Conservative Plate Margins Flashcards
1
Q
Outline conservative plate margins
A
- Two plates move laterally past each other
2
Q
How do hotspot volcanoes form?
A
- Heat from core passed to mantle by conduction
- Heated portions of mantle become less dense and buoyant, rise as plume of magma
- Build up of magma eventually creates volcanic activity on ocean floor
3
Q
How do guyots form?
A
- Above sea level, reducing in height as plate moves away from ridge
- Erosion flattens top of guyot
4
Q
What tectonic features form at conservative plate margins?
A
- Fault lines
5
Q
What hazards occur at conservative plate margins?
A
- Gentle earthquakes, with irregular violent earthquakes
