Q2: Lesson 2 | Endogenic Processes Flashcards
Originate within
earth and result
in an increase in
surface relief
endogenic process
Originate within
earth and result
in an increase in
surface relief
endogenic process
bends, cracks, lifts,
and moves Earth’s
rigid outer layer
endogenic process
Compression causes
one block to be
pushed up and over
the other block.
reverse fault
Creates Normal Faults
TENSIONAL TECTONIC FORCES
act in opposite directions and
cause one slab of the rock to be displaced up
and the other slab down
Tensional forces
Tensional stresses
result in the
subsidence of a block
of rock
GRABEN FAULT
the development of
two reverse faults
causing a block of rock
to be pushed up
HORST FAULT
Creates Strike-Slip Faults
SHEARING TECTONIC FORCES
Ground motions of
Earth caused when
accumulating tectonic
stress is suddenly
relieved
EARTHQUAKE
MEASURED BY
RICHTER SCALE
magnitude
MEASURED BY
MODIFIED
MERCALLI
INTENSITY SCALE
intensity
violently blast
molten and solid
rock into the air
explosive
molten
lava pours less
violently as
flowing streams of
lava
effusive
Layers of erupted rock matter that poured
over the landscape when they were molten
lava flows
Gently sloping, dome
shaped cone
SHIELD VOLCANOES
example is hawaii
SHIELD VOLCANOES
Not very explosive,
although still
damaging
SHIELD VOLCANOES
Smallest type of
volcano
cinder cones
Steep, straight
sides and a large
crater in the
center
cinder cones
Effusive or
explosive
COMPOSITE CONES
(STRATOVOLCANO)
Concave slopes
that are gentle
near the base and
steep near the top
COMPOSITE CONES
(STRATOVOLCANO)
Viscous silica
rich magma
pushed into a
vent
plug domes
Dome shaped
summit and
jagged blocks
make up cone on
steep sloping
sides
plug domes
is a depression
created after a
volcano releases
the majority of
the contents of
its magma
chamber in an
explosive eruption
calderas
TAAL
VOLCANO is a
calderas
mayon is a
composite cone
SMITH VOLCANO/ MOUNT
BABUYAN is a
cinder cone
MOUNT PINATUBO is a
STRATOVOLCANO
MOUNT BULUSAN is a
STRATOVOLCANO INSIDE A CALDERA
