Hello

Question 1

What is crude oil?

Answer 1

A fossil fuel and a mixture of hundreds of different compounds, mainly hydrocarbons

Crude oil is used to make fuels for transport, heating, and generating electricity.

Question 2

What elements do hydrocarbons contain?

Answer 2

Carbon and hydrogen

Hydrocarbons are the primary components of crude oil.

Question 3

What are the main hydrocarbons found in crude oil?

Answer 3

Alkanes

Alkanes contain a single chain of carbon atoms with hydrogen atoms bonded alongside.

Question 4

How is crude oil formed?

Answer 4

From the remains of marine plants and animals that died millions of years ago

These remains are buried under layers of sand and mud, preventing decay.

Question 5

What happens to the remains of marine organisms to form crude oil?

Answer 5

They are buried in layers of sedimentary rock, increasing heat and pressure over millions of years

This process breaks down the remains into molecules that form crude oil and natural gas.

Question 6

Where is crude oil found?

Answer 6

Trapped in rocks of the sea bed and oil rigs or drilling platforms

Oil is extracted by drilling through the sea bed.

Question 7

What happens after oil is removed from the sea bed?

Answer 7

It is pumped through pipelines to an oil tanker terminal or an oil refinery on land.

Question 8

Is there a concern about running out of oil?

Answer 8

Yes, there are over 1 trillion barrels proven in oil reserves, but usage increases each year

It is uncertain when reserves will run out.

Question 9

What are some environmental problems associated with crude oil?

Answer 9

Burning products produce gases and particles that contribute to global warming and air pollution

Additionally, oil spills and slicks are damaging to wildlife and the environment.

Question 10

What is a significant socio-political issue related to crude oil?

Answer 10

High value of oil can cause military conflict, especially since large amounts come from politically unstable countries.

Question 11

Is crude oil useful in its raw form?

Answer 11

No, it must be refined and processed in a refinery.

Question 12

What is the purpose of refining crude oil?

Answer 12

To separate compounds in the oil into fractions, each containing a mix of compounds with a similar number of carbon atoms.

Question 13

Crude oil = fossil fuel

Question 14

= mixture of hundeeds of diff. compoonds

Answer 14

masty hydrocarbons

Question 15

=used to make fuels for transport

Answer 15

heating + genenting electricity

Question 16

= Cused to make plasties + 1005 of types of cheMicals)

Question 17

Hydrocarbons = only contain

Question 18

the elements

Question 19

Carbon + hydrogen → Many compounds in crude o

Question 20

Mast hydrocarbons in crude oll =alkanes → contain a Single chain of cabon

Question 21

ahar atoms a hydrogen atoms bonded along side

Question 22

Crude oil

Question 23

made: from remains of narine plants + animals that died millions of

Question 24

years ago.

Question 25

Remains =

Question 26

SOAk to

Question 27

bottom of sea → buried in layers of sand + mud → preventing them

Question 28

from

Question 29

rotting → these loyers eventually became Sodimentery rock.

Question 30

over millions of yes layers of rock build up → increasing heat + pressure

Question 31

Causing =

Question 32

cassi remains to be broken down into molecures

Question 33

that form Crude

Question 34

oil + natural gas

Question 35

Found: trapped in rocks of

Question 36

the sea bed + oil rigs or drilling platforms

Question 37

dril

Question 38

through the sea bed to obtain it (the oil).

Question 39

After : oil is removed from sea bed

Answer 39

pumped in cong pipelines to an oi

Question 40

tanker

Question 41

terminal or an oil refinery on land.

Question 42

Will it run out: over I trillion barrels proven in ail reserves → lost abt 6o years

Question 43

ail useage in word

Answer 43

increase each year so unsure when it'll run out

Question 44

Problems: Buming products of crade ail as fuel → produces gases + particles which

Question 45

contribute to global warming tair pollution

Question 46

• Removing oil from ground + oil spillages + slicks → very damaging to wildile + the

Question 47

envirenment

Question 48

• High value → cause of military conflict. Large amount of ail comes from

Question 49

politically unstable countries.

Question 50

Useful? Itsely = not usagul → has to be refined processed done in an finery

Question 51

- Seperate compounds in

Question 52

the oil into fractions

Question 53

- each compound fraction: contains a mix of compounds la similar no. of carbon

Question 54

atoms
