Carbon cycle

Question 1

What is Biofuel?

Answer 1

• Fuel made from living matter
• such as crops, forestry or fishery products or forms of waste
• Primary biofuel includes wood, fuelwood, and wood chips. Anything natural and unprocessed primarily for heating and cooking or electricity generation
• Secondary Biofuel, processing biofuels into ethanol and bio-diesel. Used in vehicles and industry

Question 1

What are Energy Pathways?

Answer 1

• Route an energy type is transferred from production to consumption areas such as a pipeline or a shipping route

Question 2

What are Fluxes?

Answer 2

• Movement or transfer of carbon between stores such as the atmosphere and the hydrosphere

Question 3

What is out-gassing?

Answer 3

• Release of gas stored or dissolved due to changes in heat or pressure
• Carbon is released by metamorphic activity at plate boundaries or hot spots

Question 4

What is sequestration?

Answer 4

• Processes where carbon is removed from atmosphere and storred in plants and soil ,absorption into oceans or through carbon capture and storage from power stations

Question 5

What are Petagrams and Gigatons?

Answer 5

• Units used to measure carbon equal to a billion tonnes or a trillion kilos

Question 6

What does Biogeochemical mean?

Answer 6

• Transfer of elements and compounds such as carbon, between living organisms and the physical environment through chemical processes that create new compounds and elements in the atmosphere, hydrosphere and lithosphere

Question 7

What is Biomass?

Answer 7

• Organic matter used as fuel, especially in power stations, especially in power stations

Question 8

What is phytoplankton?

Question 8

What is an energy mix?

Question 9

What are carbon fluxes?

Question 10

What are players?

Question 11

What is carbon neutral?

Question 12

What is energy security?

Question 13

What is ocean acidification?

Question 14

What is the enhanced greenhouse effect?

Question 17

Why is carbon important?

Answer 17

• Main constituent of all living cells (50% of all biomass, 18% of Human bodies)
• Can form long chained molecules which are the basis for fats, carbs, nucleic acids and proteins
• Component of fossil fuels needed for non-electric travel

– Use in nanotube for computers

• Element of our atmosphere making u the balance

Question 18

What is a carbon store?

Answer 18

• Places where carbon is held such as the atmosphere in a gaseous form

Examples include

• The atmosphere, CO2 and CH4
• The hydrospehere, Gaseous dissolved in water, forming shells marine animals
• The Liphosphere, Solid layer of the earth, carbonates in limstone and fossil fuels
• The cryosphere, Gaseous, dissolved in ice
• The Pedosphere, mainly in dead organic material

Question 19

What is a carbon flow?

Answer 19

The movement of carbon between carbon stores

Question 20

What is a carbon process?

Question 21

What is resevoir turnover?

Answer 21

• The rate at which carbon enters and leaves a store
