Question 12

2 FORMATION OF IGNEOUS ROCKS AND GIVE EXAMPLES

Answer 12

EXTRUSIVE ROCKS (EXAMPLE : OBSIDIAN, BASALT)
ITNRUSIVE ROCKS ( EXAMPLE : GRANITE, GABRO)

Question 13

FORMED ABOVE THE GROUND WHEN LAVA FLOWS OR EXPLODES, COOLS QUICKLY

Answer 13

EXTRUSIVE ROCKS

Question 14

FORMED UNDERGROUND FROM MAGMA, COOLS SLOWLY

Answer 14

INTRUSIVE ROCKS

Question 15

WHAT IS THE TEXTURE OF IGNEOUS ROCK

Answer 15

DEPENDS ON THE SIZE AND SHAPE OF THE CRYSTALS WHEN THE ROCK FORMS. THIS IS DUE TO THE COOLING RATE OF THE ROCKS.

Answer 18

GLASSY, APHANITIC, PHANERITIC, PROPHYRITIC

Question 19

IGNEOUS ROCKS HAVE NO CRYSTAL STRUCTURE

Answer 19

GLASSY

Question 20

IT HAS CRYSTALS BUT NOT VISIBLE

Answer 20

PROPHYRITIC

Question 23

(TRUE OR FALSE)
HIGH IN SILICA USUALLY APEARS LIGHT IN COLOR

Answer 23

TRUE

Question 24

(TRUE OR FALSE)
LOW AMOUNT OF SILICA USUALLY USUALLY PRODUCES DARK COLORED ROCKS

Answer 24

TRUE

Question 25

WHAT ARE THE COMMON TYPES OF IGNEOUS ROCKS?

Answer 25

-BASALT -GRANITE -DIORITE -GABBRO

Question 26

MADE WHEN SEDIMENTS ARE PRESSED TOGETHER OVERTIME AND BECOME A ROCK.

Answer 26

SEDIMENTARY ROCKS

Question 27

FORMATION OF SEDIMENTARY ROCKS

Answer 27

EROSION, DEPOSITION, COMPACTION, AND CEMENTATION

Question 28

DEFINE EROSION

Answer 28

WEARING AWAY OF ROCK, DIRT, SOIL, PARTICLES ETC. DUE TO WIND

Question 29

DEFINE DEPOSITION

Answer 29

SEDIMENTS FROM EROSION ARE LEFT OR DEPOSITED IN A DIFFERENT PLACE

Question 30

DEFINE COMPACTION

Answer 30

BUILD UP OVERTIME AND PRESS DOWN ON THE LAYERS BELOW

Question 31

DEFINE CEMENTATION

Answer 31

ARE DISSOLVED IN WATER START TO CRYSTALLIZED. THESE CRYSTALLIZED MINERALS "GLUE" THE SOLIDS OR GRAINS TOGETHER

Question 32

CLASSIFICATION OF SEDIMENTARY ROCKS

Answer 32

-CLASTIC -ORGANIC -CHEMICAL

Question 33

DEFINE CLASTIC

Answer 33

FORMED BY SEDIMENTS THAT WERE ERODED LONG TIME AGO

Question 34

DEFINE ORGANICS

Answer 34

MADE FROM THE REMAINS OF PLANTS AND ANIMALS

Question 35

DEFINE CHEMICAL

Answer 35

DISSOLVED CHEMICAL SOLUTION THAT CRYSTALLIZED

Question 36

COMMON TYPES OF SEDIMENTARY ROCKS

Answer 36

-LIMESTONE -GYPSUM -SANDSTONE -SHALE

Question 37

WHAT IS THE TEXTURE OF SEDIMENTARY ROCKS?

Answer 37

SMOOTH AND LIGHT IN COLOR

Question 38

DEFINE METAMORPHIC ROCKS

Answer 38

IT IS MADE UP OF OTHER ROCKS

Question 39

(TRUE OR FALSE) HEAT AND PRESSURE HELP CHANGE AN IGNEOUS OR SEDIMENTARY ROCK INTO A NEW KIND OF ROCK

Answer 39

TRUE

Question 40

(TRUE OR FALSE) METAMORPHIC ROCK HAS NO SPECIFIC COLOR

Answer 40

TRUE

Question 41

WHAT ARE THE 2 CLASSIFICATION OF METAMORPHIC ROCK?

Answer 41

FAILED METAMORPHIC ROCK NON-FAILED METAMORPHIC ROCK

Question 42

DEFINE FAILED METAMORPHIC ROCK

Answer 42

GRAINS ARE ARRANGED IN PARALLEL LAYERS OR BANDS

Question 43

DEFINE NON-FAILED METAMORPHIC ROCK

Answer 43

GRAINS ARE RANDOM. THEY DO NOT SPLIT INTO LAYERS.

Question 44

(TRUE OR FALSE) SEDIMENTARY ROCKS ORIGINALLY START OUT AS DIFFERENT TYPES OF ROCKS. BECAUSE OF PRESSURE WITHIN THE EARTH, THEY MELT AND CHANGE.

Answer 44

FALSE, ITS METAMORPHIC ROCK

Question 45

EXPLAIN THE ROCK CYCLE

Answer 45

THE EARTH RECYCLES. IGNEOUS, SEDIMENTARY AND METAMORPHIC ROCKS ARE CONSTANTLY CHANGING FROM NEW ROCKS. OLD ROCKS IS ERODED AND DEPOSITED SOMEWHERE ELSE TO BECOME SEDIMENTARY ROCKS. TECTONIC PLATE SUBDUCT INTO THE MANTLE TO MELT AND FORM IGNEOUS ROCK, INTRUSIVE IGNEOUS ROCK AND SEDIMENTARY ROCK ARE BURIED DEEP IN THE EARTH AND ARE SUBJECTED TO HIGH TEMPERATURE AND PRESSURE TO BECOME METAMORPHIC ROCK.
