Answer:
Step-by-step explanation:
Combustion of fossil fuels: Burning coal, oil, and natural gas to produce energy releases carbon dioxide (CO2) into the atmosphere.
Other processes that can release carbon into the air include:
Deforestation: Trees absorb carbon dioxide through photosynthesis, and cutting down forests can release the carbon stored in the trees and soil.
Volcanic activity: Volcanic eruptions can release carbon dioxide and other greenhouse gases into the atmosphere.
Decomposition: When organic matter such as plants, animals, and other living organisms decompose, they release carbon dioxide and other gases into the atmosphere.
Ocean outgassing: The ocean absorbs and releases carbon dioxide as part of its natural cycles, and some of this carbon can be released into the air.
It's important to note that while some of these processes are natural, human activities such as burning fossil fuels and deforestation have significantly increased the amount of carbon dioxide in the atmosphere, leading to climate change.
