Science

• Natural Resources


  Materials created and used by humans to survive and satisfy their needs from nature
• Types of Natural Resources

  • Renewable
  • Non-Renewable
• Renewable Resources


  • Can grow back again once consumed
• Non-Renewable Resources


  • Cannot be grown back once consumed
• Atmosphere


  The blanket of envelope of gases surrounding the earth
• Layers of the Atmosphere

  • Troposphere
  • Stratosphere
  • Ozone Layer
  • Mesosphere
  • Thermosphere
  • Exosphere
• Troposphere


  • Decreases in temperature as altitude increases
• Stratosphere


  • Flow of air increases in altitude, more stable (75% mass), contains ozone layer
• Ozone Layer


  • Protects humans from ultraviolet radiation from the sun
• Thermosphere


  • Closer to the sun and absorbs a large amount of solar radiation
• Exosphere


  • Very cold, transitions to the vacuum of space
• Greenhouse Effect


  Warms the earth's surface, without it the earth would be very cold
• Enhanced Greenhouse Effect


  Higher presence of greenhouse gases traps and reflects more heat back to the earth's surface, can lead to global warming
• All living things are affected by global warming and changes in weather patterns
• Land Surface


  • Heats up faster than bodies of water during the day, loses heat faster than bodies of water during the night
• Sea Breeze


  • Occurs during the day when land warms faster than the sea, air flows from sea to land
• Land Breeze


  • Occurs during the night when land cools faster than the sea, air flows from land to sea
• Monsoons


  Involve larger air masses, abundant rainfall to a country
• Monsoons


  Occur when air moves toward the place where warm air is rising, the area of rising warm air is called a low pressure area
• High Pressure Area


  Area where cold air sinks
• Rotation


  Planet spins around an invisible line (circular)
• Revolution


  Earth revolves in orbit around the sun, completing one revolution in a year
• Solar Eclipse


  Occurs when the moon passes between the Earth and Sun, blocking the sun's light
• Types of Solar Eclipses

  • Total Solar Eclipse
  • Partial Solar Eclipse
  • Annular Solar Eclipse
• Lunar Eclipse


  Occurs when the Earth passes between the Sun and Moon
• Types of Lunar Eclipses

  • Total Lunar Eclipse
  • Penumbral Lunar Eclipse
  • Partial Lunar Eclipse
• The three main types of cells are plant, animal, and bacteria.
