Answer 2

Exogenic Processes

Question 3

These are geological processes that occur beneath the surface of the earth

Answer 3

Endogenic Processes

Question 4

What are the different Exogenic processes?

Answer 4

A. Mass Wasting
B. Weathering
C. Erosion
D. Sedimentation

Question 5

Mass Wasting

Answer 5

It is the downslope movement of rock, soil and other debris due to the influence of gravity.

Question 6

Weathering

Answer 6

It is a process which is the breaking down of rocks physically or chemically

Question 7

Erosion

Answer 7

The process in which rocks and sediments are picked up and moved to another place by ice, water, wind and gravity.

Question 8

Sedimentation

Answer 8

The process in which a material is carried to the bottom of bodies of water and forms solid

Question 9

What are the seven classifications of Mass wasting?

Answer 9

1. Slump
2. Solifluction
3. Earthflow
4. Mudflow
5. Debris slide
6. Rock flow
7. Soil creep

Question 10

What are the two types of mass wasting processes?

Answer 10

1. Rapid mass wasting

2. Slow mass wasting

Question 11

What is slump?

Answer 11

Results in the sliding of coherent rock materials along a curved surface.

Question 12

What is Solifluction?

Answer 12

Is the slow downhill flow of soil

Question 13

What is Earthflow?

Answer 13

A downslope viscous flow of fine-grained materials that have been saturated with water and moves under the pull of gravity.

Question 14

What is Mudflow?

Answer 14

It that occurs when mud travels down a slope very quickly.

Question 15

Debris Slide

Answer 15

The type of slide which has a chaotic movement of rain of rocks, soil and debris that are mixed with water or ice.

Question 16

Rockflow

Answer 16

A type of mass wasting that occurs when pieces of rock break loose from a steep rock cliff.

Question 17

Soil creep

Answer 17

Is a slow gradual movement of soil downhill over time.

Question 18

What are the factors that affect mass wasting?

Answer 18

1. Water
2. Earthquake
3. Over-steepened slope
4. Vegetational removal

Question 19

Physical weathering

Answer 19

A type of weathering where rocks are physically broken into smaller units.

Question 20

Chemical weathering

Answer 20

The process of breaking down rocks through changes

Question 21

Factors that affect physical weathering

Answer 21

1. Ice wedging
2. Release of pressure
3. Growth of plants
4. Animals
5. Abrasion

Question 22

Factors that affect Chemical weathering

Answer 22

1. Water
2. Oxygen
3. Carbon Dioxide
4. Living Organisms
5. Acid rain

Question 23

What are the four types of Erosion

Answer 23

1. Erosion by water
2. Erosion by ice
3. Erosion by wind
4. Erosion by gravity

Question 24

Erosion by water

Answer 24

It changes the shape of coastlines

Question 25

Erosion by Ice

Answer 25

They erode the land

Question 26

Erosion by wind

Answer 26

carries dust, sand and volcanic ash from one place to another.

Question 27

Erosion by gravity

Answer 27

It pulls any loose bits down the slide of a hill or mountain

Question 28

What are the main types of Endogenic processes

Answer 28

1. Folding 2. Faulting 3. Volcanism 4. Metamorphism 5. Earthquake

Question 29

The process by which folds are formed due to the compression of forces

Answer 29

Folding

Question 30

What is faulting?

Answer 30

The fracturing and displacement of brittle rocks along a fault plane cause by tension or compression

Question 31

What are the types of Faulting

Answer 31

Normal fault Reverse fault Tear fault

Question 32

The forces within the earth that causes the ground to move

Answer 32

Endogenic forces
