carbon

Question 1

name and define the 3 parts of the carbon cycle💓🤍

Answer 1

Stores - Where carbon is held.
Fluxes - The flows of carbon between different stores. Fluxes differ in size.
Processes - The physical ways in which carbon fluxes happen.

Question 2

4 carbon stores?🌷

Answer 2

the hydrosphere (oceans)
the litosohere (rock surface and below)
the biosphere (above surface)
the atmosphere (in air)

Question 3

what is sequestration?🌲🌳💐☘️🌷🍃🌾

Answer 3

when co2 in the atmosphere is taken in by trees and plants during photosynthesis

Question 4

what is chemical weathering🌙

Answer 4

co2 combines with rainfall- produces carbonic acid
this dissolves carbon rich rocks- forming bicarbonates
deposited as carbon in the ocean

Question 5

what’s the biological carbon pump?🐬

Answer 5

phytoplankton sequesters co2 through photosynthesis
they create carbon shells as they develop
when they die they sink to the floor as sediment

Question 6

4 factors affecting energy consumption🔮

Answer 6

physically availability
cost
technology
political considerations

Question 7

4 energy players🪷🌾💐🍃

Answer 7

energy TNC’s eg shell
governments
consumers
OPEC

Question 8

what percentage of the global energy mix do fossil fuels make up💗

Answer 8

86%

Question 9

what’s an energy pathway?💕

Answer 9

the flow of energy between a producer and consumer eg pipelines

Question 10

what are 3 radical technologies in reducing carbon emissions☀️

Answer 10

carbon capture and storage
electric vehicles
hydrogen fuel cells

Question 11

what’s ocean acidification?🌸

Answer 11

as co2 increases ocean become more acidic
when ocean is too hot coral bleaching occurs

Question 12

name one goal of the 2015 paris agreement🌼

Answer 12

limit average global temperatures
support developing countries in reducing emissions
increase adaptation to climate caunge

Question 13

what’s the albedo effect?🐉

Answer 13

ice reflects radiation which reduces surface warming. melting ice means less is reflected which increases warming

Question 14

what impact does climate change have on permafrost and peatland?🪻

Answer 14

permafrost melts and release co2 and methane
peatlands warm drying and decomposing them so they release methane

Question 15

name 4 adaptation strategies🌻

Answer 15

water conservation and management
land-use planning and flood-risk management
resilient agriculture systems
solar radiation management

Question 16

name 5 mitigation strategies🌺

Answer 16

carbon taxation
energy efficiency
carbon capture storage
renewable switching
afforestation

Question 17

what are 3 losses that climate change causes to ocean health

Answer 17

loss of mangroves - they stabilise coasts against erosion, protect against extreme weather + provide fish nurseries
loss of food- warming water + ocean acidification are killing fish + causing coral bleaching -affects food +incomes for locals
loss of tourism-damage to corel reefs directly impacts income from tourism
