Biotic Weathering

Question 13

What are the three types of Weathering?

Answer 13

1. ) Physical
2. ) Chemical
3. ) Biotic

Question 14

what are the three types of Physical Weathering?

Answer 14

1. ) Block disintegration
2. ) Exfoliation
3. ) Frost Action

Question 15

is the successive heating and cooling of rocks. If hot it’ll expand and when it’s cold, it’ll shrink.

Answer 15

Block disintegration

Question 16

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

Answer 16

Exfoliation

Question 17

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

Answer 17

Frost Action

Question 18

What are the four type of Chemical Weathering?

Answer 18

1. ) Oxidation
2. ) Hydration
3. ) Solution
4. ) Carbonation

Question 19

oxygen reacts on ferrous material found in rocks producing oxide.

Answer 19

Oxidation

Question 20

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

Answer 20

Hydration

Question 21

the minerals in rocks dissolved in water.

Answer 21

Solution

Question 22

formation of carbonates.

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

Answer 22

Carbonation

2. ) Burrowing
3. ) Human Being
4. Erosion
5. ) Lithification
6. ) Metamorphic
7. ) Aphanite
8. ) Phanerite

Question 24

are penetrarting into the joints of rocks.

Answer 24

Plant Roots

Question 25

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

Answer 25

Burrowing

Question 26

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

Answer 26

Human Being

Question 27

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

Answer 27

Erosion

Question 28

is a process of porosity destruction through compaction and cementation.

Answer 28

Lithification

Question 29

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

Answer 29

Metamorphic rocks

Question 30

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

Answer 30

Aphanite

Question 31

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

Answer 31

Phanerite
