GEOLOGICAL PROCESSES (LESSON 4) Flashcards
refers to the different processes that happened
geological processes
takes place on earth’s surface, is very destructive
exogenic processes
takes place beneath the surface of the earth, focuses on formation or creation
endogenic processes
types of exogenic processes
weathering, soil erosion, mass wasting
the process that breaks down rocks into smaller pieces.
weathering
types of weathering
physical/biological, chemical
happens when rock is physically broken into smaller pieces.
physical weathering
factors of physical weathering
Ice wedging, growth of plants, wind, animals, heat from the sun
is the process of breaking down rock through chemical changes
chemical weathering
factors of chemical weathering
water, C02, rusting, acids from remains
DEFINE SOIL EROSION
THOSE ROCK PARTICLES, GET CARRIED AWAY BY WIND, WATER, ICE AND GRAVITY
DEFINE MASS WASTING
IS THE MOVEMENT OF ROCK, SOIL, AND REGOLITH DOWNWARD DUE TO THE ACTION OF GRAVITY
MASS WASTING ARE TRIGGERED BY?
- OVER-STEEPED SLOPE
- WATER
- EARTHQUAKE
- VEGETATION REMOVAL
WHAT ARE THE CLASSIFICATION OF MASS WASTING
-SLUMP
-DEBRIS SLIDE
-EARTHFLOW
-DEBRIS FLOW
-MUDFLOW
-ROCK FLOW
DEFINE ENDOGENIC PROCESSES
THIS PROCESSES TAKES PLACE BENEATH THE SURFACE OF THE EARTH.
(TRUE OR FALSE)
EXOGENIC PROCESSES FOCUSES ON FORMATION OR CREATION
FALSE, ITS ENDOGENIC PROCESSES
WHAT ARE THE TWO TYPES OF ENDOGENIC PROCESSES?
FORMATION OF MOUNTAIN, FORMATION OF VOLCANO
WHAT ARE MOUNTAINS?
-PRODUCES TWO CONTINENTAL PLATES
-USUALLY IN THE FORM OF A PEAK
-PROVIDES HABITAT
WHAT ARE THE PRINCIPLES OF MOUNTAIN BUILDING?
CRYSTAL UPLIFTING, ROCK DEFORMATION
DEFINE CRYSTAL UPLIFTING
AS THE EROSION DECREASES, THE CRUSTAL THICKENS OF THE MOUNTAIN BEING FORMED WILL INCREASE.
DEFINE ROCK DEFORMATION
ROCK LAYERS ARE BEING DEFORMED (BREAKAGE)
〜〜〜 IDENTIFY WHICH IS SYNCLINE AND ANTICLINE
UPPER CURVE IS ANTICLINE
I
〜〜〜〜〜〜
I
LOWER CURVE IS SYNCLINE
TYPES OF ROCK DEFORMATION
FOLDS
FAULTS
JOINTS
DEFINE FOLDS
DEFORMED LAYERS CAUSED BY HORIZONTAL COMPRESSION
DEFINE FAULTS
CAUSED BY THE MOVEMENTS OF THE PLATES

TINAMAD NAKO:)
DEFINE JOINTS
IT HAS NO PLATE MOVEMENT
TYPES OF MOUNTAIN
FOLDED MOUNTAINS, VOLCANIC MOUNTAINS, FAULT-BLOCK MOUNTAINS, DOME MOUNTAINS
DEFINE FOLDED MOUNTAINS
THE LARGEST AND MOST COMPLEX MOUNTAIN FORMED.
DEFINE VOLCANIC MOUNTAINS
FORMED FROM THE GIGANTIC PILES OF LAVA
DEFINE FAULT BLOCK MOUNTAINS
FORMED MOSTLY BY NORMAL FAULTS
DEFINE DOME MOUNTAINS
A MOUNTAIN THAT STOPPED GROWLING/ERUPTING
DEFINE VOLCANOES
ANY LANDFORM CREATED FROM MOLTEN HOT AND GASEOUS MATERIALS ARE VOLCANOES.
1 CONTINENTAL PLATES COLLIDES 1 CONTINENTAL PLATES = ?
MOUNTAIN
1 CONTINENTAL PLATE COLLIDES 1 OCEANIC PLATES = ?
VOLCANOES
WHAT ARE THE BASIC FEATURES OF VOLCANO?
VENT - OPENING
CRATER - FILLED WITH WATER
CALDERA - FORMED WHEN A VOLCANO COLLAPSES
TYPES OF VOLCANOES
COMPOSITE,CINDER,SHIELD
DEFINE COMPOSITE VOLCANO
ALSO KNOWN AS STRATOVOLCANOES, MOST DANGEROUS TYPE OF VOLCANO
DEFINE CINDER VOLCANO
IT IS THE SMALLEST TYPES OF VOLCANOES
DEFINE SHIELD VOLCANO
ERUPTIONS ARE GENTLE AND NOT LIFE THREATHENING
