An atom is the smallest particle of a substance that has all the properties of the substance.
Every atom is composed of a nucleus and one or more electrons which are bound to the nucleus. The nucleus is made of one or more protons and a number of neutrons as well. Only the most common variety of hydrogen has no neutrons in it.
The electrons of an atom are attracted to the protons in an atomic nucleus through the electromagnetic force. The protons and neutrons in the nucleus are attracted to each other with the help of nuclear force. This force is usually stronger than the electromagnetic force which repels the positively charged protons from one another in the nucleus. Under certain circumstances, the repelling electromagnetic force between protons become stronger than the nuclear force. In this case, the nucleus splits and leaves behind different elements. This is a type of nuclear decay.

Answer:
Burning fossil fuels is different from other processes that cycle carbon in environments on Earth in the following ways:
Speed: Burning fossil fuels releases carbon dioxide into the atmosphere much more quickly than other natural processes. For example, it takes millions of years for carbon dioxide to be released from rocks and sediments through natural processes, but fossil fuels can be burned in a matter of seconds.
Scale: The amount of carbon dioxide released into the atmosphere from burning fossil fuels is much greater than the amount released from other natural processes. In 2019, humans emitted about 38 billion tons of carbon dioxide into the atmosphere, of which about 89% came from burning fossil fuels.
Location: Burning fossil fuels releases carbon dioxide into the atmosphere in specific locations, such as cities and power plants. This can lead to high concentrations of carbon dioxide in certain areas, which can have negative impacts on human health and the environment.
Other processes that cycle carbon in environments on Earth include:
Photosynthesis: Plants use carbon dioxide from the atmosphere to produce food.
Respiration: Plants and animals release carbon dioxide into the atmosphere when they breathe.
Decomposition: When plants and animals die, their bodies are decomposed by bacteria and fungi, which release carbon dioxide into the atmosphere.
Weathering: Rocks and sediments are weathered over time, releasing carbon dioxide into the atmosphere.
Volcanic eruptions: Volcanic eruptions can release large amounts of carbon dioxide into the atmosphere.
These natural processes cycle carbon between the atmosphere, land, and oceans. The carbon cycle is a natural process that has been happening for millions of years. However, human activities, such as burning fossil fuels, are disrupting the carbon cycle and causing carbon dioxide levels in the atmosphere to rise. This is leading to climate change, which is having negative impacts on the planet and its inhabitants.
To reduce the impact of burning fossil fuels on the carbon cycle, we can transition to renewable energy sources, such as solar and wind power. We can also improve energy efficiency and reduce our reliance on fossil fuels.
