Unit 2-Atmosphere Test Flashcards
How could climate change affect Natural resources in Canada?
A warmer climate could create risks for our forests including unwanted pests, diseases and forest fires. Also, more frequent severe weather could damage our forests. Since the climate would be warm, Ice will melt causing see levels to rise and damage our water sources. Soil could also become more dry hurting our agricultural system.
How does climate change affect our health in Canada?
Greenhouse gases trap heat and light in the atmosphere creating more very hot days. Therefore, air pollution problems would increase, raising risk for respiratory problems in elderly and children especially. Also, many people people could get heatstroke or breathe in unhealthy gases such as CO2 because photosynthesis could break down. People could experience more allergies also.
How does climate change affect agriculture and future food supplies in Canada?
With a warmer climate, more species of animals or insects could invade our agriculture. Unnwanted pests could harm the farms and diseases and fires could occur. On the contrary, more opportunities to grow different foods in different places will be presented. For example, if climate became warmer up north we could farm there.
How does climate change affect our coastal areas?
A warmer climate could mean more severe and more frequent weather including droughts, winter storms, and tornadoes. This could create damage to towns and cities. A good example of this is the past flood in Calgary. We would also experience harsher summers and winters.
How does climate change affect our economy?
More pests and diseases in our agricultural system could cause a decrease in money contributing to our economy. Severe weather can cause damage to major cities with high costs for repairs. Repairing cities along the coast that have been eroded or flooded also would cost a lot of money. We also may need to relocate which would majorly affect our economy.
How does climate change affect other subjects such as animals and native species and their habitats?
With forest fires, severe weather and flooding damage due to climate change, habitats of important species could be destroyed and our ecosystem would take a huge toll.
LOWERN? What makes climate?
Latitude Ocean currents Winds (prevailing) Elevation Relief barriers Near large bodies of water
How does latitude affect temperature?
The further from the equator (north or south), the cooler the temperatures.
How does latitude affect precipitation?
The closer to the polls (higher the latitude), the lower the precipitation since cooler air holds less moisture than warmer air.
How do ocean currents affect temperature?
When warm, they raise temperatures along the coast (especially in winter) and when cold, they lower temperatures (especially in summer).
How do ocean currents affect precipitation?
When warm, they helped to create wet coastal climates. When cold, they help create drier coastal climates.
How do winds affect temperature?
When they move off large bodies of water on to land, they moderate temperatures and when they move off large land areas, they bring more extreme temperatures.
How do winds affect precipitation?
When they move off ocean areas onto land, they bring moisture and when they move from large land areas, they bring drier conditions. In Canada, they prevail from the west (Westerlies).
How does elevation affect temperature?
The higher you go, the cooler and it gets and vice versa.
How does elevation affect precipitation?
The higher you go, the more precipitation you’re likely to get.
How do relief barriers affect temperature?
They block winds and air masses so temperatures from one side to the other can be quite different (moderate on the Oceanside, more extreme on the continental side).
How do relief barriers affect precipitation?
Windward areas (facing the ocean) are wet since moist winds are forced to rise, cool, and release their moisture and leeward areas (facing away from the ocean) are dry, as winds descend, warm-up, and evaporate moisture.
How does the location near large bodies of water affect temperature?
Temperatures are moderated by the ocean (cooler summers/warmer winters), especially when winds move off of the ocean inland, and are more extreme (hotter summers/colder winters) when areas are located far inland away from oceans.
How does the location near large bodies of water affect precipitation?
Precipitation is higher next to oceans, especially when winds move off oceans inland onto mountains, and lower when areas are located far inland, especially when they are behind mountain barriers.

Maritime vs. continental
Maritime
- AKA coastal climate
- EX. Vancouver, Halifax, St.John’s, Victoria and Halifax
- Heavy precipitation
- Small range of temperature
- Mild summers and winters
- Maritime climates are near large bodies of water and that has a moderating affect on temperature
Continental
- AKA Inland climate
- EX. Calgary, Edmonton, Winnipeg, and Regina
- Little precipitation
- Large range of temperature
- Seasonal extremes
Weather vs. climate
- Day to day conditions of the atmosphere
- Characteristics include…
- precipitation (snow, rain, etc.)
- cloud cover (sunny/overcast)
- wind speed and direction
- temperature
- ozone number/UV index
- relative humidity
Climate
-Average weather conditions of a certain place over a long period of time (weather over 30 years).
How to calculate things on climographs
Annual average temperature: all temp. data \ 12
Total annual precipitation: sum of all precipitation data
Temperature range: max. temperature-min. temperature
Season of maximum precipitation: add all precipitation in season
Summer: April to September
Winter: January to March/October to December
How to eliminate carbon dioxide in our atmosphere?
Switching to fluorescent lightbulbs, wind turbines, solar panels, energy and water efficient appliances, fuel-efficient vehicles, carpooling, be energy-efficient by turning off lights and water when not using, dry laundry by air inside of a dryer, bike or walk, eat less processed foods, recycle, and plant more trees
What are Canada’s seven climate regions?
Arctic, sub-arctic, Pacific, Mountain, prairies, lower lakes, Atlantic
What climate region do we live in?
Lower lakes
How does precipitation occur?
–Warm air with moisture rises causing it to cool and condense, forming clouds.
-clouds become heavy with precipitation and it begins to fall.
