What is an upwelling?
Upwelling is the rising of nutrients to the surface due to the strong winds blowing the surface waters.

What vision problem does the following eyeball have and what type of lens could correct it?
Myopia, corrected with a diverging lens (negative meniscus).
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
Provide an example of a positive feedback loop and a negative feedback loop.

Calculate the speed of light in glass.
1.97 x 10^8 m/s
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
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.
Provide three pieces of evidence supporting climate change.
1) Changes in ecosystems 2) Severe weather patterns 3) Rising sea levels
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.

Write out the entire electromagnetic spectrum from the longest wavelength to the shortest wavelength.
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
Using the figure as a template, draw a diagram to show the critical angle and total internal reflection.

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)
