* The ‘cycle’ transform in 3 ways
* Erosion
* Ice
* Water
* Wind
* Heat
* Pressure
* Sediment

Rock material evolves under changing physical conditions at or beneath the earth’s surface

* Calcification
* As water evaporates, water from the bottom comes up. Nutrients and calcium gets drawn to the surface. That process creates a poisonous layer * Leaching
* Moves water through the soil and removes all of the nutrients

Theory of Continental Drift

* Alfred Wegener put forth the theory of continental drift in 1915

Jigsaw fit of continent
* Continent look like they could be fit almost perfectly
* See the east coast of South America and the West Coast of Africa

Climate Fit
* Scientist found evidence of glaciers in placed which no longer get snow * Striation (gouges in rock caused by glacial movement) found in the bedrock in India

Fossil Fit
* Scientist found fossil remains of certain animals and plants on both sides of the Atlantic * Somewhere fresh water species

Geological Fit
* Mountain ranges and soil samples were found it be similar on both sides of the Atlantic * Appalachian (N.A) & Caledonian (Scandinavia) Mountain ranges

Into the Earth
* As you travel towards the Earth’s core both temperature and density increases * Therefore, each layer of the Earth ‘floats’ on the layer below it * Convection current move the plates around

* Where plates meet/separate, earthquake, and volcanoes and mountain occurrence * All of this action occurs at the plate boundaries

Climate vs. Weather

Climate
* Long term pattern of weather
* 40 years per average
* Focus on temperature on precipitation
* Two primary types of climates
* Maritime
* Located close to large bodies of water
* Continental
* Located away from large bodies of water
* Climate affects
* Where we live
* What food we grow
* How we construct buildings
* Travel
* Major Climate events
* Ice age
* Global warming
* Drought

Weather
* Day to day condition of the atmosphere
* Weather Variables Reported:
* High/low temperature
* Wind Speed
* Precipitation
* Humidity
* Etc.
* Weather influenced
* Clothes we wear
* Activity we do
* Major weather events
* Hurricanes
* Tornadoes
* Heat waves
* Snow storm
* Etc.

Canada’s Eco zones

* A large scale region based on its unique ecological characteristics * Canada has 20 eco zones (15 terrestrial, 5 marines)
* Each eco zone is distinguished from other by its unique vegetation, wildlife, climate, landforms and human activities * Eco zones are useful for general national reporting, research and for placing Canada’s ecosystem diversity in a North American or global context

Longitude and Latitude

* The geographic canter of the world is the Gulf of Guinea off the west coast of Africa at 0º to 0º

Latitude
Definition

Primary line
Equator at 0º
* Divides the world into Northern Southern hemisphere

Other lines
Tropics
= Tropic of Cancer (Northern) = 23.5º N
= Tropic of Capricorn (Southern) = 23.5 º S

Circles
= Arctic Circle (Northern) = 66º N
= Atlantic Circle (Southern) = 66º S

Longitude
Definition
Imaginary lines running North/South dividing the world into degrees east/west of the Prime Meridian

179º179º
WE

Primary Line
Prime Meridian at 0º
* Divides the world into Eastern/Western hemispheres
* Runs through Greenwich, England

Other lines
International Date Line at 180º
* Zigzags around land through the Pacific Ocean
* If you cross the IDL moving west, you add a day
* If you cross IDL moving East, you subtract a day

Time zones

History
* Created by Sandford Fleming in the late 1900s
* Necessary response to the development of rapid transport and the fact that morning should be morning everywhere

How it works
* The earth rotates around its axis every 24 hours
* Therefore there’s 24 time zones
* Since the earth is 360º360º/24 time zones = 15º
* Therefore each time zone is 15º wide
* Every place within any single time zone is called Standard Time (S.T.) * The primary time zone is centered on the Prime Meridian is called Universal Time (U.T) * Canada has 5.5 time zones (Pacific, Mountain, Central, Eastern, Atlantic and Newfoundland) * The Earth is like a circle

* Therefore, is made up of 360º
* Takes earth 24 hours to rotate once or 360 degrees
* Considering there’s 24 time zones, each time zone is made up of 15º * 360/24=15
* The time zones in Canada are
* Pacific
* Mountain
* Central
* Eastern
* Atlantic
* Newfoundland

