Lesson 13.2

Question 1

Rocks respond to
stress by flowing,
bending or
breaking.

This constant
exposure causes
rock deformation
which will
eventually lead to
folding and
faulting.

Question 2

Types of Stress on Rocks

Answer 2

Confining stress
Directed stress

Question 3

takes place when a rock
or sediment is buried and acts uniformly in
all directions.

Answer 3

Confining stress

Question 4

only acts in one direction
and is most likely associated with tectonic
activities.

Answer 4

Directed stress

Question 5

Types of Directed Stress

Answer 5

Compression
Tension
Shear

Question 6

squeezing
stress

Answer 6

Compression

Question 7

pulling stress

Answer 7

Tension

Question 8

parallel but
opposite
directions

Answer 8

Shear

Question 9

The different types of stress on rocks can cause them to deform.

Question 10

The type of deformation that rocks can undergo also depend on the
composition of rock, or the type and intensity of stress.

Question 11

Types of Deformation

Answer 11

Elastic
Ductile
Brittle

Question 12

rock returns to
original shape

Answer 12

Elastic

Question 13

rock reshapes
without
breaking

Answer 13

Ductile

Question 14

causes
breakage

Answer 14

Brittle

Question 15

Some rocks fracture
because of stress.

Question 16

is a discernible
displacement where rocks
grind or slide past each
other.

Answer 16

fault

Question 17

a force exerted on an object, in this case, a rock.

Answer 17

Stress

Question 18

involves changes shape and/or size that can either
be permanent or temporary.

Answer 18

Rock deformation

Question 19

are series of wavelike ripples or bends,

Answer 19

Folds
