science Flashcards
The physical and
chemical
breakdown of
Earth’s materials
weatheting
The transport of
materials from one
place to another by
water, wind or ice.
erosion
Lava flows to create
new surface material,
and rock debris and
volcanic ash are
deposited on Earth’s surface.
volacin erultions
are built when
continental tectonic plates move and
collide against each other, causing
the plate boundaries to crumple
mountain ranges
A process where Earth material’s
may also be transported and left
behind by water,
wind or ice which
creates a new land.
deposition
These rocks have been elevated,
usually more than 600 m from its
surroundings as tectonic plates move
against each other.
mountains
When rocks are subjected to
very large amounts of stress
that they cannot withstand.
faulting
Highest regions of deformed and
disturbed rocks with steep slopes.
mountains
also help
shape landforms because they
determine the
amount of
available water
that weather and
erode the land.
climatic conditions
Results when rocks are
compressed and bent deep under
Earth’s surface.
folding
Processes that
happen when
stress in rocks
causes them to
deform and
change shape.
foliding and faulting
Elevated surface features that may be
thousands of kilometers long and
hundreds of kilometers wide.
kountain ranges
Hot molten rock or magma
that has erupted onto Earth’s
crust.
lava
An airborne matter from
a volcanic eruption and
can be in any size.
tephra
The longest in the
Philippines and stretches
from Cagayan province in the north and
ends in Quezon province in southern Luzon.
sierra madre
Rock or lava fragments
blasted off in a semi-solid
state and with a diameter
greater than 64 mm
bombs
Opening of the volcano
where the materials are
ejected.
vent
Fragments between 2 and
64 mm in diameter
lapili
Rock or lava fragments
blasted off in a solid state and
with a diameter greater than
64 mm
blocks
Fragments less than 2 mm
in diameter
ash
Lava erupts like
fountains or pours
out like a flood
fissures
A special kind of volcano that is wide, low,
and circular
maar
example of maar
aligator lake
May be formed by the
melting of glaciers,
water currents or
erosion and deposition.
hills
These are squat volcanoes that are much
shorter than volcanoes like Mayon or
Kanlaon.
cinder cones
Some are small and flat while others are
high and rolling.
hills
Long cracks in the ground like some
volcanoes in Hawaii
fissurez
Most famous tourist
attraction and consist of
at least 1268 hills with heights anywhere
between 30 and 50 meters.
choclate hills
Broad, vast flat lands that roll slightly
and elevation changes little.
plains
