  • What type climate information do ice cores provide?
    Amount of precipitation, presence of volcano eruption, types of isotopes in the atmosphere, types of plant/animal species
  • Draw the ray diagram for the following question and describe the image using SALT.
    See teacher
  • Provide three pieces of evidence supporting climate change.
    1) Changes in ecosystems 2) Severe weather patterns 3) Rising sea levels
  • Draw the ray diagram for the following question and describe the image using SALT.
    See teacher
  • Write out the entire electromagnetic spectrum from the longest wavelength to the shortest wavelength.
    Radiowaves > Microwaves > Infrared Light > Visible Light > UV Light > X Rays > Gamma Rays
  • Draw the following diagram and describe the image using SALT.
    See teacher.
  • What is an upwelling?
    Upwelling is the rising of nutrients to the surface due to the strong winds blowing the surface waters.
  • Explain the El Nino effect. What does Canada feel?
    The weakening of trade winds every 2-7 years causing the warming of surface water on the west coast of S. America. Canada experiences milder winters.
  • List and explain the three factors that are involved in the Milankovitch Cycles.
    Eccentricity – Shape of the orbit; Obliquity - tilt of the Earth; Precession - wobble
  • Using the figure as a template, draw a diagram to show the critical angle and total internal reflection.
    See teacher.
  • Provide an example of a positive feedback loop and a negative feedback loop.
    See teacher
  • What is albedo and how is it related to climate change?
    Albedo is the measure of how much light is reflected off a surface. As snow melts, more land is exposed leading to lower albedo and higher temperatures.
  • What vision problem does the following eyeball have and what type of lens could correct it?
    Myopia, corrected with a diverging lens (negative meniscus).
  • Draw the formation of the prevailing winds on Earth.
    See teacher.
  • Calculate the speed of light in glass.
    1.97 x 10^8 m/s
  • Draw the ray diagram for the following question and describe the image using SALT.
    See teacher
  • Define the following and give an example for each of the following terms: a) Incandescence b) Phosphorescence
    a) production of light due to high temperatures (ex: lava) b) object absorbs and emits light slowly (ex: glow-in-the-dark)
  • Calculate the following and describe the image formed using SALT. Leave your final answers in mm. A 1m tall shrub is located 10m from a camera lens (converging lens). The lens as a focal length of 25mm.
    S - smaller; A - inverted; L - 25mm from lens; T - real
