Answer:
Ways that carbon can get from seashells to the atmosphere:
First: Crashing of tectonic plates.
Second: Odd belching of volcanos.
Third: Cement Production, it will release carbon to the atmosphere.
Explanation:
Carbon from living organisms can end up deep underground. Over very long periods of time and huge pressure the carbon from seashells from things like long-dead coral become limestone.
With natural conditions, it can take millions of years to go back to the atmosphere the Carbon with natural geological and chemical process such as:
First: Crashing of tectonic plates.
Second: Odd belching of volcanos.
Besides that, we can have other processes such as:
Third: heating limestone to produce cement, it will release carbon to the atmosphere.
Finally, we can conclude that the Ways that carbon can get from seashells to the atmosphere:
First: Crashing of tectonic plates.
Second: Odd belching of volcanos.
Third: Cement Production, it will release carbon to the atmosphere.
