causes of change in the carbon cycle

Question 1

what are the 2 natural processes which would cause change in the carbon cycle

Answer 1

wildfires and volcanic activity

Question 2

how do wildfires cause change in the carbon cycle

Answer 2

carbon is transferred from the biosphere to atmosphere as carbon dioxide is released through burning. wildfires have an important role in the carbon cycle as they can cause growth in plants in the long term but they also have many threats.

Question 3

how does volcanic activity cause change in the carbon cycle

Answer 3

the carbon which is stored within the earth is released during volcanic eruptions, this carbon is mainly carbon dioxide gas.

Question 4

what are the human impacts which cause change in the carbon cycle

Answer 4

fossil fuel use, deforestation, farming practices

Question 5

how does deforestation cause change in the carbon cycle

Answer 5

often used to clear land for farming/housing, rapidly releases carbon stored in plants using slash and burn techniques and interrupting the forest carbon cycle

Question 6

how does fossil fuel use cause change in the carbon cycle

Answer 6

combustion transfers carbon dioxide to the atmosphere from a long-term carbon sink
