A Tectonic
Re-plate-tionship
Re-plate-tionship
These can be "built" as a result of convergence between two continental plates (and subsequent buckling).
What are mountain ranges?
The Earth's core is mostly made of these two magnetic metals.
What are nickel and iron?
This is the scale from 1 to 10, used to express the strength/energy an earthquake releases.
What is the Richter scale?
This is the first thing you should do if you think a tsunami is going to hit.
What is get out of the water & get to higher ground immediately?
Every layer of the Earth is part of this "sphere" of the Earth. (Hint: Don't think about oceans or groundwater; they're in a different "sphere.")
What is the geosphere?
A fault is this type of plate boundary.
What is a transform boundary?
This is comprised of the rigid mantle and crust.
What is the lithosphere?
You can give this title to a scientist that studies earthquakes.
What is a seismologist?
This is the scale used to represent earthquake damage.
What is the Mercalli scale?
This is the density range of the crust.
What is 2.7-3.0 g/cm3?
This type of boundary is present at/above subduction zones.
What is a convergent boundary?
This layer is also called the asthenosphere.
What is the plastic mantle?
True or False: Earthquakes can occur at plate boundaries in which movement is happening, as well as at faults (which are further inland).
What is True?
True or False: Liquefaction occurs when a tsunami is divided into fractions.
What is False?
(Liquefaction is when a material moves like a fluid/liquid. E.g. sand with seismic waves moving through it)
Tectonic plates moving over these specific points in the plastic mantle can cause volcanic eruptions.
What are hot spots?
Divergent boundaries are responsible for this two-word phenomenon at the bottom of a large body of water, such as an ocean.
What is seafloor spreading?
Between granitic continental crust and basaltic oceanic crust, this is the less dense type of crust.
What is continental crust?
These are the full names of the two types of seismic waves.
What are primary waves and secondary waves?
(OR What are primary waves and shear waves?)
(Half-credit: What are P-waves & S-waves?)
Tsunami wave speed decreases as distance from the epicenter increases. This is the type of relationship these two variables would have if they were graphed together.
What is an indirect/inverse relationship?
It's the true origin site of an earthquake, found directly under the epicenter on the Earth's surface.
What is the focus?
Between the Indian-Australian Plate and the Fiji Plate, this plate is the one that is subducting.
What is the Indian-Australian Plate?
This layer of the Earth is completely liquid.
What is the outer core?
At this type of fault, the block of crust above the fault moves up in relation to the block below the fault.
What is a reverse fault?
(What is reverse?)
The damage done to a building by an earthquake is dependent on several factors, including: intensity, a structural design, duration of vibrations.
This is the one major factor not already listed.
What is (the nature of) the material on/in which the structure is built?
(Half-credit for any of these examples: Bedrock? Landfill? Sediments/Sand?)
An earthquake with a Richter scale reading of 5.1 is this much more powerful than an earthquake with a Richter scale reading of 2.1.
What is 1,000 times more powerful?
(What is 103 times more powerful?)
