Echo-sound measurements
GPS( Global positioning system)
Magnetometer measurement
seafloor thickness measurement
Mid-Oceanic ridges are associated with
Convergent Boundaries
Divergent Boundaries
Hot Spots
Transform plate boundaries

continental-to - continental Convergent boundaries
Oceanic- to- Continental
Convergent boundaries
Divergent boundaries
Transform boundaries
Which type of plate is shown in the figure below?
Convergent
Divergent
Subduction
Transform
What happens to Earth's magnetic field over time?
It weakens and eventually disappears
It stays the same
It continually strengthens
It changes polarity
Which of Earth;s outermost layer includes the crust and the upper mantle
Asthenosphere
Mantle
Lithosphere
Outer core
What do the arrows indicate on the Tectonic plate map?
Magnetic polarity
Ocean flow
Plate movement
Volcanic eruption
What evidence helped to support the theory of seafloor spreading
magnetic equality
magnetic interference
magnetic north
magnetic polarity
Which plates tectonic process creates a deep ocean trench
Conduction
Deduction
Induction
Subduction
What causes the plate motion?
Convection in Earths Mantle
Currents in Earth's Oceans
Reversal of Earths Polarity
Rotation on Earth's Axis
New Oceanic crust forms and old oceanic crust moves away from a mid-oceanic ridge during
Continental drift
Magnetic reversal
Normal Polarity
Seafloor Spreading
What is the name of Alfred Wegener's ancient supercontinent called?
Caledonia
Continental Drift
Glossopteris
Pangaea
Which part of the seafloor contains the thickest sediment layer?
abyssal plain
deposition band
mid-oceanic ridge
tectonic zone
What type of rock forms when lava cools and crystallizes on the seafloor?
a fossil
a glacier
basalt
magma
At divergent plate boundaries such as a mid-oceanic ridge, you should expect to find
low viscosity lava and normal faults
low viscosity and reverse fault
high viscosity lava and normal faults
high viscosity lava and reverse faults
High Energy Earthquakes occur
away from the plate boundaries
away from divergent plate boundaries
on convergent plate boundaries
on transform plate boundaries
Large and explosive volcanic eruptions, such as the one shown below, can change climates because
Ash and gas that erupts high into the atmosphere can reflect sunlight
the Magma that erupts is hot
volcanic ash keeps earth from losing its heat
Volcanic mountains block solar radiation
What is an earthquake?
a fault at a convergent plate boundary
a wave of water in the crust
energy released as rocks break and move along a fault
the elastic strain stored in rocks
The figure below shows the Hawaiian Islands, formed by hot spots. Which island is the oldest?
Hawaii
Kaua
Maui
O'ahu
A lag-time graph illustration the relationship between the time it takes a seismic wave to travel from the earthquake epicenter to a seismometer and the
Distance between the earthquakes and the seismometer.
Earthquake intensity
Earthquake magnitude
Size of the fault
Which can show the amount of energy released by an earthquake?
a lag-time graph
Modified Mercalli Scale
Moment Magnitude scale
Richter Magnitude Scale
The location of an earthquake can be determined from seismic data recorded by at least
one seismometer
two seismometer
three seismometer
five seismometers
Along which type of plate boundary do the deepest earthquake occur?
Convergent
Divergent
Passive
Transform
Which state has no active volcanoes
California
Hawaii
New York
Washington
The Richter scale registers the magnitude of an earthquake by determining the
Amount of energy released by the earthquake
amount of ground motion measured at a given distance from the earthquake
descriptions of damaged caused by the earthquake
type of seismic waves produced by the earthquake
which type of fault is shown in the diagram
Normal
Reverse
Shallow
Strike-Slip

ash fall
cinder cone
lahar
pyroclastic flow
Earthquakes occur along the San Andrea's Fault which is an example of this type of plate boundary
Convergent
Divergent
Passive
Transform
Hot Spot Volcanoes ALWAYS
appear at plate boundaries
erupts in chains
form above mantle plumes
Remain active
Where do seismic waves originate.
above ground
epicenter
focus
seismogram
Magma contains (a) gases, including carbon dioxide and sulfur dioxide.
A (a) fault forms when forces pulls rocks apart along a divergent plate boundary
(a) waves travel only through solid material.
Strike- Slip
-slide horizontally past each-other
-Transform plate boundary
Normal
-Pull 2 blocks apart
-block of rock pulls apart THEN down
-Divergent plate boundary
Reverse
-Push 2 blocks together THEN moves up
-Convergent plate boundaries
Divergent Plate Boundary
-2 plates divide
-seafloor spreading
- mid-oceanic ridge
-Rift Valley
Convergent Plate Boundary
-2 plates collide
-subduction
-creates mountain, trenches, volcanoes
Transform Plate Boundary
-2 plates move side to side horizontally
-earthquake
