30
Q

Rain water adds weight and act as lubricant to weathered material

A

31
Q

It is the reponse of oxygen with minerals

A

Oxidation

32
Q

If the iron oxidizes, the mineral in rocks _________.

A

decomposes

33
Q

Rusting is an example of this chemical reaction

A

Oxidation

34
Q

Rock forming minerals like amphibole, pyroxene, and feldspar react with water and form different kinds of clay minerals

A

Hydrolysis

35
Q

It occurs in specific minerals which are dissolved in water

A

Dissolution

36
Q

The breaking down of rocks is caused by impact and friction

A

Abrasion

37
Q

Animals exacavate into the ground to create a space for habitation

A

Burrowing Animals

38
Q

Activities such as digging, quarrying, denuding forests and cultivating land contribute to physical weathering.

A

Human Activities

39
Q

The roots grow causing penetration into the crack, expand, and in the long run, break the rock.

A

Organic Activity

40
Q

Rocks expand and are fractured when expose to high temperature and low temperature

A

Temperature

41
Q

Rocks have fracture in its surface and when water accumulates in the crack and at that point freezes, the ice expands and break the rocks apart

A

Frost Wedging

42
Q

The rock expands, cools and became brittled and fractured due to tectonic forces

A

Pressure

43
Q

What are 4 factors that triggers mass wasting?

A

-Over-steepened slope
-Earthquake
-Water
-Vegetation Removal

44

steep slopes

45
Q

Slow movements are found on _______

A

gentle slopes

46
Q

the slow downhill flow of soil

A

Solifluction
