Answer:
(D) Burning fossil fuel moves carbon from geosphere to the atmosphere.
Explanation:
The geosphere includes all of the land sediments such as oil deposits and rocks.
Carbon is released into atmosphere by many means like
• Inside an animal body, carbon from nutrients and foods consumed and carbon dioxide is released as waste
• When an animal dies, bacteria and fungi convert much of the carbon in it's body into carbon dioxide.
• Plants use sun energy to absorb carbon dioxide from atmosphere and convert it into sugars in order to grow, essentially storing the carbon in their leaves and tree trunks.
When we burn that plant material such as a log, the burning releases carbon stored in log as carbon dioxide.
I hope this will help you : )
