The outermost layer of a
planet.
What is the crust?
The layer between the crust and
the outer core.
What is the mantle?
A large fraction of Earth’s
interior. Is made up of
minerals rich in iron, silica,
magnesium, and oxygen. Is
2,500 km thick.
What is the lower mantle?
A liquid layer that surrounds
the inner core.
What is the outer core?
The final layer of the Earth, it
is a solid ball made of metal.
What is the inner core?
A mechanical wave that
propagates along the interface
between differing media, usually
as a gravity wave between two
fluids with different densities.
What is a surface wave?
A seismic wave that moves
through the interior of the Earth
as opposed to surface waves that
travel near Earth’s surface.
What are body waves?
These waves are the fastest
traveling seismic waves and can
travel through solids, liquids and
gases.
What are primary waves?
A type of body wave and is the
first waves from an earthquake to
arrive at a seismograph.
What are P waves?
A seismic body wave that shakes
the ground back and forth
perpendicular to the direction the
wave is moving.
What is a S wave/Shear wave?
A sudden and violent shaking of
the ground sometimes causing
great destruction, as a result of
movements within Earth’s crust
or volcanic action.
What is an Earthquake?
Someone who studies
earthquakes and the
propagation of elastic waves
through Earth
What is a seismologist?
An instrument that measures and
records detail of earthquakes
such as force and duration.
What is a seismograph?
A graph output by a seismograph.
It is a record of the ground
motion at a measuring station as
a function of time
What is seismogram?
A graph of arrival time,
commonly P and S waves,
recorded at different points.
What is a travel time graph?
What is the lithoshpere?
What is the asthenosphere?
What is the mesosphere ?
What is a
rift valley?
These are types of ______.
What is a
fault?
A numerical scale for expressing
the magnitude of an earthquake
on the basis of seismograph
oscillations.
What is the Richter Scale?
A high sea wave caused by an
earthquake, submarine
landslide or other disturbance.
What is a tsunami?
The degree of compactness of
a substance.
What is density?
The quality of being hot;high
temperature.
What is heat?
A continuous mountainous ridge
on the floor of all the major
ocean basins. The rifts at the crest
of these ridges represent
divergent plat boundaries.
What is a midocean ridge?
