Resources Randoms!
The study of the large-scale
processes that collectively
deforms the plates that make
up Earth’s crust.
What is Tectonics?
The theory which proposes that
Earth’s outer shell consists of
individual plates that interact in
various ways.
What is Plate Tectonics?
Numerous rigid sections of the
lithosphere that move as a unit
over the material of the
asthenosphere.
What are Plates?
A concentration of heat in the
mantle, capable of producing
magma, that in turn extrudes
onto Earth’s surface. This
‘spot’ can create intraplate
volcanism.
What is a hotspot?
A mass of hotter-than-normal
magma that ascends toward
Earth’s surface, where it may
lead to igneous activity on a
plate.
What is a Mantle Plume?
The process in which the natural
remnant magnetism in rock
bodies can help determine the
location of the magnetic poles.
What is Paleomagnetism?
The idea that the magnetic poles
have ‘wandered’ through time.
What is Polar Wandering?
The type of magnetism in which
rocks exhibit the same
magnetism as the present
magnetic field.
What is Normal Polarity?
The type of magnetism in which
rocks exhibit the opposite
magnetism to the present
magnetic field.
What is Reverse Polarity?
The theory which states that
Earth’s North and South poles
switch direction periodically.
What is Magnetic Reversals?
The endowment of materials held
in reserve that are useful to
humans and are ultimately
available commercially.
What are Resources?
A resource that is virtually
inexhaustible or that can be
replenished over a relatively
short time span.
What is a Renewable
Resources?
A resource that forms or
accumulates over such a long
time span that it must be
considered as fixed in total
quantity.
What is a Non-renewable
Resource?
A mineral resource that is not a
fuel and is not processed for the
metals it contains. In fact these
minerals are non-metallic.
What are Non-metallic mineral
resources?
Daily Double: Random Question
People at parties will NOT get
these jokes...
That’s OK because igneous is
bliss!
Mountains that are formed, in
part, by igneous activity
associated with the subduction
of oceanic lithosphere beneath
a continent.
What are Continental Volcanic
Arcs?
A mechanism that contributes
to plate motion in which cool,
dense oceanic crust sinks into
the mantle and « pulls » the
trailing lithosphere along.
What is Slab-pull?
A mechanism that may contribute
to plate motion. It involves the
oceanic lithosphere sliding down
the oceanic ridge under the pull
of gravity.
What is Ridge-push?
This is a proposed driving
mechanism for plate
movement, caused by unequal
heating in Earth’s mantle.
What is Mantle Convection?
Watson: Holmes! What kind
of rock is this!
Holmes: Sedimentary, my dear
Watson.
