2nd Qtr. EQT Review
___________ is the breaking down of rock due to chemical and physical reactions.
Weathering
_______ is the process by which wind, water, ice, and gravity transport materials from one location to another.
erosion
_______ is the process of completely clearing the land
of trees.
deforestation
Classify these actions as destructive or constructive:
1. strip mining 2. mountain building
3. deforestation
1. Destructive2. Constructive3. Destructive
A _______ force is responsible for creating landforms.
constructive
A ________ force is responsible for changing or destroying
landforms
Destructive
_______ are explosive volcanoes made entirely of pyroclastic
materials, they have narrow bases and steep slopes.
Cinder cone
_______ are nonexplosive volcanoes made from repeated layers of runny
lava; they have broad bases and gently sloping sides.
Shield volcano
Where do volcanoes usually form?
Along tectonic plate boundaries
_________ also stratovolcanoes;are the most common type that
forms from explosive eruptions of pyroclastic material followed by
quieter flows of lava.
Composite volcanoes
1. ______ is the name of molten rock within the earth.
2. _______ is the name of molten rock above the surface of the earth.
1. Magma
2. Lava
__________ eruption result in clouds of hot debris, ash, and hot gases being hot from a volcano.
Explosive
_______ very common eruption that produces relatively calm flows
of lava
nonexplosive
Name the type of volcano pictured
Cinder cone
Name the type of volcano pictured
Composite volcano (stratovolcano)
Name the type of volcano pictured
Shield volcano
A type of rock that is formed from cooling magma
igneous
A type of rock that forms under high pressure and high
temperature but is not exposed to enough heat to melt it.
metamorphic
A type of rock that is formed by compaction and cementation of
sediments.
sedimentary
The process by which one rock changes into another.
Rock Cycle
Know this chart:
________ is the point where an earthquake begins beneath the
surface of the Earth.
focus
______ is the point on the Earth’s surface directly above the focus of
the earthquake.
epicenter
How does the intensity of an earthquake change as the distance
from the epicenter increases?
As the distance increases the intensity decreases.
Where do earthquakes and volcanoes most commonly occur?
Along tectonic plate boundaries
Name the fault that matches the boundary:
1. Transform – 2. Convergent –3. Divergent –
1. Strike-slip fault2. Reverse fault3. Normal fault
What type of rocks may contain fossils?
sedimentary
A type of fault that results when rocks are pushed together.
reverse
A type of fault that results when rocks are pulled apart.
normal
A type of fault that forms when rocks break and slip past each
other.
Strike-slip
A surface along which rock layers break and move past one another.
fault
The last seismic waves to arrive and are the most destructive.
Surface waves
The fastest seismic waves… travel through liquids and solids,
P-waves
Created by side-to-side motion…slower than P-waves, but more
destructive
S-waves
The scale used to measure the manitude (strength/damage) of an
earthquake.
Richter Scale
The scale used to measure the intensity of an earthquake – how it
feels to people
Mercalli scale
The theory that states that continents once fit together like a
puzzle…
Continental drift
What part of the Earth is liquid but is forced to act like a solid due to
intense heat and pressure.
mantle
On what part do the tectonic plates move?
asthenosphere
What type of boundary results from the collision of two tectonic
plates?
Convergent boundary
Where would you find a subduction zone- what plate
boundary?
convergent
What layer of the Earth makes up the tectonic plates?
lithosphere
What type of boundary is formed when two tectonic plates slide past
each other horizontally?
Transform boundary
What type of boundary is formed when two tectonic plates pull away
from one another?
Divergent boundary
What was the name of the theoretical ancient supercontinent that contained all of the continents
of Earth?
Pangaea
What type of boundary would be found where sea-floor spreading
occurs?
Divergent boundary
When two underwater lithospheric plates collide and one gets pulled down into the asthenosphere, wat
type of zone is created?
Subduction zone
What type of rock forms at W? X? Y? Z?
W= metamorphicX = magmaY = sedimentaryZ = igneous
What letter identifies the focus?
Z
Name each type of fault
X = transformY = normalZ = reverse
What theory would support why fossils of the same type would be
found on different continents?
Continental drift
What happens at a transform boundary?
Tectonic plates slide past one another horizontally.
How are earthquakes classified?
Strength and Depth
What type of mountain is formed when rocks are under tension?
Fault block mountain
What is the name of the scale used to describe the
hardness of a mineral?
Moh’s Scale of Hardness
If you can see through a mineral it has the special
property of _______. Calcite is an example…
Optics
A mineral that attracts iron has the special property of
________.A mineral that glows under a
black light has the property of ____________.
1. Magnetism2. Fluorescence
A mineral that “fizzes” when acid is dropped on
it has the special property of ______.
Chemical Reaction
_________ is the tendency of some minerals to break along a
smooth, flat surface.
Cleavage
________ is the tendency of some minerals to break unevenly along
curved, irregular surfaces.
Fracture
