Cycles of Matter

  Nitrogen Cycle Nitrogen Nitrogen is the element with the symbol N and its atomic mass is 14.0067 u. Nitrogen Cycle The nitrogen cycle is a biochemical process through which nitrogen  is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere. It involves several processes such as nitrogen fixation , nitrification, denitrification, decay and putrefaction.

  Oxygen Cycle Oxygen  Oxygen is the element with the symbol O and its atomic mass is 15.999 u. Oxygen Cycle The oxygen cycle is the biochemical transitions of oxygen  atoms between different oxidation states in ions, oxides, and molecules through red ox reactions within and between the spheres reservoirs of the planet Earth.

  Carbon Cycle Carbon  Carbon is a the element with the symbol C and atomic mass 12.01. Is the building block of living things, so its mean that we are made from carbon atoms. Carbon Cycle The carbon cycle describes the process in which carbon  atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon  in this system does not change.

Water Cycle  Water is a chemical substance that its the fluids of all known living organisms. Its chemical formula is H2O meaning that each of its molecules are made of two hydrogen atoms and one oxygen atom. The water cycle describes how water  evaporates from the surface of the earth, rises into the atmosphere, cools and condenses into rain or snow in clouds, and falls again to the surface as precipitation.  The cycling of water  in and out of the atmosphere is a significant aspect of the weather patterns on Earth.
