1 Canada’s Physical Geography
noun The study of the physical features of the earth and its atmosphere, and of human activity as it affects and is affected by these, including the distribution of populations and resources, land use, and industries.

7 Layers of the Earth https://www.youtube.com/watch?v=NAHY6965o08

8 Planet Earth The Earth is made up of 3 layers: the core, the mantle, and the crust. The Earth is made up of layers of rock of different ages. Canada has some of the oldest rock – about 4 billion years old!

9 Core Outer core – very hot and contains mostly liquid rock.
Center of the Earth composed of 2 layers: Inner core – very hot and solid because it’s under tremendous pressure. Outer core – very hot and contains mostly liquid rock.

10 Mantle The middle layer is the thickest layer of the Earth.
It is made of solid rock, although high temperature and pressure can cause some of this rock to turn into hot, dense, slow moving liquid rock known as Magma.

11 Crust The surface of the Earth, the part we walk on, is thinner under the oceans, and thicker under the continents.

12 Convection currents move air, water, and magma
Heat rises Cold drops Causes a rotation of substance being warmed and cooled. /what-are-convection-currents- definition-examples-quiz.html

13 Project Building Pangea “Gizmos”

14 It is believed the world was once one giant super continent called Pangaea. Over time, the plates of Pangaea started to move apart creating the continents we know today.

15 Continental Drift Scientist Alfred Wegener came up with this theory.
The theory that the Earth’s plates are moving. The earth's crust is divided into plates that move because of convection currents in the earths mantle.

16 Pangea Progression

17 Theories are great but…..
What evidence do you think may prove Wegener’s theory? It’s a puzzle…

18 Scientists found evidence of continental drift to support their theory:
1. The fit of the continental landmasses. 2. Similar fossils in rocks on separate continents. 3. Fossils of sea animals found high in the Himalaya Mountains.

19 Plate Tectonics The concept of Convection currents and plate movement is know as plate tectonics. Canada is located on the North American Plate. It moves about 4 centimeters west every year. When the Pacific plate moves northeasterly it creates a subduction zone.

20 Subduction zone when one plate slides beneath another creating volcanoes and earthquakes.

21 “Ring of Fire” The zone around the Pacific Ocean is called the “Pacific Ring of Fire.” More than half of the world’s active volcanoes above sea level are found in this zone. The scary part is that the same area has some of the most densely populated regions on the planet!

22 1/5 of Canada's thousand or so earthquakes happen in British Columbia.
Movements of the plates also means that the distance between the Atlantic provinces and Western Europe is increasing every year.

23 Assignment: Questions
What is the reason for the nickname “Pacific Ring of Fire?” Explain why Eastern Canada experiences relatively few major earthquakes.

24 Landforms READ Page 23 to 26

25 What land/water features are you familiar with?
All these form Geography!

26 Title Text Picture Sample layout
Project Landforms G-Classroom Assignment Research your assigned landform. Make a slide show presentation that includes the following pages: 1.Title page 2. A description of your landform. 3 key points and picture 3. How it was made or shaped. 3 key points and picture. 4. Where in Canada can you find this landform? 3 examples with pictures. 5. Reference page (site at least 3 sources where you found information) Pictures on every page! Sample layout Fjord – Glacier – Strait – Sand spit – Plateau – Canyon – Basin – Delta – Waterfall – Archipelago– Inlet – Oxbow lake – Peninsula- Title Text Picture

28 Landforms or Topography
natural features of the land’s surface (topographic maps) Hills, valleys, rivers, lakes, oceans, etc.

29 Landscape Made up of an area’s landforms and includes vegetation, water, ice, rock, human and animal activity. Landscape effects how we live: Food, travel, communication, business, etc.

30 There are two types of Landscape:
1. Urban landscape city 2. Rural landscape country

31 How are Landforms Built? See page 24 in text!
Building up forces of mountain building Wearing down forces of weathering Wearing down forces of erosion Building up forces of deposition

32 Currents under the crust sometimes cause the magma in the mantle to come to the surface as lava.
When this happens, great trenches or large mountains can form.

33 Landforms are also created when continental plates move apart or collide.
Fault lines cracks in the earth’s crust that usually run between the plates

34 Weathering The gradual breaking down of solid rock by air, water, animals, and plants.

35 Erosion When the land’ surface is carried away by running water, tides, wind, and glaciers.

36 Deposition When eroded particles are dropped off in one place by running water, tides, wind and glaciers.

37 What is a Rift Valley? Draw a rift valley in your notes

38 The Great Rift Valley

44 Project Mapping Canada Project
You’re assigned Province _________________________________________ You and a partner will research using text book, atlas, and internet: Step #1 On your photo copied map do a rough copy of all the info below. Year province entered Confederation Capital Population 2 tallest mountains and any mountain ranges. Major bodies of water; rivers, lakes and oceans. Climate regions Major industries Step #2 Draw your province onto Bristol board, cut it out and fill in the information above: Step #3 When complete we will post all provinces in order to make a Class Map of Canada. From the “class map of Canada” you will fill in your own Canada map for your notebook with the following: Province Bodies of water Mountain ranges
