Church Stratton Fault in Shropshire
4 of 11
What are intra-plate earthquakes?
Intra-plate earthquakes are earthquakes that occur in the middle or interior of tectonic plates and are much rarer than boundary earthquakes.
5 of 11
What is a volcano?
A volcano is a landform that develops around a weakness in the Earth’s crust from which molten magma, volcanic rock and gases are ejected or extruded.
6 of 11
What are the three plate boundary types?
Divergent, convergent and conservative are the three types of plate boundary.
7 of 11
What is a divergent plate margin?
A divergent plate margin (most clearly displayed at mid-ocean ridges) have a generally low magnitude, shallow focus and most are under the sea.
8 of 11
What is a convergent plate margin?
A convergent plate margin is an actively deforming collision locations with plate material melting in the mantle, causing frequent earthquakes and volcanoes.
9 of 11
What is a conservative plate margin?
A conservative plate margin neither creates or destroys the lithosphere there is merely sites of extensive shallow focus earthquakes with a considerable magnitude.

What is a hotspot volcano?
A hotspot volcano
