Question

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

Answer 1

The correct answer is D

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

Step-by-step explanation:

The carboniferous period is characterised by the formation of coal deposits which were formed within a context of the removal of atmospheric carbon.
