What is the rock cycle?
-Processes rocks continually go through when
they change from one form to another.

and how they change from one form to another.

6
What are igneous rocks?
-rocks formed from the cooling of magma or
lava, above or below the Earth’s surface.
7.
Name the two basic types of igneous rocks, how they are formed, and
give one example of each type?
TYPE
HOW FORMED
EXAMPLE
a.
Intrusive
Magma cools
underground
Granite
b. Extrusive
Lava cools on
the surface
Pumice
8. The process in which sediment is removed from its source and transported is
called Erosion
9.
What are sedimentary rocks?
-Rocks that form on the surface of the
Earth by rock particles being cemented
together
10.
Name the three major types of sedimentary rocks, how they are formed,
and give one example of each type?
TYPE
HOW FORMED
EXAMPLE
a.
Clastic
b. organic
c. Chemical
broken pieces of
Conglomerate
rocks or minerals being
Sandstone
glued together
remains of once living Limestone &
organisms
Coal
minerals dissolving
by weathering separate
and crystallize
Halite
(Rock Salt)
Rocks formed usually
underground from intense heat and pressure
11.
What are metamorphic rocks?
12.
Name the two basic groups of metamorphic rocks, how they are formed,
and give one example of each type?
TYPE
HOW FORMED
EXAMPLE
a. Foliated
Heat and Pressure
b. Non-foliated
13.
heat and pressure
Slate/ Gneiss
Marble
What property is used to classify metamorphic rocks?
-whether they are banded (layered) or not
14.
What is weathering?
- Water, wind, ice, and gravity breaking apart
rocks
15. If a rock is buried deep inside the Earth, which geological processes
cannot change the rock? Explain your answer.
-weathering: this process happens on Earth’s
surface