Colliding Continents

* The first rock that was formed and cooled was called a craton * 3.8 billion years ago, organisms began using photosynthesis * Convection Currents is what drives the plate tectonics
* The first super continent was named Valbara
* 1.1 billion ago another super continent was created and named Rodinia * The super continent created after Rodinia, was called Gondwana * After Gondwana, it was Pangaea
* The next super continent would be called Pangaea Ultima * A rift is when an area is breaking apart
* A super a continent can cause extreme weathers like hot summers and extremely cold winters along with creating an Ice Age * There’ll be another 250 years until another Super Continent

Canada’s Geologic History

* The earth is 4.6 billion years old
* 87.6% of the earth’s age is the Precambrian Era
* The Canadian Shield was created
* Looked like many mountains
* Made up of Igneous, metamorphic, and some sedimentary * Now, newer mountains replace the old one
* Created by faulting and folding
* 0.7% was the Paleozoic Era
* Erosion happened and sediments moved across the Shield * It moved across the rivers and sedimentary rocks were created * The three most important things we find in this rock is: * Oil

* Gas
* Coal
* Pangaea was also created
* Along with the Appalachian mountains
* Then the extinction of all plants and animals
* Mesozoic Era took up 3.9% of the years
* Pangaea started to break up
* Mostly seas and swamps covered Canada
* The Rocky Mountains started to form
* Dinosaurs lived on the east to this region
* Found limestone and fossils for proof
* To protect that site, there’s now a provincial park around it * To end the era, there was a massive extinction
* Theory is that an asteroid collided with the earth * 1.4% of the years are to the Cenozoic Era
* During this Era, Canada became the landforms they are now * 2 million years ago there was a big Ice Age
* It was signified by glaciers
* The Great Lakes were then created
* Large amounts of clay, silt, sand and gravel were dumped into the lowlands * It also created the current patterns of the lakes, rivers, hills, and plains * There was 4 to 5 glacial periods in the era

* The glaciers are not found in the Arctic and Mountains * The extinction of the dinosaurs happened
* Along with the increase of mammals and water
* Pollution increase
* More lakes, rivers, and dams

The power of Ice

* Avalanches make very little damage
* Ice makes more damage
* For snow to change into rock hard ice, it’ll take 20 years * Glaciers are known to me near most mountains
* Antarctica’s ice sheet is approximately 4 km thick
* Nowadays, we are considered to be in an Ice Age
* Because North America and South America joined, creating little islands, the warm water was forced to rush up stream into the Gulfs * Which brought moisture to the cold regions
* Resulting more snow
* In the last million years the ice advanced about 8 times * Glaciers move
* The last ice age began approx. 100000 -> 6000
* And ended 1-2 million -> 6000
* The ice advanced and retreated 4 times
* There is two kinds of glaciers
* Alpine
* Continental

The Great Lakes

* It’s 10 000 years since glaciers have been in Southern Ontario * The great lakes were created by
* Ice depressed land
* Rock inside glacier scraped out land
* Glaciers retrieved
* Melted ice filled the holes

Climate Key Terms

* Climate Graph
* Show the temperature (line) and precipitation (bar) characteristics for a climate station * Average Temperature
* Add the monthly temperatures and divide it by 12
* Temperature Range
* The difference between the lowest and highest temperature * < 25º C = Maritime
* > 25ºC = Continental
* Total Precipitation
* Add the total precipitation
* Indicated whether a climate station is dry or wet
* >1000mm – Maritime
* <1000mm – Continental
* Seasonal Distribution
* Indicates the season (winter or summer) that generates the majority of precipitation * Winter = Maritime
* Summer= Continental
Precipitation

* During condensation, the vapor cools and changes from invisible gas to liquid water * Condensed vapor creates clouds
* As air rises, it cools down and expands due to less air pressure

Relief Precipitation
* Is also known as an Orographic Precipitation
* As air passes over a mountain
* The air becomes colder
* The moisture expands and cools
* As the cloud rides over the mountains, and expands, it lets out rain * Therefore, there’s more rain on the windward than the leeward

Convectional Precipitation
* This current precipitation is more involved with summer * It’s most experienced at the Prairie Provinces, Ontario, and Quebec * The precipitation can be dangerous due to the fact it causes tornadoes * Other weathers could be thunderstorms or hail

Cyclonic Precipitation
* Also referred to Frontal Precipitation
* Mostly occurs in the Winter
* An extreme example is a Blizzard

