Earth's interior
primary source of carbon on Earth
Carbon (C)
from the latin "Carbo" meaning coal
Carbon Cycle
the series of processes by which carbon compounds are interconverted in the environment, transformed from organic carbon to inorganic carbon and back again
Carbon cycle processes
involve the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels
Carbon Dioxide
CO2 - a gas found in the atmosphere, soils and oceans
CH4 - gas found in the oceans, atmosphere, soils and sedimentary rocks.
Calcium Carbonate
CaCO3 - a solid compound found in calcareous rocks, oceans, and in the skeletons/shells of sea creatures
A compound of hydrogen and carbon, such as any of those which are the chief components of petroleum and natural gas, usually found in sedimentary rocks
complex carbon compounds produced in living things e.g. proteins, carbohydrates, fats and oils, DNA
Anthopogenic CO2
carbon dioxide generated by human activity
the sum total of all living matter on Earth
Carbon sequestration
The capture of carbon dioxide from the atmosphere or capturing anthropogenic CO2 from large scale stationary sources such as power stations before it is released into the atmosphere
Carbon sink
A store of carbon that absorbs more carbon than it releases
Greenhouse Gas
Any gaseous compound in the atmosphere that is capable of absorbing infrared radiation, thereby trapping and holding heat in the atmosphere
The breakdown of rocks insitu by a combination of weather, plants and animals. Releases Carbon into the atmosphere
Inorganic carbon
Carbon that is found in non living matter such as the oceans, the atmosphere, the soils and rocks
Organic carbon
Carbon that is found in living matter such as palnts and animals
