Which significant event in evolution occurred during the Carboniferous Period?
The Carboniferous saw the assembly of one of Earth's largest supercontinents, Pangea. All of the Earth's land masses combined into a singular continent causing major changes in ocean circulation.
What major event happened during the Carboniferous Period?
The later half of the period experienced glaciations, low sea level, and mountain building as the continents collided to form Pangaea. A minor marine and terrestrial extinction event, the Carboniferous rainforest collapse, occurred at the end of the period, caused by climate change.

What happened with the atmosphere during the Carboniferous?
As plants became firmly established on land, life once again had a major effect on Earth's atmosphere during the Carboniferous Period. Oxygen made up 20 percent of the atmosphere—about today's level—around 350 million years ago, and it rose to as much as 35 percent over the next 50 million years.
What were atmospheric co2 levels like from the beginning to end of the Carboniferous?
In the Early Carboniferous, global atmospheric carbon dioxide levels were around 1,500 parts per million, astronomical in comparison to modern values. However, carbon dioxide levels had decreased to around 350 parts per million by the Middle Carboniferous.Apr 24, 2020
Why did co2 decrease in the Carboniferous?
Abstract. The bulk of Earth's coal deposits used as fossil fuel today was formed from plant debris during the late Carboniferous and early Permian periods. The high burial rate of organic carbon correlates with a significant drawdown of atmospheric carbon dioxide (CO2) at that time.
What is the Carboniferous Period also known as?
"Carboniferous Period" is also known as "Age Of Amphibians".
