A

disaggregation

26
Q

combining is

A

aggregation

27
Q

those rock particles get carried away by wind, water, ice and gravity

A

Erosion

28
Q

agents of erosion

A

• Water
• Wind
• Ice
• Gravity

29
Q

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

A

erosion by water

30
Q

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

A

Erosion by wind

31
Q

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.

A

Erosion by ice

32
Q

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

A

Gravity Erosion

33
Q

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

A

REGOLITH

34
Q

When weathered material is removed from the site of weathering

A

SEDIMENT

35
Q

It is the main agent of erosion

A

MOVING WATER

36
Q

Nowadays, people became one of the causes of erosion.

A

PEOPLE

37
Q

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

A

WEATHERING AND EROSION

38
Q

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

A

debris

39
Q

river of flowing mud

A

slurry

40
Q

an incline,like a slide or ramp

A

slope

41
Q

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

A

low-lying area

42
Q

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

A

SEDIMENTATION

43
Q

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

A

Mass wasting

44
Q

triggered by the following factors:

A

OVER-STEEPENED
SLOPE

WATER
EARTHQUAKE
VEGETATION REMOVAL

45
Q

Rapid movements are
commonly found in steep
slopes while slow
movements are found on
gentle slopes.

A

OVER-STEEPENED
SLOPE

46
Q

adds weight
and acts as a lubricant to
weathered material.

A

WATER

47
Q

It is a vibration and also a
factor that triggers mass
wasting.

A

EARTHQUAKE

48
Q

The lack of vegetation
cover to hold the loose
particles.

A

VEGETATION
REMOVAL

49
Q

These are naturally occurring inorganic solids with crystalline structure, homogenous solid with chemical composition which may be fixed or vary within certain limits.

A

minerals

50
Q

rock forming minerals

53
Q

54
Q

minerals occur in nature

A

naturally occurring

55
Q

minerals have never been alive. not a by product of any living things

A

inorganic

56
Q
  • a mineral is made up of specific chemicals unique to that mineral.
A

DEFINITE CHEMICAL COMPOSITION

57
Q
  • neither a liquid nor a gas.
A
