There are two major factors that we do to contribute; burning fossil fuels and using nitrogen based fertilizers. Carbon cycle. Carbon dioxide is being added to the atmosphere through two types of processes, (A) Biological i.e respiration and decomposition release carbon dioxide. Which statement most accurately describes the formation of fossil fuels? The substances which act as energy sources are known as fuels. B. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. The burning of fossil fuels from various industrial processes adds nitrogen and nitrous oxide compounds to the atmosphere, which upsets the balance of natural nitrogen, polluting ecosystems and altering the ecology of entire regions.This upset in the balance of the nitrogen cycle affects biological diversity. Answer. D. Water cycle. Fossil fuels formed between 300-400 million years ago from plant and animal remains Burning of fossil fuels affects. MEDIUM. Burning fossil fuel releases carbon dioxide, which goes into the atmosphere and enhancing the greenhouse effect. Human activities have a tremendous impact on the carbon cycle. Changes to the carbon cycle. Humans have a huge impact on the nitrogen cycle. It adds nitrogen to terrestrial ecosystems and leads to nutrient imbalance in trees, a decline in biodiversity, and changes in the health of forests. By burning fossil fuels and using these fertilizers there are great changes in the amount of nitrogen in the atmosphere that alter the water and land ecosystems. The buried organic matters which can be converted to crude oil, coal, natural gas or any heavy oils by applying pressure and heat on earth’s crust over hundreds of years are known as fossil fuels.This topic educates about the effect of burning fossil fuels on the environment. Burning Fossil Fuels This is the greatest source of atmospheric carbon from human activities. What are Fossil Fuels? Carbon stored underground in coal, oil, and natural gas deposits for millions of years is being released into the atmosphere very quickly, creating a major imbalance in the cycle. Burning fossil fuels results in a change in carbon storage, thus affecting the nitrogen cycle and other vital processes. Researchers have found a new proxy to measure the impact of fossil fuel emissions on the global nitrogen cycle. Acid rain is produced by the interactions of nitrogen and sulfur oxides that are put into the atmosphere from burning fossil fuels and industrial pollution, and the impacts of acid rain are controlled by many other element cycles on land and in the water. A. Nitrogen cycle. Burning fossil fuels alters the amount of nitrogen in the Earth's atmosphere. Learn more about fossil fuels, and they affect the climate. C. Phosphorus cycle. Impacts of Agricultural Nitrogen on the Environment and Strategies to Reduce these Impacts ... which has doubled the flux of N through the terrestrial N-cycle. a number of contributing factors that play an integral role in the climate change, fossil fuels are also responsible for changing the climate. Production of fertilizer-N, via the Haber-Bosch process, consumes an enormous amount of fossil fuel, and produces a matching amount of CO2.
