During the Carboniferous period, which occurred approximately 360 to 300 million years ago, most of Earth was covered in dense rainforests. These rainforests were sustained by a humid and tropical climate that lasted for most of the Carboniferous period. At the end of the period, Earth's climate became much colder and drier, leading to a wide-scale collapse of the rainforests and a significant loss of vegetation.

How might the collapse of the Carboniferous rainforests have affected Earth's carbon cycle?
A.
Over millions of years, the decaying vegetation would have been buried and its carbon turned into fossil fuels.
B.
Over time, the decaying vegetation would have absorbed a large amount of carbon dioxide from the atmosphere.
C.
The total amount of carbon in the carbon cycle would have increased as the vegetation decayed.
D.
The loss of vegetation would have decreased the total amount of carbon in Earth's carbon cycle.

Atmosphere and climate. There areseveral hypotheses about the nature and cause of the Carboniferous Rainforest Collapse, some of which include climate change. ... Thecarboniferous period is characterised by the formation of coal deposits which were formed within a context of the removal of atmospheric carbon.

Over time, the decaying vegetation would have absorbed a large amount of carbon dioxide from the atmosphere. thanks

Answer:

A. Over millions of years, the decaying vegetation would have been buried and its carbon turned into fossil fuels.

Explanation:

This is the most accurate description of how the collapse of the Carboniferous rainforests have affected the Earth's carbon cycle. Fossil fuels are the result of the anaerobic decomposition of vegetation that died and sedimented in large quantities. This occurred millions of years ago, and thanks to high levels of heat and pressure the organic matter was chemically altered, resulting in the creation of fossil fuels.
