Lesson 1: WEATHERING

Question 1

This process includes degradation or breaking down of rocks into smaller segments known as sediments by the action of the following: water, ice, acids, salts, animals, gravity, and changing temperature.

Answer 1

WEATHERING

Question 2

is caused by the effects of changing temperature on rocks, causing the rock to break apart. This process is sometimes assisted by water.

Answer 2

PHYSICAL

Question 3

It occurs when rocks surface is frequently exposed to water, wind and gravity

Answer 3

Abrasion

Question 4

Occurs when water continually seeps into cracks, freezes and exapands

Answer 4

FREEZE-THAW

Question 5

Is a human made structure that is most vulnerable to weathering due to freezing and thawing cycle in mountainous region

Answer 5

CONCRETE HIGHWAYS

Question 6

It can happen as cracks develop parallel to the land surface as a consequence of the reduction in pressure during uplift erosion

Answer 6

EXFOLIATION

Question 7

Is caused by rainwater reacting with the mineral grains in rocks to form new minerals(clays) and soluble salts

Answer 7

Chemical

Question 8

Occurs when rocks are weakened by different biological agents like plants and animals

Answer 8

BIOLOGICAL

Question 9

Classication of biological weatherinh

Answer 9

A. Biological Weathering by Physical Means
B. biological Weathering by Chemical Compound

Question 10

The process of growth increase typically by the gradual accumulation of additional layers or Matter

Answer 10

ACCRETION

Question 11

Process of heat transfer by the bulk movement of molecule within fluids such as gases an fluids

Answer 11

CONVECTION

Question 12

The process of transmission of energy from one particle of the medium to another with the particles being in direct contact with each other

Answer 12

CONDUCTION

Question 13

(also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration) is the process by which an unstable atomic nucleus loses energy by radiation.

Answer 13

Radioactive decay

Question 14

Is a geological process that was formed, originated, and located below th surface of the earth.

Answer 14

ENDOGENIC PROCESS

Question 15

Molten rocks found beneath the surface of the earth

Answer 15

Magma

Question 16

Rocks undergo partial melting because minerals that compose them melt at different temperature

Answer 16

PARTIAL MELTING ( COMPONENTS OF MAGMA)

Question 17

Takes place within Earth when a body of rock is held at approximately the same temperature but the pressure is reduced

Answer 17

Decompression melting

Question 18

Happens if a rock is close to its melting point and some water or carbon dioxide is added to the rock

Answer 18

Flux melting

Question 19

is magma that moves up into volcano without erupting

Answer 19

Intrusion

Question 20

is an eruption of magmatic materials that causes land formation on the earth surface

Answer 20

Extrusion

Question 21

is a molten rock found on the surface of the Earth

Answer 21

LAVA

Question 22

Are created and formed when energy generated by inductive current flowing from Earth’s core

Answer 22

Volcanoes

Question 23

The higher the pressure, the higher the melting points

Answer 23

Rocks

Question 24

Contains interlocking and large crystal of minerals compared to minerals found in igneous rocks

Answer 24

Igneous Rocks

Question 25

Contains a mixture of minerals, organic matter, and fragments of other rocks or minerals

Answer 25

Sedimentary rocks

Question 26

Contain a variety of minerals, depending on the original rock that underwent metamorphism and the condition it experienced

Answer 26

Metamorphic rocks

Question 27

the process where a pre-existing rock transform into another form of rock

Answer 27

Metamorphism

Question 28

Factorz involved in the process of metamorphism

Answer 28

1. Temperature 2. Pressure 3. Hydrothermal fluids

Question 29

In which the alternation process is caused by fluids passig through the rock and catalyze chemical reactions

Answer 29

Metamsomatism

Question 30

a metamorphic transformation of ferromagnesian minerals, such as olivine and pyroxene, in mafic and ultramafic rock tro produce serpentinute mineral

Answer 30

Serpentization process

Question 31

The confining and directing pressure

Answer 31

Regional Metamorphism

Question 32

Results from heat from nearby magma

Answer 32

Contact Metamorphism

Question 33

When the heat and shock waves from meteor or asteroid impact transform rocks immediately arround the impact site

Answer 33

Shock Metamorphism

Question 34

Occurs at lower temperature and pressure which transform sedimentary rock

Answer 34

Burial Metamorphism

Question 35

Metamorphic rocks formed trough these types of metamorphism contains bits of microscopic diamonds

Answer 35

High pressure metamorphism
