Plate Tectonics
What is Pangea?
The word to describe a calm volcanic eruption
What is effusive?
Type of rock formed when magma/lava cools
What is igneous rock?
What is a seismogram?
The scale used to measure magnitude of earthquakes
What is the Richter scale?
Process by which Atlantic ocean grows due to oceanic plates moving away from one another.
What is seafloor spreading?
The nickname for the location of most of the world's volcano's
Where is the Ring of Fire
Type of plate boundary where two plates collide
What is a convergent plate boundary
With enough force, rocks will change shape, this happens at low levels of stress, and the deformation is temporary.
What is elastic deformation?
The fastest travelling wave of an earthquake that is the first felt by people/seismograms
What is a P wave
The two factors that determine how explosive a volcano eruption is
Viscosity and Gas Content
The two factors that determine the explosiveness of a volcano
What is viscosity and gas trapped?
The natural disaster credited with creating the Hawaiian Islands
What is a volcano?
The scale used to measure what is felt by people/buildings due to an earthquake
What is the Mercalli Intensity Scale
The type of tectonic plate which involves 2 plates sliding past one another
What is transform boundary
Largest continental plate
Pacific Plate
The largest type of volcano made from effusive eruptions
What is a shield volcano?
The type of plate boundary that creates mountains
What is continental-continental convergent boundary
The effect that earthquakes can cause that can make objects sink into the ground or flow like a river
Liquefaction
The two types of surface waves, which cause the most damage to buildings
What is the Love wave and Raleigh waves
3 Natural disasters caused by sudden movement of plate tectonics would be:
What is earthquakes, tsunami, land slides
The two types of transfer of heat that aid tectonic plates in moving?
What is convection and conduction
The point below the earth, where an earthquake takes place.
What is the focus?
These earthquakes rocked a large portion of the NWT and even were felt in central Alberta. Also required: The descriptor word from the Richter scale that describes the magnitude range.
Nahanni Earthquakes (6.2-6.9) Strong Earthquakes
The names of the location of an earthquake above the surface and below the surface
What is the epicentre and focus (hypocentre)
