Rock Behavior Under Stress

Question 1

Naturally occurring substance

Answer 1

Rock

Question 2

A process wherein heat and pressure change rocks physical and chemical make up.

Answer 2

Metamorphism

Question 3

The physical change that may occur during metamorphism.

Answer 3

Folistion

Question 4

Identify two main types of metamorphism.

Answer 4

Contact metamorphism
Regional metamorphism

Question 5

It is a type of metamorphism where contact rocks and changes it by extreme heat.

Answer 5

Contact metamorphism

Question 6

It is a type of metamorphism when great masses of rock are exposed to pressure.

Answer 6

Regional metamorphism

Question 7

The force per unit that is placed on rock.

Answer 7

Stress

Question 8

Enumerate 3 types of stress.

Answer 8

Tensional stress, Compressional stress, and shear stress.

Question 9

Type type of stress that causes rocks to be pulled apart. It can be found at the divergent plate boundaries.

Answer 9

Tensional stress

Question 10

Type of stress that causes rocks to fold or fracture it squeezes rocks together.

It is a common type of stress and convergent plate boundaries.

Answer 10

Compressional stress
Compression

Question 11

Type of stress that happens when forces light pass each other in opposite direction. It can be result to slippage and translation. Common stress found in transform plate boundaries

Answer 11

Shear stress

Question 12

Enumerate two types of geologic structure.

Answer 12

Folds
Faults

Question 13

It is formed when rocks experience compressive stress and deformed physically.

Answer 13

Folds

Question 14

Enumerate three types of folds

Answer 14

Monocline
Anticline
Syncline

Question 15

Simple bend in the rock layers where the oldest rocks are at the bottom and the youngest are at the top.

Answer 15

Monocline

Question 16

It is a type of folds that arches upward where the oldest rocks are found at the center of anticline. The youngest the rocks are covered over them at the top of the structure

Answer 16

Anticline

Question 17

It is a type of fold that bends downward which rocks are curved down to a center.

Answer 17

Syncline

Question 18

It is the geologic structure which rocks under ample stress crack or fracture. The fracture is called a joint because there is a block of rock left standing on either side of a fracture line. Foot wall is the rock that plays on top of the fault while hanging wall is below the fault.

Answer 18

Faults

Question 19

Enumerate three types of faults.

Answer 19

Normal faults
Reverse faults
Strike slip faults

Question 20

It is a type of faults that is most common at divergent boundaries. It develops as a hanging wall drops down. Example: East African Rift

Answer 20

Normal faults

Question 21

A type of fault that is common at divergent boundaries. Forms when the hanging wall moves up. Create the highest mountain ranges. Example: Himalayas mountain and Rocky mountain

Answer 21

Reverse faults

Question 22

A type of fault that is formed when walls move sideways. Either right lateral or left lateral. Common on transform plate boundaries. Example: San Andres Fault

Answer 22

Strike slip Faults
