The process in which water,
wind, ice, and heat break down
rock is called

What is Weathering ?
3
1
This process transports rock
sediment from one place to another
4
2
What is Erosion ?
5
2
Scientists classify rocks by …..
6
3
What are composition &
7

texture
How is magma is formed
8
4
1. Temperature
2. Pressure
3. Change in the composition
can cause magma to form
9
4
How is clastic sedimentary
rock different from chemical
sedimentary rock
10
5
What is
Clastic sedimentary rock is formed
from rock fragments that are
cemented together by a mineral.
Chemical sedimentary rock is made
of crystallized minerals that were
previously dissolved.
11

What kind of rock is formed
when magma intrudes into
other rock
12
1
What is Intrusive
13

igneous rock ?
What kind of rock is formed
from lava that cools on the
Earth’s surface
Double points

What is
Extrusive igneous rock

What kind of sedimentary rock is
made from fossils

What is Organic ?

Which process forms sediment

What is weathering

Describe how contact
metamorphism is different
from regional metamorphism
20
5
Contact metamorphism occurs
when magma comes into direct
contact with rock.
Regional metamorphism occurs
when large pieces of the Earth’s
crust collide with each other.
21
5
What is the process called in
which sedimentary rocks are
arranged in layers?
22

What is stratification ?

How did humans use rocks in the
past

What are to make tools, buildings

What are the 3 main categories of
sedimentary rock

Partially decomposed plant

Describe the texture of
nonfoliated rock.
30
5
Nonfoliated rock has mineral
grains that are not aligned.

What do bends or folds in rocks
show
32
1
What is the deformation of a
rock by pressure
33

What occurs when temperature
and pressure inside the
Earth’s crust change
Double points

What is metamorphism
35

What forces change a sedimentary
rock into a metamorphic rock
Double points
36
3
What are heat

and pressure ?
What do all igneous rock begin as
38
4
What is magma
39
4
What is stratification,
and why is it important
to Earth scientists
40
5
Stratification is the layering of rock.
It is important because it records
many events in Earth’s history (as
well as erosion and deposition
Rates)

What do you call rocks made
from animal or plant remains
42
1
What is organic
sedimentary rock
43
1
What do you call the chemical
makeup of a rock
44
2
What is composition
45
2
What is a solid mixture of crystals
or one or more minerals
46
3
What is a Rock
47
3
What does the composition of a
metamorphic rock tell you
about the rock’s origin and
formation
48
4
Different metamorphic minerals indicate:
INDEX MINERALS -temperature and
pressure conditions that existed when
rock formed
49
4
Describe the rock cycle
50
5
Some things you might say:
The rock cycle is a fundamental concept in geology
Describes the transitions through geologic for 3 main
rock types: sedimentary, metamorphic, igneous.
Changes take place by different processes such as:
weathering, erosion, deposition, compaction,
cementation, heating, cooling, pressure, solidification,
& uplifting
