16
Q

is the peeling off of the outer layer rocks. Due to intense heating.

A

Exfoliation

17
Q

is the alternate freezing and melting of water in the joints of rocks.

A

Frost Action

18
Q

What are the four type of Chemical Weathering?

A
  1. ) Oxidation
  2. ) Hydration
  3. ) Solution
  4. ) Carbonation
19
Q

oxygen reacts on ferrous material found in rocks producing oxide.

A

Oxidation

20
Q

is the absorption of water. Volume will increase then it will lose its shape.

A

Hydration

21
Q

the minerals in rocks dissolved in water.

A

Solution

22
Q

formation of carbonates.

ex. Carbon Dioxide reacts on limestone then produces carbonic acid.

A

Carbonation

23
Q

What are the eight types of Biotic Waethering?

A
  1. ) plant roots
  2. ) Burrowing
  3. ) Human Being
  4. Erosion
  5. ) Lithification
  6. ) Metamorphic
  7. ) Aphanite
  8. ) Phanerite
24
Q

are penetrarting into the joints of rocks.

A

Plant Roots

25
Q

means digging

ex. ants, termites, rats, rabbits, and earthworms

A

Burrowing

26
Q

by doing activities like agriculture, construction of houses and roads, and quarry.

A

Human Being

27
Q

is the destruction made by nature forces. Transportation from one place to another by the means of water, wind, and ice.

A

Erosion

28
Q

is a process of porosity destruction through compaction and cementation.

A

Lithification

29
Q

are the result of extreme heat and pressure. Formed below the earth surface due to movements of plates. Also formed by collision of plates.

A

Metamorphic rocks

30
Q

is a fine-grained igneous rock having such compact texture that the constituent minerals cannot be detected with the naked eye.

A

Aphanite

31
Q

is an igneous rock whose microstructure is made up of crystals large enough to be distinguished with the unaided eye.

A

Phanerite
