the carbon cycle at a variety of scales

Question 1

the carbon cycle - plant

Answer 1

between the plant and the atmosphere

Question 2

the carbon cycle - sere

Answer 2

between the stages of plant succession

Question 3

the carbon cycle - continental

Answer 3

on a global scale between oceans and continents

Question 4

how long does carbon take in the slow carbon cycle

Answer 4

takes between 100-200 million years to move between rocks, soil, ocean and atmosphere in slow carbon cycle

Question 5

the movement of carbon from the atmosphere to the lithosphere

Answer 5

begins with rain
atmospheric carbon combines with water to form a weak acid
acid dissolves rocks
rivers carry dissolved ions to oceans

Question 6

what happens in the oceans ?

Answer 6

calcium ions combine with bicarbonate ions to form calcium carbonate

Question 7

how does the slow cycle return carbon to the atmosphere?

Answer 7

through volcanoes
plates one sinks beneath the other melts under extreme heat and pressure and heated rock recombines into silicate minerals releasing co2

Question 8

the fast carbon cycle

Answer 8

the fast carbon cycle is largely the movement of carbon through life forms on earth or the biosphere

Question 9

what happens during photosynthesis in relation to the fast carbon cycle?

Answer 9

during photosynthesis plants absorb co2 and sunlight to create fuel this process forms the basis of the fast carbon cycle

Question 10

the fast carbon cycle…

Answer 10

is so tightly tied to plant life that the growing season can be seen in the way carbon dioxide fluctuates in the atmosphere
