HISTORY OF CARBON THIS ELEMENT OF PREHISTORIC

DISCOVERY IS FOUND THROUGHOUT NATURE

FOUND IN STARS, SUN, COMETS, ATOMSPHERES

THE ENERGY OF THE SUN AND THE STARS CAN BE ATTRIBUTED TO THE CARBON CYCLE

3 TYPES OF CARBON CARBON CAN BE

FOUND IN THREE DIFFERENT FORMS:– GRAPHITE– DIAMONDS– FULLERENE (aka

BUCKYBALLS)

CARBON AS GRAPHITE

GREAT GRAPHITELAYERED ATOMIC STRUCTURE-

THERFORE PRODUCES A WEAK FORCE, AND IS EXTREMELY BREAKABLE

SOFT, SLIPPERYMOST COMMONLY USED AS PENCIL

LEAD

CARBON DIAMONDS

DIAMOND DATADIAMONDS HAVE AN ATOMIC SHAPE

THAT ENSURES A TIGHT BONDEACH CARBON ATOM IS THE SAME

DISTANCE FROM ANOTHER ATOMDIAMONDS ARE USED FOR CUTTING

HARD OBJECTS AND FOR DECORATION (JEWELERY)

FULLERENE-ALSO KNOWN AS

THE ‘BUCKYBALL”-RECENTLY

DISCOVERED-CONSISTS OF 60

CARBON ATOMS-C60

-STILL BEING RESEARCHED

“BUCKYBALL” THIS COMPLEX MOLECULE CAN BE ALTERED

WITH A SINGLE ATOM TO CHANGE ITS PROPERTIES

NAMED AFTER ROBERT BUCKMINISTER FULLER

THIS MOLECULE HAS BEEN MAKING HEADLINES IN NANOTECHNOLOGY AND HOW THE DRUG INDUSTRY HAS INTEREST IN IT

COSTS OF CARBON

-AS OF 1990, CARBON-13 WAS COMMERICIALLY AVAILABLE AT A COST OF ABOUT $700/GRAM.

CARBON CYCLE

CARBON IN THE LITHOSPHERE PLANTS ABSORB

CARBON DIOXIDE FROM ATMOSPHERE, AND USE IT TO MAKE SUBSTANCES NEEDED FOR GROWTH

PHOTOSYNTHESIS INCORPORATES CARBON ATOMS FROM C02 TO SUGARS

LITHOSPHERE CONT. ANIMALS (RABBIT) EAT PLANTS AND USE

CARBON TO BUILD TISSUES OTHER ANIMALS (FOX) EAT RABBIT AND

USE CARBON FOR OWN NEEDS ANIMALS RETURN C02 INTO AIR WHEN

THEY BREATHE, AND WHEN THEY DIE (BECAUSE CARBON IS RETURED TO SOIL DURING DECOMPOSITION)

CARBON IN THE HYDROSPHERE C02 ABSORBED INTO

BODIES OF H20 SOME OF DISSOLVED

C02 REMAINS IN WATER WHILE SOME IS USED BY ALGAE AND PHYTOPLANKTON THROUGH PHOTOSYNTHESIS

MOLLUSCS (MUSSELS, CLAMS AND OYSTERS) MAKE SHELLS OF CALCIUM CARBONATE FROM C02

HYDROSPHERE CONTINUEDONCE MUSSLES DIE, SHELLS FALL

TO BOTTOM WITH HARD CALCIUM CARBONATE AND BECOMES COMPRESSED, CEMENTED TOGETHER, AND EVENTUALLY FOSSILISED INTO ROCKS LIKE CHALK, LIMESTONE, AND MARBLE

CARBON IN THE ATMOSPHERE COMBUSTION

OCCURS WHEN ORGANIC MATERIAL IS REACTED (BURNED) IN PRESENCE OF OXYGEN TO GIVE OFF C02

-DURING CONBUSTION, OXYGEN IS USED AND CABON DIOXIDE IS PRODUCED PLUS WATER

SMOKESTACK ORGANIC

MATERIAL CAN BE ANY FOSSIL FUEL SUCH AS NATURAL GAS, (METHANE) OIL, OR COAL

PHOTOSYNTHESISCARBON

DIOXIDE+ WATER

(h20) -> CARBOHYDRATE+ OXYGEN

PHOTOSYNTHESIS

RESPIRATIONCARBOHYDRATE + OXYGEN-> CARBON DIOXIDE + OXYGEN

CALCIUM CARBONATE

CALCIUM CARBONATE-> CALCIUM OXIDE + CARBON DIOXIDE

OIL AND COAL WHEN TREES DIE,

THEY FALL INTO SWAMPY MUD, WITH A LACK OF OXYGEN. THEREFORE, NORMAL DECOMPOSITION CANNOT OCCUR

OIL AND COAL II TREES BECOME

FOSSILISED (COAL IS THEN FORMED)

