4. •IGNEOUS ROCKS ARE FORMED FROM THE
COOLING AND SOLIDIFICATION OF MOLTEN
ROCK MATERIAL. THERE ARE TWO BASIC
TYPES.

5. •LATIN: IGNEUS “FIERY” OR “ON FIRE”

6. •1. BELOW THE SURFACE
•2. ON THE SURFACE
•3. ON THE SURFACE PART 2

7. BELOW THE SURFACE (INTRUSIVE)
•FROM SLOWLY COOLING MAGMA
•INTRUSIVE IGNEOUS ROCKS CRYSTALLIZE BELOW
EARTH'S SURFACE, AND THE SLOW COOLING THAT
OCCURS THERE ALLOWS LARGE CRYSTALS TO FORM THAT
ARE VISIBLE TO THE NAKED EYE.

8. •DIORITE IS A
COARSE-
GRAINED,
INTRUSIVE
IGNEOUS ROCK
THAT CONTAINS A
MIXTURE
OF FELDSPAR,
PYROXENE, HORN
BLENDE, AND
SOMETIMES QUA
RTZ.

9. • PEGMATITE IS A LIGHT-
COLORED, EXTREMELY
COARSE-GRAINED
INTRUSIVE IGNEOUS
ROCK. IT FORMS NEAR
THE MARGINS OF A
MAGMA CHAMBER
DURING THE FINAL
PHASES OF MAGMA
CHAMBER
CRYSTALLIZATION. IT
OFTEN CONTAINS RARE
MINERALS THAT ARE
NOT FOUND IN OTHER
PARTS OF THE MAGMA
CHAMBER.

10. •GRANITE IS A
COARSE-
GRAINED, LIGHT-
COLORED,
INTRUSIVE
IGNEOUS ROCK
THAT CONTAINS
MAINLY QUARTZ,
FELDSPAR, AND
MICA MINERALS.

11. •GABBRO IS A
COARSE-
GRAINED, DARK-
COLORED,
INTRUSIVE
IGNEOUS ROCK
THAT CONTAINS
FELDSPAR,
PYROXENE, AND
SOMETIMES OLIVI
NE.

12. •PERIDOTITE IS A
COARSE-GRAINED
INTRUSIVE IGNEOUS
ROCK THAT IS
COMPOSED ALMOST
ENTIRELY OF OLIVINE.
IT MAY CONTAIN
SMALL AMOUNTS OF
AMPHIBOLE,
FELDSPAR, QUARTZ,
OR PYROXENE.

13. ON THE SURFACE (EXTRUSIVE)
•FROM RAPIDLY COOLING LAVA
•EXTRUSIVE IGNEOUS ROCKS ERUPT ONTO THE SURFACE,
WHERE THEY COOL QUICKLY TO FORM SMALL CRYSTALS.
SOME COOL SO QUICKLY THAT THEY FORM AN
AMORPHOUS GLASS.

14. •ANDESITE IS A
FINE-GRAINED,
EXTRUSIVE
IGNEOUS ROCK
COMPOSED
MAINLY OF
PLAGIOCLASE
WITH OTHER
MINERALS SUCH
AS HORNBLENDE,
PYROXENE,
AND BIOTITE.

15. •BASALT IS A FINE-
GRAINED, DARK-
COLORED
EXTRUSIVE
IGNEOUS ROCK
COMPOSED
MAINLY
OF PLAGIOCLASE
AND PYROXENE.

16. •RHYOLITE IS A
LIGHT-COLORED,
FINE-GRAINED,
EXTRUSIVE
IGNEOUS ROCK
THAT TYPICALLY
CONTAINS QUART
Z AND FELDSPAR
MINERALS

17. • SCORIA IS A DARK-
COLORED, VESICULAR,
EXTRUSIVE IGNEOUS
ROCK. THE VESICLES ARE
A RESULT OF TRAPPED
GAS WITHIN THE MELT AT
THE TIME OF
SOLIDIFICATION. IT
OFTEN FORMS AS A
FROTHY CRUST ON THE
TOP OF A LAVA FLOW OR
AS MATERIAL EJECTED
FROM A VOLCANIC VENT
AND SOLIDIFYING WHILE
AIRBORNE.

18. •PUMICE IS A LIGHT-
COLORED VESICULAR
IGNEOUS ROCK. IT
FORMS THROUGH
VERY RAPID
SOLIDIFICATION OF A
MELT. THE
VESICULAR TEXTURE
IS A RESULT OF GAS
TRAPPED IN THE
MELT AT THE TIME OF
SOLIDIFICATION

19. ON THE SURFACE (PYROCLASTIC ROCKS)
•FROM THE CONSOLIDATION OF PARTICLE ERUPTED
BY EXPLOSIVE VOLCANIC ACTIVITY

20. •WELDED TUFF IS A
ROCK THAT IS
COMPOSED OF
MATERIALS THAT
WERE EJECTED FROM
A VOLCANO, FELL TO
EARTH, AND THEN
LITHIFIED INTO A
ROCK. IT IS USUALLY
COMPOSED MAINLY
OF VOLCANIC
ASH AND
SOMETIMES
CONTAINS LARGER
SIZE PARTICLES
SUCH AS CINDERS.

21. •FIRE OPAL IS
SOMETIMES FOUND
FILLING CAVITIES
IN RHYOLITE. LONG
AFTER THE RHYOLITE
HAS COOLED, SILICA-
RICH GROUND
WATER MOVES
THROUGH THE ROCK,
SOMETIMES
DEPOSITING GEMS
LIKE OPAL, RED
BERYL, TOPAZ,
JASPER, OR AGATE IN
THE CAVITIES OF THE
ROCK.

22. •OBSIDIAN IS A
DARK-COLORED
VOLCANIC GLASS
THAT FORMS
FROM THE VERY
RAPID COOLING
OF MOLTEN ROCK
MATERIAL. IT
COOLS SO
RAPIDLY THAT
CRYSTALS DO
NOT FORM.
