Earth Sci For Babaaa

Front 1

It is the on-site breakdown or dissolving of rocks and minerals on the surface of the Earth

Back 1

Weathering

Front 2

It can be brought about by many agents such as water, ice, acids, salts, plants, animals, and changes in temperature.

Weathering

Front 3

Can be CHEMICAL or MECHANICAL

Back 3

Weathering

Front 4

It is the physical breakdown of rock into unconnected grains or chunks without changing its composition.

Front 9

What type of mechanical weathering is this?

Back 9

Salt wedging

Front 10

What type of mechanical weathering is this?

Back 10

Frost wedging

Front 11

It occurs when there are chemical changes in at least some of the composition of the rock.

Back 11

Chemical weathering

Front 12

In ________ rocks and minerals reacts to acids, oxygen, carbon and water.

Back 12

Chemical weathering

Front 13

Give 4 examples of chemical weathering

Back 13

Dissolution

Carbonation

Hydration

Oxidation

Hydrolysis

Front 14

It is a surface or near-surface process that is not influenced by high temperature or pressure.

What reaction that causes the rocks to weather?

Back 14

Chemical reaction

Front 15

In ________ water breaks down mineral grains into the elements that make them up

Back 15

Dissolution

Front 16

It happens in certain minerals which are dissolved in water – pure water and acidic water- especially when it rains.

Back 16

Dissolution/ Carbonation

Front 17

Explain the process of dissolution/ carbonation and give one example.

Back 17

As rain goes through the air and into the ground, it grabs carbon dioxide, creating carbonic acid. This weak acid reacts with the calcium carbonate in stones when it seeps into the cracks

Example: limestone

Front 18

________ is a type of chemical weathering where water reacts chemically with the rock, modifying its chemical structure. Water is absorbed into the crystal structure of the mineral, causing it to expand.

Back 18

Hydration

Front 19

True or fase

Oxidation creates different types of rocks

Back 19

False - hydration

Front 20

It is the reaction of oxygen with minerals in the rock.

Back 20

Oxidation

Front 21

In _________ oxygen reacts with the original material to create new material.

Back 21

Oxidation

Front 22

True or false

Hydrolysis is characterized by red, orange, and yellow stains that look like rust

Back 22

False - oxidation

Front 23

What is the most common example of hydrolysis

Back 23

Feldspar

Front 24

Where can u find the feldspar?

Back 24

Granite changing to clay

Front 25

In __________ elements in water (hydrogen and oxygen) replace elements in the original material, creating a new substance.

Back 25

Hydrolysis

Front 26

Give the three factors that affects weathering

Back 26

Climate

Hardness

Surface area

Front 27

It is the separation and removal of weathered rocks and soil due to gravity or transporting agents like wind, ice or water.

Back 27

Erosion

Front 28

It commonly occurs in flat,bare areas or dry, sandy, and loose soil

Back 28

Wind erosion

Front 29

It detaches soil particles and transports them by wind

Back 29

Wind erosion

Front 30

It is a permanent body of ice, which consists largely of recrystallized snow and shows evidence of movement due to gravity.

Back 30

Glacier

Front 31

The erosion process is dominant in ____________ and in high altitude mountains

Back 31

Polar regions

Front 32

is caused by the detachment and transport of soil by rainfall, runoff, melting snow or ice, and irrigation.

Back 32

Water

Front 33

True or false

Glacier is the most common agent of erosion since it can pick-up millions of tons of sediments every day

Back 33

False - Water

Front 34

It is the downslope movement of rock, soil, and ice due to the force of gravity

Back 34

Mass wasting ( mass movement )

Front 35

It is also a natural hazard that can cause damage to life and property

Back 35

Mass wasting ( mass movement )

Front 36

Give 4 causes of mass wasting

Back 36

Increased steepness

Increased water

Decreased vegetation

Earthquakes

Front 37

It is the process in which sediments settle out of the transporting medium

Back 37

Deposition

Front 38

What do you call the areas where sediments are deposited?

Back 38

Sedimentary environment can be _______ give 6

Back 39

Glacial

Desert

Lake

River

Delta

Beach

Shallow/ deep marine environment
