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.

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.

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
