Why were thick coal deposits not found in coastal deposits and deltas that formed during earlier times?
Why were thick coal deposits not found in coastal deposits and deltas that formed during earlier times?
- The coastal swamps were too shallow to support the growth of coal-forming plants.
- There was excessive volcanic activity that prevented the formation of coal deposits.
- The climatic conditions were not suitable for the formation of coal deposits.
- The plants that produced enough biomass to form large peat deposits had not yet evolved. (correct)
What led to the decrease in carbon dioxide (CO2) concentrations during the Carboniferous period?
What led to the decrease in carbon dioxide (CO2) concentrations during the Carboniferous period?
- Extensive deforestation and land use changes
- Intense solar radiation leading to CO2 breakdown
- Rapid ocean acidification due to increased volcanic activity
- The growth of continental glaciers caused by global cooling (correct)
What has contributed to the reversal of the carbon dioxide removal process in recent times?
What has contributed to the reversal of the carbon dioxide removal process in recent times?
- Large-scale deforestation leading to reduced biomass production
- Significant reduction in industrial emissions and human activities
- The exploitation of large reserves of coalbed methane (correct)
- Increased volcanic activity releasing stored CO2 from the Earth's crust
