Carbon-14 Dating: an Invaluable Yardstick in the Chronology of Humans Archeologists use many methods to analyze data from the past. One scientific tool they use is to analyze the radioactive decay of chemical elements found in plant and animal remains‚ pottery‚ and even in rocks. Radiocarbon dating‚ also known as carbon-14 dating‚ has been one of the most important radioisotope dating methods used. This scientific tool‚ which was first developed by Willard F. Libby in the late 1940s‚ has significantly

Carbon‚ Phosphorus and Nitrogen Cycles Humans have a great impact on each of the Carbon‚ Phosphorus‚ and Nitrogen cycles in the Ecosystem. The carbon cycle starts with the reservoir of the carbon dioxide in the air‚ the carbon atoms move from carbon dioxide through photosynthesis into atoms of organic molecules that form the plants body. These carbon atoms are then further metabolized and are eaten and turned into tissue that all organisms in the ecosystem use. Half of the atoms are respired

Black carbon is one of the top ten contributory to global and regional warming. Due to the lack of major companies failing to adhere to strict state and local guidelines. These studies have shown the mixing of aerosols and black carbon traveling many miles from 3 to 5 kilometers‚ causing the carbon dioxide emissions to exceed normal regional and local state levels. Many people are medically affected from upper respiratory illnesses/ allergy issues. This effect causes people to lose time from work

changed from a net importer to a net exporter of rice‚ albeit on a small scale. In the 1980s‚ however‚ rice production encountered problems. Average annual growth for 1980-85 declined to a mere 0.9 percent‚ as contrasted with 4.6 percent for the preceding fifteen years. Growth of value added in the rice industry also fell in the 1980s. Tropical storms and droughts‚ the general economic downturn of the 1980s‚ and the 1983-85 economic crisis all contributed to this decline. Crop loans dried up‚ prices

Adventures of Zircon and Carbon Zircon and Carbon were brothers from the Triangulum Galaxy. They are two twin aliens that stood 6’7 and were a stunning color of mint green. They traveled 2.7 light years to get to Earth for a special mission. The mission was currently unknown. They were rushed on to a spacecraft and only sent with coordinates and supplies to lead them along the way. The coordinates they had read “Latitude: -64.15164‚ Longitude: -10.58414‚ Distortion: 5.26.” The spacecraft finally
