Answer 1

EXOGENIC PROCESSES

Question 2

TYPES OF EXOGENIC PROCESSES

Answer 2

(WEATHERING, EROSION, MASS WASTING AND SEDIMENTATION)

Question 3

happens when rock is physically broken into smaller pieces.

Answer 3

physical weathering

Question 4

FACTORS THAT AFFECT PHYSICAL WEATHERING

Answer 4

Ice wedging
Release of pressure
Growth of plants
Animals
Abrasion

Question 5

H2O seeps in rock, expands, crack rocks into smaller pieces.

Answer 5

ice wedging

Question 6

Surface rock erodes, rock flakes like onion layers.

Answer 6

release of pressure

Question 7

Roots grow into cracks and push rocks apart.

Answer 7

growth of plants

Question 8

Burrow and push apart rock.

Answer 8

animals

Question 9

Sand and rock carried by wind, water, ice wears away surface rock when rocks collide. Most common in windy areas

Answer 9

abrasion

Question 10

is the process of breaking down rock through chemical changes.

Answer 10

chemical weathering

Question 11

FACTORS THAT AFFECT CHEMICAL WEATHERING

Answer 11

water
oxygen
carbon dioxide
living organisms
acid rain

Question 12

dissolves rock chemically.

Answer 12

water

Question 13

Rocks that has iron in it mixes with oxygen and rusts.

Answer 13

oxygen

Question 14

CO2 dissolves in rainwater and weathers marble and limestone.

Answer 14

carbon dioxide

Question 15

Acids from plants and roots chemically weather rock.

Answer 15

living organisms

Question 16

Air pollution reacts with clouds and falls on rock as _____

Answer 16

Acid rain

Question 17

Agents of Erosion

Answer 17

water, wind, ice and gravity

Question 18

changes the shape of coastlines. Waves constantly crash against shores. They pound rocks into pebbles and reduce pebbles to sand. Water sometimes takes sand away from beaches. This moves the coastline farther inland.

Answer 18

erosion by water

Question 19

carries dust, sand, and volcanic ash from one place to another. _____can sometimes blow sand into towering dunes.

Answer 19

erosion by wind

Question 20

can erode the land. In frigid areas and on some mountaintops, glaciers move slowly downhill and across the land. As they move, they pick up everything in their path, from tiny grains of sand to huge boulders.

Answer 20

erosion by ice

Question 21

pulls any loose bits down the side of a hill or mountain. _____Erosion is better known as Mass Movement.

Answer 21

erosion by gravity

Question 22

When weathered rock remains in place and remains in its pure state.

Answer 22

rigolith

Question 23

When weathered material is removed from the site of weathering

Answer 23

sediment

Question 24

It is the main agent of erosion. PEOPLE ~> Nowadays, people became one of the causes of erosion.

Answer 24

moving water

Question 25

Weathered rock material will be removed from its original site and transported away by a natural agent.

Answer 25

WEATHERING AND EROSION

Question 26

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

Answer 26

sedimentation

Question 27

is the movement of rock, soil and regolith downward due to action of gravity

Answer 27

mass wasting

Question 28

is a type of mass wasting that results in the sliding of coherent rock materials along a curved surface.

Answer 28

slump

Question 29

is the slow downhill flow of soil.

Answer 29

solifluction

Question 30

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

Answer 30

earthflow

Question 31

occurs when mud travels down a slope very quickly.

Answer 31

mudflow

Question 32

is a type of slide characterized by the chaotic movement of rocks, soil, and debris mixed with water and/or ice.

Answer 32

debris slide

Question 33

is a moving mass of loose mud, sand, soil, rock, water and air that travels down a slope under the influence of gravity.

Answer 33

debris flow

Question 34

occurs when pieces of rock break loose from a steep rock face or cliff.

Answer 34

rock flow

Question 35

is a slow, gradual movement of soil or regolith downhill over time.

Answer 35

soil creep

Question 36

rubble, trash, random material like large pieces of wood metal or plastic

Answer 36

debris

Question 37

river of flowing mid

Answer 37

slurry

Question 38

an incline like slide or ramp

Answer 38

slope

Question 39

land that is close to a coast or near water or sea levels

Answer 39

low lying area
