The diagram shows a rift valley formed by the movement of tectonic plates
Which movement of tectonic plates caused the rift valley to form?

Two tectonic plates collided with each other.
One tectonic plate slid under another.
One tectonic plate slid past another.
The movement of the tectonic plates is caused by
the rotation of the Earth.
convection currents in the Asthenosphere
the gravity of the iron-nickel core.
the Moho discontinuity.
Which type of crust is older?
Continental Crust
Oceanic Crust
They are the same age
The crust isn't alive so they don't have an age
What two factors identify what type of crust we have?
Density and location
Buoyancy and Type of material
Density and Buoyancy
Type of material and density
Why does the continental crust float more than the oceanic crust?
The hypothesis that a single large landmass broke up into smaller land masses to form the continents.
continental drift
Sea floor spreading
Asthenosphere
pangea
The process by which new oceanic lithosphere(sea floor) forms when magma rises to Earth’s surface at mid ocean ridges and solidifies
continental drift

Asthenosphere
pangea
The theory that explains how large pieces of the lithosphere called plates move and change shape

Compared to ocean crust near deep-sea trenches, crust near ocean ridges is _____.
younger
older
the same age
magnetically reversed
True or False: The plates are currently moving
What is the difference between magma and lava?
lava is magma but it is on the surface of the Earth
lava is the chamber that magma flows
lava is the Earth's crust
lava has a different chemical composition than magma
Many earthquakes happen along the borders of...
Countries
Tectonic Plates
Climate Zones
Mountains
The surface of Earth is called
crust
core
nucleus
magma
B on the diagram is
Mantle
Inner Core
Outer Core
Crust
The center of Earth is called
Core
Mantle
Crust
San Andreas Fault
What is under the crust?
Magma
Solid Metal
Liquid Metal
Solid Rock
Tectonic Plates move because
Plates float on moving magma.
Plates float on the ocean.
Earthquakes cause plates to move.
The rotation of EArth moves plates.
India colliding with Asia creates the
Himalayan Mountains
Mid Atlantic Ridge
Pacific Ring of Fire
Volcanoes
250 million years ago the continents were
together.
under the ocean.
contracting.
between the oceans.
The place where an earthquake originates inside the Earth's surface is called...
Epicenter
Focus
Underground
Crust
The place on the Earth's surface, above the origin of the earthquake.
Epicenter
Focus
Surface
Crust
Which city is closest to the epicenter?
A
B
C
Which seismogram represents a city that is far from the epicenter of an earthquake?
New York, NY
Nome, Alaska
Guadalajara, Mexico
This is created by earthquakes that occur on the ocean floor.
longshore current
gulf stream
tsunamis
high tide
S-waves can move through which of the following?
Gas
Liquid
Solid
All of these
What is the minimum number of seismograph stations needed to locate an earthquake epicenter?
1
2
3
5
Which wave can travel through all materials?
P - primary
S - secondary
L - Long
Earthquakes generate compressional waves [P-waves] and shear waves [S-waves]. Compared to the speed of shear waves in a given earth material, the speed of compressional waves is
always faster
always slower
always the same
sometimes faster and sometimes slower
The distance between an epicenter and seismograph’s location can be calculated by using the
arrival time of the first P-wave
difference in arrival times between P- and S- waves
amplitude of the p-wave
energy released by an earthquake
Only P-waves were recorded at seismic station C because P-waves travel
only through Earth’s interior, and S-waves travel only on Earth’s surface
fast enough to penetrate the core, and S-waves travel too slowly
through iron and nickel, while S-waves cannot
through liquids, while S-waves cannot
Many earthquakes happen along the borders of...

Tectonic Plates
Climate Zones
None of the above.

When molten rock cools and becomes solid it is called:

Depending on its silica content, lava can be "runny" and flow quickly downslope or "thick" and flow more slowly. This property is called:
density
viscosity
flow rate