Vegetation

* In the North regions, where the Tundra is, the land is basically frozen. * This is also known as Permafrost
* Tundra and the Boreal & Taiga forest is separated by the tree line * Marks the Northern boundary of the tree growth
* Recognized by the needle leaved trees
* For example Black Spruce and Balsam Fir and Pine
* The Grasslands are basically grass
* Cordilleran is very different from the others
* Above the tree line there’s meadows of flowers and shrubs * Hot dry valleys it’s hot and contain cactuses
* In the West Coast Forest is mild and moist
* Deciduous Forest is the warmest
* Mixed forest is a transition zone between the boreal forest and deciduous * Therefore there’s coniferous and deciduous trees

Factors Affecting Climate in Canada

Latitude
Elevation
Air masses
Prevailing winds
Nearest to water
Ocean currents
Landforms
Learn Everything about Parachuting Not Only Landing

* Latitude
* The closer you are to the Equator the warmer it is
* The sun gives off the same energy, it Is just stretched over a distance * Therefore, it takes more to warm up Canada then Africa * Elevations
* The higher you get, the colder it becomes
* The air expands as it gets higher
* As it expands it loses heat
* Air Masses
* Knowing the volume of the air mass it will give a better understanding of how hot, cold or dry the air is * Over the ocean, the air mass has more moisture
* As it rises it releases the moisture, creating rain * Because continental isn’t near a large body of water, it’s dry * Prevailing Winds
* The winds tend to move the air masses from West to East * High and low pressure belts created established patterns of the wind * Nearest to water
* Air masses that originate over water will contain more moisture and will be cooler in the summer and warmer in the winter * Ocean Currents
* Climates are affected by the point of origin of the ocean currents * Temperature of an ocean current affect the temperature of the air mass passing over it * Landforms
* Air masses are heavy with moisture
* As the air mass pass over mountains it lets go of the moisture and rain falls * At the top, the rain will become snow
* As the air comes down from the other side, the air mass will be dry and cause little precipitation

Global Warming/Climate changes

* Positives
* More land can be used (North)
* Tourism
* Longer growing season
* Warmer winters
* Negatives
* Increases diseases
* Cancer
* Respiratory problems
* Etc.
* Potential ice age triggers
* Increased natural disasters
* Loss of habitat and wildlife species
* Global warming is the average increase in the Earth’s temperature * Climate change is a naturally occurring event that includes both warming and cooling * Some greenhouse gases (GHG) are:

* Nitrogen
* Oxygen
* Methane
* Nitrous oxide
* Water
* Carbon Dioxide
* GHG became a problem during
* The industrial revolution
* Oil burned for engines heat energy
* Fossil Fuels
* Released GHG
* Increased pollution
* Global Warming
* One of the big GHG in Canada is
* Tar sands
* Creates 10x amount of GHG than regular crude
* Every year we add 25 billion tons of Carbon into the atmosphere * Temperatures are predicted to rise between 1.4ºC to 5.8ºC over the next century * With global warming we’ll see
* Floods
* Droughts
* Storms
* Hurricanes
* Fires
* Melting ice
* Fish population decreases
* Animal extinction
* Habitat loss
* Displacement
* Agriculture problems
* New goal is to pump the carbon back where it needs to be

Scales

* Our magic number is 100 000
* There is 100 000 cm in 1 km
* Ratio Scale
* 1:200 000
* It means that 1 unit on the map is equal to 200 000 of the same units on the earth surface * Statement Scale
* 1cm = 2km
* If the distance measured between two places on the map is 1 cm =, the actual distance on the earth’s surface is 2 km * Linear Scale
* 02468

* The line is divided into units (km) that represent the actual unit on the ground. In this case 1 cm represents 2 km on the earth’s surface

Essay Organizer

Thesis: The increase of immigration is good for Canada

Argument 1: It increases the multiculturalism in the country Support 1: In the 21st century, approximately 200,000 immigrants come to Canada each year. All of these people bring their own language, culture, and religion with them to Canada. Support 2: Immigrants or descendants of immigrants make up 98% of Canada

Argument 2: Wider job range
Support 1: In 2006, Canada received 236,756 immigrants. It is in the obvious that they all would be looking for a job to support themselves and/or their families. Thus the creations of different jobs Support 2: The percentage of a Canadian holding a job increased from 41.6% to 51.3%

Argument 3: The economy becomes better
Support 1: The employment rate is 63.6%
Support 2: in 2008 there’s a percentage of 11.7% with part time jobs while there’s 51.9% with full time jobs

Conclusion: Therefore, immigration to Canada would benefit the country a lot.
