Which of the following statements is not true regarding the Great Oxygenation Event?
A
It caused a significant increase in atmospheric oxygen levels.
B
It occurred during the Cambrian Explosion.
C
It led to the formation of the ozone layer.
D
It resulted in the extinction of many anaerobic organisms.
Verified step by step guidance1
Identify the Great Oxygenation Event (GOE) as a significant geological event that occurred approximately 2.4 billion years ago, marking the first major increase in Earth's atmospheric oxygen levels.
Understand that the GOE is distinct from the Cambrian Explosion, which occurred much later, around 541 million years ago, and is known for the rapid diversification of life forms.
Recognize that the increase in oxygen levels during the GOE led to the formation of the ozone layer, which protected the Earth from harmful ultraviolet radiation.
Acknowledge that the rise in oxygen levels during the GOE was detrimental to many anaerobic organisms, leading to their extinction or adaptation to new environments.
Conclude that the statement 'It occurred during the Cambrian Explosion' is not true regarding the Great Oxygenation Event, as these are two separate events in Earth's history.
