Plate Tectonics
Features found on the ocean floor that delineates subduction zones
What are deep-sea trenches?
The famous volcano in Japan.
What is Mt Fuji?
The energy released by the sudden movement of plates.
What is an earthquake?
A black fine-grained igneous rock
What is basalt?
The plate boundary type at California
What is a transform fault?
The Hawaiian Island chain is an example of this feature.
What is a hot spot?
The famous volcano that destroyed Pompeii
What is Mt Vesuvius?
The point where the energy of an earthquake is released.
What is the focus?
This feature forms by the melting of plate material at a convergent boundary between an ocean and continental.
What is a volcanic island arc?
This plate boundary occurs when magma rises beneath a continent, causing it to become thinner, break, and split apart.
What is a diverging continental-continental plate boundary
Subduction zones have lots of these two phenomena.
What are earthquakes and volcanic eruptions?
Volcano type at converging plate boundaries
What are composite volcanoes?
The earthquake waves that cause the most damage
What are surface waves?
Magma with 60% SiO2
What is Intermediate magma
High fold mountains are formed at this subduction zone.
What an oceanic-continental plate boundary
This is the mechanism for moving continents.
What is seafloor spreading?
Volcano type at diverging plate boundaries
What are shield volcanoes?
The earthquake waves that help geologists determine the epicentre
What are body waves (P and S waves)?
Topographic high features that rise from the seafloor as a long chain of mountains are known as this.
What are divergent plate boundaries?
Mid-ocean ridges are this type of plate boundary.
What are divergent plate boundaries?
The scientists whose evidence supported seafloor spreading.
Who are Vine and Matthews
The volcano type in the Andes Mountains
What are composite volcanoes?
The diagonal line of earthquakes produced at a subduction zone.
What is the Benioff zone?
The zone formed when two continental plates collide.
What is a collision zone?
Boundaries where plates move together are known as this.
What are convergent plate boundaries?
