More generation of radiocarbon through detonation of nuclear weaponry-->circulation in the atmosphere of radioactive neutrons, which react with atmospheric 14-nitrogen to form 14-carbon.
Human activity affects the natural carbon cycle mainly through the burning of fossil fuels, deforestation, and land-use changes. These activities release excessive amounts of carbon dioxide into the atmosphere, leading to an imbalance in the carbon cycle and contributing to global warming.
Some non-human activities that release carbon into the atmosphere as CO2 during the carbon cycle include volcanic eruptions, wildfires, and the decomposition of organic matter in soils. These processes release carbon that has been stored in rocks, vegetation, or soil back into the atmosphere.
The carbon cycle has the most significant impact on global warming. This cycle involves the movement of carbon through the atmosphere, oceans, and land, with human activities like burning fossil fuels leading to increased levels of carbon dioxide in the atmosphere, causing the Earth's temperature to rise.
The carbon cycle has the most significant impact on Earth's temperature. The increasing concentration of carbon dioxide in the atmosphere from human activities, such as burning fossil fuels, contributes to the greenhouse effect and leads to global warming.
Human activities like deforestation slows down the process of water cycle. It harms the environment as a whole.
One false statement regarding the carbon cycle is that human activities have no impact on altering the balance of carbon between different reservoirs. In reality, activities such as burning fossil fuels and deforestation have significantly increased the amount of carbon dioxide in the atmosphere, leading to climate change.
There are a few human activities that would have a direct impact on the oxygen-carbon dioxide cycle. Planting trees and other plants is one of these activities.

Humans are responsible for the increase in carbon in the atmosphere primarily due to activities such as burning fossil fuels, deforestation, and industrial processes. These activities release carbon dioxide and other greenhouse gases, leading to the greenhouse effect and climate change. Additionally, human activities have disrupted the natural carbon cycle, leading to an imbalance in carbon levels in the atmosphere.
The carbon cycle has the most significant impact on global warming. This cycle involves the movement of carbon through the atmosphere, oceans, and land, with human activities like burning fossil fuels leading to increased levels of carbon dioxide in the atmosphere, causing the Earth's temperature to rise.
The oxygen cycle is least affected by human activities.
Carbon enters the carbon cycle through various processes such as photosynthesis by plants and algae, respiration by living organisms, volcanic eruptions releasing CO2, and the decay of organic matter by decomposers. Human activities such as burning fossil fuels and deforestation also contribute to the carbon cycle.
The carbon cycle is vulnerable today due to human activities such as burning fossil fuels and deforestation, which are releasing more carbon dioxide into the atmosphere than natural processes can remove. This imbalance is leading to an increase in atmospheric carbon dioxide levels, contributing to climate change and disrupting the delicate balance of the carbon cycle.
The carbon cycle has the most significant impact on Earth's temperature. The increasing concentration of carbon dioxide in the atmosphere from human activities, such as burning fossil fuels, contributes to the greenhouse effect and leads to global warming.
Human activities effect a nutrient cycle by increasing the amounts of nutrients in the cycle faster then natural biotic and abiotic processes can move them back to the stores.
