1) What warms the planet?
The radiation from the sun is what warms the planet. Its energy warms up particles in the atmosphere and it radiates down towards the surface of the earth.

2) Referring to this diagram explain why the equatorial regions receive more radiation and therefore are warmer than polar regions.
The sun doesn’t heat the Earth evenly due to the fact that the Earth is a sphere and the sun heats equatorial regions more than polar regions.

3) Define Albedo. Which would absorb more radiation a snow covered mountain or a black roof?
Albedo is the fraction of solar energy reflected from the earth back into space. It is a measure of the reflectivity of the earth's surface. A black roof would absorb more radiation from the sun because the colour black absorbs all colour and heat unlike the smoother surface of snow and the white colour which would reflect the radiation.

4) Explain lapse rate.
The lapse rate is defined as the rate at which atmospheric temperature decreases with the increase in altitude.

5) Explain Aspect. In the Northern Hemisphere will plants grow better on the north or the south side facing side of a mountain?
An aspect relates to the direction in which a place is facing and it only affects local climates. South facing slopes receive more sunlight than north ones which is much more proficient for plant growth and survival.
6) Why do we have seasons?
We have seasons because the Earth is tilted as it makes its yearly journey around the sun. The Earth’s axis is tilted at an angle of 23.5 degrees, so it is always “pointing” to one side as it goes around the sun. The sun is in the direction that the Earth is pointing sometimes, so this varies the amount of sunlight around the Earth during the year, creating seasons.

7) Which heats up faster: Land or Water?
Land heats up faster because water is lighter and more reflective, as it reflects the rays of the sun making it more difficult to heat, also keeping in mind that the molecules of water are always in motion making it more difficult for the sun to heat up the water in a uniform motion.

8) Describe the impact that being far away from water has on the climate of the prairies
The impact of being far away from water in the prairies makes the climate extremely cold during winters and extremely hot during summers and dry throughout both seasons as there is no moisture in the air and bodies of water aren't present to regulate temperatures.

9) Explain the impact of the Gulf Stream on Norway.
The chaotic currents warms Norway as its choppy and rapidly moving waters brings the warmth from the atmosphere from the tip of Florida up to Norway.

10) What current runs past BC?
The current that runs past BC is called North Pacific.

11) Describe the impact of adding extra carbon dioxide to the atmosphere on the temperatures of Earth.
Adding extra carbon dioxide to the atmosphere increases temperatures of the earth as it creates greenhouse gases that traps the sun rays, trapping the heat and causing global warming.

12) Describe convection. THIS IS IMPORTANT TO UNDERSTAND AS WE MOVE THROUGH THE COURSE
Convection is the movement caused within a liquid where the hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.

13) What is wind?
Wind is the natural movement of air, in the form of a current of air blowing from a particular direction.

14) Explain urban heat islands, and explain why they occur.
Urban heat islands are metropolitan areas that are a lot warmer that its surrounding rural areas caused by human activities.