OIL FORMS FROM TINY DEAD PLANTS TRAPPED AT THE BOTTOM OF THE OCEAN OR MURKY WATER

RELATE COAL TO CARBON THE PROCESS IN WHICH OIL AND

COAL ARE MADE, IS RELATIVE TO THE CARBON CYCLE BECAUSE ALL LIVING ORGANISMS AND THE PROCESSES ARE MADE UP OF CARBON

RECAP OF CYCLES

HYDROSPHERE, LITHOSPHERE, AND ATMOSPHERE AGAIN!

CARBON CYCLE, AS EASY AS 1, 2, 3…

COMPLEX CARBON CYCLE

WHERE THE CYCLE BEGINS… THE ATMOSPHERE CONTAINS CARBON

DIOXIDE THROUGH THE PROCESS OF

PHOTOSYNTHESIS, PLANTS TAKE IN CARBON, CONTINUING THE CYCLE IN THE LITHOSPHERE

WHEN PHOTOSYNTHESIS EXCEEDS RESPIRATION, ORGANIC MATTER BUILDS UP TO FORM COAL AND OIL DEPOSITS

“The major exchange of carbon between the atmosphere and the

lithosphere results from photosynthesis and

respiration”

CARBON AND RESPIRATION RESPIRATION IS PART OF THE PROCESS

OF THE CARBON CYCLE IN THE LITHOSPHERE

ONCE ANIMALS BREAK DOWN CARBOHYDRATES IN PLANT TISSUES, THEY RELEASE IT TO THE ATMOSPHERE (THE CYCLE THEN CONINUES BACK TO THE LITHOSPHERE OR GOES TO THE HYDROSPHERE)

CARBON AND RESPIRATION CONTINUED

WHEN ANIMALS RELEASE CARBON DIOXIDE TO THE ATMOSPHERE, THEY DECOMPOSE, DECAY, AND FROM POOLS OF ENERGY CALLED FOSSIL FULES (INCLUDING COAL, OIL, AND NATURAL GASES)

CARBON IN THE HYDROSPHERE

CARBON IS ABSORBED IN THE WATER BY PHYTOPLANKTON TO MAKE SHELL OF CALCIUM CARBONATE AND BECOME SEDIMENTS ONCE THEY DIE

CARBON IN HYDROSPHERE CONT.

CARBON DIOXIDE EXCHANGE IS CONTROLLED BY THE SEA SURFACE TEMPERATURE, CIRCULATING CURRENTS, AND THE BIOLOGICAL PROCESS OF PHYTOSYNTHESIS AND RESPIRATION

MORE CARBON IN HYDROSPHERE CARBON DIOXIDE CAN DISSOVLE EASILY

AND THE AMOUNT THAT THE OCEAN CAN HOLD DEPENDS ON THE OCEAN TEMPERATURE AND HOW MUCH CARBON IS ALREADY IN THE OCEAN

WHEN THE OCEAN IN COLD, MORE CARBON IS ARBORBED, AND WHEN THE TEMP. IS WARM, CO2 IS RELEASED TO THE SURFACE

THE GREENHOUSE EFFECT

CARBON DIOXIDE CONTRIBUTES

THE GREENHOUSE EFFECT

KEEPS ALL EARHT’S HEAT FROM ESCAPING TO THE OUTER ATMOPSHERE

CARBON RESPONSIBLE FOR GREENHOUSE GASES AND 55% OF THE GREENHOUSE EFFECT

CARBON DIOXIDE IS TRANSPARENT TO LIGHT BUT OPAQUE TO HEAT RAYS, THEREFORE THE ATMOSPHERE RETARDS THE RAIATION OF HEAT FROM THE EARTH BACK INTO SPACE

GREENHOUSE EFFECT
