Sect 13.2

  1. 1. 6 th Grade Science Chapter 13 The Nonliving Environment Notes Section 13.2 Chimney Rock, North Carolina
  2. 2. <ul><li>What are the cycles of matter? </li></ul><ul><li>Earth’s biosphere contains a fixed amount of water, carbon, nitrogen, oxygen, and other material that cycle through the environment. </li></ul><ul><li>What is evaporation? </li></ul><ul><li>Evaporation takes place when liquid water changes into water vapor and enters the atmosphere. </li></ul>Key Questions 1
  3. 3. Biosphere 2 is a world-renowned environmental and ecological research site operated by the University of Arizona, and located near Oracle ,
  4. 4. Evaporation from oceans and lakes
  5. 5. <ul><li>What is condensation? </li></ul><ul><li>Condensation is the process of water changing from a gas to a liquid. </li></ul><ul><li>What is the water cycle? </li></ul><ul><li>The water cycle is a model that describes how water evaporates from the Earth and condensates from the air. </li></ul>Key Questions 2 The Tadpole Galaxy
  6. 6. Condensation
  7. 7. When an aircraft breaks the sound barrier, an unusual cloud sometimes forms in its wake. A drop in pressure, in this case due to shock wave formation, causes a sharp drop in temperature, leading water vapor to condense into droplets and form the cloud.
  8. 8. Condensation <ul><li>The water cycle is a model that describes how water moves from the surface of Earth to the atmosphere and back to the surface again. </li></ul>
  9. 10. Water Use <ul><li>The amount of water people take from reservoirs, rivers, and lakes for use in households, businesses, agriculture, and power production </li></ul>can reduce the amount of water that evaporates into the atmosphere.
  10. 11. <ul><li>Why is nitrogen necessary for life? </li></ul><ul><li>Nitrogen is a necessary ingredient in proteins and DNA. </li></ul><ul><li>What is the nitrogen cycle? </li></ul><ul><li>The nitrogen cycle is the transfer of nitrogen from the air to the soil, to living organisms, and back to the air. </li></ul>Key Questions 3 The Sombrero Galaxy
  11. 12. DNA Strands require Nitrogen to form Nitrogen fixation by Red Clover
  12. 13. The Nitrogen Cycle <ul><li>When dead organisms decay, the nitrogen in their bodies returns to the soil or to the atmosphere. </li></ul>
  13. 14. Soil Nitrogen <ul><li>Most fertilizers contain the kinds of nitrogen compounds that plants need for growth. </li></ul><ul><li>Compost and animal manure also contain nitrogen compounds that plants can use. </li></ul><ul><li>Fertilizers can be </li></ul>used to replace soil nitrogen in crop fields, lawns, and gardens.
  14. 15. <ul><li>What is the carbon cycle? </li></ul><ul><li>The carbon cycle describes how carbon atoms move between the living and nonliving world. </li></ul><ul><li>How do producers and consumers move carbon? </li></ul><ul><li>Producers remove CO 2 from the air during photosynthesis and consumers produce CO 2 during respiration. </li></ul>Key Questions 4
  15. 16. The Carbon Cycle <ul><li>Carbon is an important part of soil humus, which is formed when dead organisms decay, and it is found in the atmosphere as carbon dioxide gas (CO 2 ). </li></ul>
  16. 21. <ul><li>Describe the water cycle. </li></ul><ul><li>Infer how burning fossil fuels might affect the makeup of gasses in the atmosphere. </li></ul><ul><li>Explain why plants, animals, and other organisms need nitrogen? </li></ul><ul><li>Most chemical fertilizers contain nitrogen, phosphorous, and potassium. If they do not contain carbon, how do plants obtain carbon? </li></ul>Questions Section 13.2
