Why was there so much more carbon dioxide in the atmosphere during the cretaceous period as compared to your current atmosphere?

The Deccan Traps (an igneous super plume) released a large amount of subterranean CO2, raising atmospheric concentrations of this gas between 4 and 14 times modern pre-industrial values. Earth's climate warmed between 3 and 8 degrees C as a result of this gas.
Much if this CO2 was eventually sequestered in coal seams, reducing earth's temperature over the subsequent Cenozoic Era.

What is the role of the atmosphere in the carbon cycle?
Nature produces the vast bulk of carbon dioxide in the atmosphere. Rotting trees, and dead matter produce over 90% of the current levels of carbon dioxide. Man produces between 3 and 6 percent of all CO2 annually.
Where does co2 loading occur?
- carbon dioxide is released in the atmosphere: - part of carbon dioxide in the atmosphere is absorbed by the biosphere - part of carbon dioxide in the atmosphere is absorbed by body of waters
Is the Carbon dioxide changing by the same amount each year?
The current level of CO2 in our atmosphere is 390 parts per million. We are now releasing CO2 at astonishing rates into our atmosphere, so to answer your question no. More Carbon Dioxide is being put into our atmosphere each year. There is an average, but that has gone up in the past few decades.
What is the principal gas in the venusian atmosphere and also a minor component of the atmosphere of earth and mars?
Carbon dioxide. That's not quite right because carbon dioxide is about 95% of the atmosphere of Mars.
Where is Venus most carbon dioxide located?
Venus has a thick atmosphere composed mostly of carbon dioxide (CO2). This carbon dioxide is found throughout the atmosphere of the planet, with the highest concentration occurring in the lower atmosphere. It is estimated to make up about 96.5% of the atmosphere.
The current atmosphere is made mostly out of this gas?
carbon dioxide
What is the current atmosphere of Earth believed to be?
Earths atmosphere is made up mostly of oxygen and carbon dioxide.
Does Mars have a thin atmosphere?
Mars does have a thin atmosphere. Compared to the Earth's atmosphere, Mars' atmosphere is 100 times less dense. It is made up of mostly the elements carbon dioxide and nitrogen.
The earth would get warmer if you release more dioxide gas into the atmosphere?
As the current theory states - yes.
What two gases make up the bulk of the Earth's current atmosphere?
Nitrogen makes up most of the atmosphere. I am not sure which comes in second place, oxygen or carbon dioxide. I know our levels of carbon dioxide is rapidly increasing on this planet.
What planet has a thick carbon dioxide atmosphere?
Venus has the thickest carbon dioxide atmosphere.
What is the role of the atmosphere in the carbon cycle?
Nature produces the vast bulk of carbon dioxide in the atmosphere. Rotting trees, and dead matter produce over 90% of the current levels of carbon dioxide. Man produces between 3 and 6 percent of all CO2 annually.
Terrestrial planet with a thin carbon dioxide atmosphere?
Mars is the terrestrial planet with a thin carbon dioxide atmosphere. Venus also has an atmosphere of carbon dioxide, but it is very thick.
Where does co2 loading occur?
- carbon dioxide is released in the atmosphere: - part of carbon dioxide in the atmosphere is absorbed by the biosphere - part of carbon dioxide in the atmosphere is absorbed by body of waters
What is a natural source of sulfur dioxide carbon dioxide and ash in the atmosphere?
Volcanos release sulfur dioxide, carbon dioxide, and ash to the atmosphere at the same time
Does Soils emit carbon dioxide into the atmosphere?
Yes, I think soil can emit carbon dioxide into the atmosphere.
The process of decay releases carbon dioxide into the atmosphere?
The process of decay releases carbon dioxide into the atmosphere
