Mid-Chapter 2 Review
Lesson 2.1: Minerals and Rocks
&
Lesson 2.2: Rocks and Weathering
This type of rock forms when molten
material cools.
What is igneous rock?
These are the five characteristics of a
mineral.
What are:
1. Naturally occurring
2. Inorganic
3. Solid
4. Crystal shape
5. Definite chemical
composition
This process slowly changes rocks
from one kind to another.
What is the rock
cycle?
Animals that burrow in the ground
help contribute to this type of
weathering.
What is mechanical
weathering?
When water freezes in a rock it
expands causing the crack to widen.
What is ice wedging?
This picture is an example of what
type of mining?
What is an
open-pit mine?
This type of rock forms through the
process of compaction and
cementation.
What is sedimentary
rock?
Rain combined with pollutants help to
form this type of rapid chemical
weathering.
What is acid rain?
This mineral characteristic is made up
of particles that line up in a pattern
that repeats over and over again.
What is crystal shape?
Rocks are considered to be this
because they take millions of years to
be replaced.
What is a nonrenewable resource?
Rocks that are made up of tiny,
connected air spaces are considered
this.
What is permeable?
To remove ore deposits that occur in
veins, miners build this type of mine.
What is a shaft mine.
Which of the following is NOT one of
the possible stages in the rock cycle?
1.
2.
3.
4.
Erosion
Volcanic activity
Melting
Smelting
What is smelting?
This type of weathering occurs more
rapidly in hot, wet climates.
What is chemical weathering?
The movement of rock particles by
ice, wind, water, or gravity is known as
this.
What is erosion?
This type of igneous rock is
commonly used for building materials.
What is granite?
Intense heat and pressure can change
the minerals in rock into this type of
rock.
What is metamorphic
rock?
Floors, kitchen counters, walls of
buildings, roofing, cement and steel
are all examples of this.
What are possible uses of
rocks?
This mineral characteristic did not
form from materials that were once
living.
What is inorganic?
The type of mining where soil is
scraped away to expose ore.
What is a strip
mine?
The grinding away of rock by rock
particles carried by water, wind, or
gravity is known as this.
What is abrasion?
The End.
How did you do?
