module 4

• Electromagnetic Spectrum


  Range of frequencies of electromagnetic radiation and their respective wavelengths and photon energies
• Climate change refers to long-term changes
• Specific heat is the amount of heat energy required to increase the temperature of water
• Water molecule is slightly charged on both ends due to polarity
• Soil is composed of minerals, soil organic matter, living organisms, gas, and water
• Non-essential nutrients can be made by the body or have replacement nutrients
• Weather refers to short term atmospheric conditions
• Properties of Water

  Water (H2O) is a polar inorganic compound, tasteless and odorless liquid, described as the "versatile solvent"
• Cohesion creates surface tension in water
• Abiotic factors in ecosystems

  • Solar Radiation
  • Electromagnetic Spectrum
  • Climate vs Weather
  • Properties of Water
  • Heat of Vaporization
  • Surface Tension
  • Air
  • Soil Composition
  • Minerals Found in Soil
  • Nutrients
• Heat of vaporization is the heat required to change water from liquid to gas
• Nutrients are chemical substances found in foods used by organisms
• Solar Radiation

  Electromagnetic radiation emitted by the sun, can be captured and turned into useful forms of energy
• Climate is the weather of a specific region averaged over a long period of time
• Surface tension in water is due to unbalanced hydrogen bonding
• Water is by far the most studied chemical compound
• Adhesion allows water molecules to be held to another substance
• Essential nutrients cannot be synthesized by the body and must be ingested
