Carbon key words

Question 1

Anthropogenic CO2

Answer 1

Carbon dioxide generated by human activity.

Question 2

Biosphere

Answer 2

The total sum of all living matter.

Question 3

Carbon sequestration

Answer 3

The capture of carbon dioxide (CO2) from the atmosphere or capturing anthropogenic (human) CO2 from large - scale stationary sources like power plants before it is released to the atmosphere. Once captured, the CO2 gas (or the carbon portion of the CO2) is put into long term storage.

Question 4

Carbon sink

Answer 4

A store of carbon that absorbs more carbon than it releases.

Question 5

Greenhouse gas

Answer 5

Any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere.

Question 6

Lithosphere

Answer 6

The crust and the uppermost mantle; This constitutes the hard and rigid outer layer of the Earth.

Question 7

Weathering

Answer 7

The breakdown of rocks in situ by a combination of weather, plants and animals.

Question 8

Enhanced greenhouse effect

Answer 8

the impact on the climate from the additional heat retained due to the increased amounts of carbon dioxide and other greenhouse gases that humans have released into the Earth’s atmosphere since the industrial revolution.

Question 9

Geo - sequestration

Answer 9

the technology of capturing greenhouse gas emissions from power stations and pumping them into underground reservoirs.

Question 10

Radiative forcing

Answer 10

The difference between the incoming solar energy absorbed by the Earth and energy radiated back to space.

Question 11

Soil organic carbon (SOC)

Answer 11

the organic constituents in the soil: tissues from dead plants and animals, products produced as these decompose and the soil microbial biomass.
