THE ROCK CYCLE Flashcards
=process involving
the transformation and generation of
igneous, sedimentary, and
metamorphic rocks.
=Rocks are constantly being
transformed, generated, and destroyed in a process called
ROCK CYCLE
outermost layer of our planet composed of
the _ and the _
crust and the upper mantle
composed of rock and minerals
EARTH
extends to a depth of about 100 kilometers down the
surface containing different rocks and minerals
from both the continents and the oceans.
LITHOSPHERE
naturally-occurring
aggregate or combination of
minerals and mineraloids, such as
fossils and glass.
ROCKS
are the natural building
blocks of Earth’s lithosphere.
ROCKS
EXAMPLES OF IGNEOUS ROCKS:
GRANITE, DIORITE, CYANITE, BASALT, ANDESITE
_ rocks are formed through the cooling of magma or lava
IGNEOUS ROCKS
IGNEOUS IS BASED ON LATIN WORD WHICH MEANS
IGNIS
IGNIS MEANS
FIRE
Magma or lava may be solidified in
one of three ways:
=Below the surface:from a slow-cooling
magma;
=On the surface:from fast-cooling lava
=On the surface: the consolidation of
particles erupted by explosive volcanic
activity;
_ rocks accumulate on earth’s surface
SEDIMENTARY ROCKS
SEDIMENTARY ROCKS IN A PROCESS CALLED_
DESPOSITION
THE PROCESS BY WHICH THESE UNCONSOLIDATED MATERIAL BECOMES INTO ROCK IS CALLED _
Lithification
EXAMPLES OF SEDIMENTARY ROCKS:
CLAY, LIMESTONE, SANDSTONE, CONGLOMERATE, BAUXITE
