  1. Cycling of Matter

  2. Water Cycle • Hydrosphere- water of Earth’s surface • Water Cycle- movement of water in the hydrosphere, driven by sunlight

  3. Hydrological Cycle

  4. Biochemical Cycles • Oxygen • Carbon • Nitrogen • Phosphorous

  5. Nitrogen & Carbon Cycle

  6. Nitrogen Cycle • Describes the transformations of nitrogen and nitrogen-containing compounds in nature. It is a cycle which includes gaseous components. • Earth's atmosphere is about 78% nitrogen, making it the largest pool of nitrogen. • Nitrogen is essential for many biological processes; it is crucial for any life here on Earth. It is in all amino acids, is incorporated into proteins, and is present in the bases that make up nucleic acids, such as DNA and RNA.

  7. Nitrogen Cycle Movement of Nitrogen between atmosphere, bacteria and other organisms

  8. Oxygen Cycle • the movement of oxygen within and between its three main reservoirs: • atmosphere (air), • biosphere (living things) • lithosphere (Earth's crust). • The main driving factor of the oxygen cycle is photosynthesis, which is responsible for the modern Earth's atmosphere and life.

  9. Oxygen Cycle

  10. Carbon Cycle The cycle is usually thought of as four major reservoirs of carbon interconnected by pathways of exchange. These reservoirs are: • The atmosphere. • The terrestrial biosphere, which is usually defined to include fresh water systems and non-living organic material, such as soil carbon. • The oceans, including dissolved inorganic carbon and living and non-living marine biota, • The sediments including fossil fuels

  11. Phosphorous Cycle • Describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere. • Unlike many other biogeochemical cycles, the atmosphere does not play a significant role in the movements of phosphorus, because phosphorus and phosphorus-based compounds are usually solids at the typical ranges of temperature and pressure found on Earth.

  12. Natural Leaching

  13. Human Impact

  14. Phosphorus Cycle Movement of phosphorus from the environment to organisms and back
