The Effects Of Carbon And On Fossil Fuels - 1022 Words.

Carbon Cycle And Its Effect On Earth 1461 Words6 Pages The four cycles important to ecosystem are water, carbon, nitrogen, and phosphorous. The Water cycle describes the movement of water on Earth through evaporation, transpiration, condensation and precipitation.

The greenhouse effect is when the gases in Earth’s atmosphere trap heat onto Earth and stop it from going to space. The main greenhouse gases are carbon dioxide, methane, and nitrous oxide.Burning fossil fuels is the main reason global warming is increasing. When we burn fossil fuels, we are releasing carbon dioxide.

Effects of Changing the Carbon Cycle All of this extra carbon needs to go somewhere. So far, land plants and the ocean have taken up about 55 percent of the extra carbon people have put into the atmosphere while about 45 percent has stayed in the atmosphere.Carbon enters the atmosphere as carbon dioxide from respiration and combustion. Carbon dioxide is absorbed by producers to make carbohydrates during the process of photosynthesis. Animals feed on.The carbon cycle is dynamic, and is fully interactive with the climate. The earth's climate changes as a result of changes in the abundance of CO2 in the atmosphere; climate change in turn changes the dynamics of carbon exchange among the reservoirs and causes shifts in the atmospheric CO 2 levels.


Because some carbon gases are greenhouse gases, changes in the carbon cycle that put more carbon in the atmosphere also warm Earth’s climate. On the short time scale, the carbon cycle is most visible in life. Plants on land and in the ocean convert carbon dioxide to biomass (like leaves and stems) through photosynthesis. The carbon returns to the atmosphere when the plants decay, are eaten.The other form of human alteration of the global carbon cycle is through forest cutting and burning and the disruption of soils associated with agriculture. When deforestation occurs, most of the plant matter is either left to decompose on the ground, or it is burned, the latter being the more common occurrence. This process reduces the size (the mass) of the land biota reservoir, and the.

Social and economic deterioration and mass migration will also occur as a result. Other areas will experience increased rainfall, causing flash floods.

The core goal of the carbon cycle research community in responding to the climate change challenge is to under-stand the role of the natural and managed carbon cycle in the dynamics of the climate system. That requires quan-tifying the effect of human activities on the carbon cycle (1); determining the response of natural systems to these disturbances; projecting future behavior of carbon.

Both natural and human factors can cause a change in the inputs of carbon into the atmosphere, oceans, biosphere and pedosphere. They can also affect the rates at which carbon is.

Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. As a result, the amount of carbon dioxide in the atmosphere is rapidly rising; it is already considerably greater than at any time in the last 800,000 years. The ocean absorbs much of the.

Carbon Cycle and Ecosystems is split into four different research programs that help focus and advance our understanding of the Earth: Biological Diversity Research Program The Biological Diversity Research Program uses NASA observations and models to improve our understanding of biodiversity, including how and why it is changing, and its effects on and interactions with the Earth system.

The carbon cycle is easiest to understand in terms of its processes and how carbon is converted. The three key processes and the conversions are shown in the table below. Carbon enters the.

These changes in atmospheric carbon dioxide have important implications for plants and the global carbon cycle as well as for climate. Atmospheric carbon dioxide is the raw material for terrestrial green plant photosynthesis, and thus it represents the first molecular link in the food chain of the whole earth. In later sections, we will examine the importance of carbon dioxide for.
