Lesson 5: Rock Behavior Under Stress (Identification)

Question 1

It is the force applied to an object

Answer 1

Stress

Question 2

In Earth Science it is the force unit area that is placed on the rock. What is this?

Answer 2

Stress

Question 3

This means that the rock change its shape or size.

Answer 3

Deform

Question 4

What are the 2 types of stress

Answer 4

1. Confining Stress
2. Defferential Stress

Question 5

What are 3 types of differential stress?

Answer 5

1. Tensional Stress
2. Compressional Stress
3. Shear Stress

Question 6

What stress is caused for rocks to lengthen and break apart?

Answer 6

Tensional Stress

Question 7

What type of stress can be found in divergent plate boundaries?

Answer 7

Tensional Stress

Question 8

What type of stress that cause rocks to fold or fracture. This squeezes the rock together?

Answer 8

Compressional Stress

Question 9

Where compressional stress usually happen?

Answer 9

Convergent plate boundaries

Question 10

What type of stress where rocks past each other in opposite direction, this cause slippage and translation?

Answer 10

Shear Stress

Question 11

This type of stress usually happens in transform plate boundaries.

Answer 11

Shear Stress

Question 12

There are 3 stages of rock deformation and what are those?

Answer 12

1. Elastic Deformation
2. Ductile Deformation
3. Fracture

Question 13

What stage of deformation is when the rock return to its original shape when the stress is removed?

Answer 13

Elastic Deformation

Question 14

What stage of rock deformation is it when the rock didn’t go back to its original shape when the stress is removed?

Answer 14

Ductile Deformation

Question 15

It is the stage when the rock breaks.

Answer 15

Fracture

When the stress and strain goes up the the elastic region will show until the plastic region and then the rock will fracture.

Question 15

It is the stage when the rock breaks.

Answer 15

Fracture

When the stress and strain goes up the the elastic region will show until the plastic region and then the rock will fracture.

Question 16

What are the factors affecting the rock deformation?

Answer 16

1. Rock type
2. Temperature
3. Pressure condition
4. Time
5. Type of stress

Question 17

This refers when the rock experienced compressive stress and deformed plastically.

Answer 17

Folds

Question 18

This cause the bending or rocks.

Answer 18

Folds

Question 19

What are three types of folds?

Answer 19

1. Monoclines
2. Anticlines
3. Synclines

Question 20

This refer to the type of folds where there is a bending of rock layer wherein the oldest rock are at the bottom and the youngest are at the top?

Answer 20

Monoclines

Question 21

What type of folds that arches upward where the oldest rocks are found at the center while the youngest rocks are draped over them at the top of the structure.

Answer 21

Anticlines

Question 22

What structure us refer to when the upward folding of rocks form a circular structure?

Answer 22

Dome

Question 23

What type of folds that bends downward which rocks are curved down to the center?

Answer 23

Synclines

Question 24

What type of folds where the youngest rock are at the center and the older rocks are at the outside edges?

Answer 24

Synclines

Question 25

What called to the rock bend downeard in a circular structure ?

Answer 25

Basin

Question 26

It is a rock under ample stress that can crack or fracture?

Answer 26

Faults

Question 27

What called to the fracture because there is a block of rock left standing on either side of a fracture line?

Answer 27

Joint

Question 28

It is the rock that place on the top of the fault.

Answer 28

Footwall

Question 28

It is the rock that place on the top of the fault.

Answer 28

Footwall

Question 29

This can be found below the Earth.

Answer 29

Hanging wall

Question 30

Faults can be calssified into 3. What are those?

Answer 30

1. Normal Faults 2. Reverse Faults 3. Strike Slip Faults

Question 31

This refers to the type of fault that can be found usually in divergent boundaries?

Answer 31

Normal Faults

Question 32

This faults, in relationto the footwall, it develops as hanging wall derops down

Answer 32

Normal Faults

Question 33

This type of fault is commonly found in convergent boundaries

Answer 33

Reverse Fault

Question 34

This fault forms when a hanging wall moves up and this creates the world's highest mountain range

Answer 34

Reverse Fault

Question 35

Answer 35

Strike slip fault

Question 36

What type of faults formed when the walls move sideways?
