Physical Geography Unit 2 Agenda of Big Ideas • Natural environmental characteristics, such as climate, geology, drainage patterns, and vegetation, define the physical regions of Canada. • Canada’s Ecozones • Geological, climatic, and hydrological processes, phenomena, and events have shaped, and continue to shape, Canada’s natural landscape. • Geological processes (plate tectonics, earthquakes) Agenda of Big Ideas • Natural environmental characteristics, such as climate, geology, drainage patterns, and vegetation, define the physical regions of Canada. • Canada’s Ecozones • Geological, climatic, and hydrological processes, phenomena, and events have shaped, and continue to shape, Canada’s natural landscape. • Geological processes (plate tectonics, earthquakes) Steps to Success Our plan is to learn… • …what physical geography is • … the different ways Canada’s regions can be divided I have succeeded because I… • … can name some components of physical geography • … understand Canada has many different climatic regions, physical regions, vegetation regions and ecozones • …understand why ecozones exist • …can recall some important features of ecozones in Canada Physical Geography is… • ….the study of the Earth’s natural features • 地球的自然特征研究 It includes: • Climate • 气候 • Landforms • 地貌 • Soil & Vegetation • 土壤和植被 • Ecozones • 生态区 Which ones are ecozones? You can divide Canada based on areas with similar features…. 您可以根据具有 类似的功能区域 划分加拿大 Canada N Climate Regions Nunavut British Columbia Quebec Manitoba Alberta Ontario Arctic Boreal West Coast Prairie Mountain Southeastern Weather vs. Climate • Weather 天气 = day to day measures of temperature, precipitation… • Climate 气候 = long term patterns of temperature and precipitation Canada N Physical Regions Western Cordillera Innuitians Interior Plains Appalachia Canadian Shield Great Lakes St. Lawrence Lowlands Lowlands Yukon Yukon Territory Territory Northwest Whitehorse Territories British British Columbia Columbia Alberta Nunavut 物理区域 Quebec Manitoba Alberta Ontario Physical Regions of Canada 植被区 Canada N Vegetation Regions Yukon Territory Northwest Territories Tundra West Coast Forest Boreal Forest Broad-leaved Forest Grassland Mixed Forest Parkland Cordilleran Vegetation Nunavut Quebec Manitoba Alberta Ontario Vegetation Regions of Canada What is an ecozone? • A place based on characteristics of natural origin (climate, landform, soil and vegetation) • 基于天然来源(气候,地形,土壤和植被)的特性的 地方 加拿 大生 态区 David Suzuki Canadian environmental activist David Suzuki Foundation The Nature of Things Wild Canada ** ACTIVITY ** • You will be given a blank map of Canada • You will be given a variety of maps of Canada • YOUR TASK: • Divide Canada into 5-6 ecozones • Remember, ecozones are areas that share similar features • Justify your division (by writing 2-3 sentences per ecozone to highlight similarities within that ecozone, or other reasons why that region exists as a separate ecozone.) • Use colour. Don’t forget the legend! • TIME: 30-40 minutes Class / Home Work • Read Chapter 15 of your textbook (Canada’s Ecozones, pages 172-179 • Answer questions on page 180-181 • Questions: 1a, 3a, 3c, 3d, 3e, 7 ** TASK ** • Individually or in partners… • Pick one of the ecozones (no duplicates) • Create ... • • • • • A song (or) A piece of art (or) A collage (or) A news report (or) Other (need teacher approval) … representing that ecozone. Your job is to make sure the ecozone is well represented and that your fellow student never forget what your ecozone has and why it’s important. Agenda of Big Ideas • Natural environmental characteristics, such as climate, geology, drainage patterns, and vegetation, define the physical regions of Canada. • Canada’s Ecozones • Geological, climatic, and hydrological processes, phenomena, and events have shaped, and continue to shape, Canada’s natural landscape. • Geological processes (plate tectonics, earthquakes) • Erosion, Weathering Steps to Success Our plan is to learn… • …what weathering is • …what erosion is • … how climate changes physical landscape I have succeeded because I… • …understand the difference between weathering and erosion • … can explain weathering and erosion to someone else • … can discuss how climate changes physical landscape What does climate influence ? 什么气候的影响? • • • • What influences (affects) climate ? 有什么影响(影响)的气候? • • • • • • • There are 6 factors that affect climate… 有迹象表明,影响气候的六大因素... • Latitude - 纬度 • Ocean Currents - 洋流 A useful acronym to help remember these factors is • Winds and Air Masses -风 LOWER Near Water • Elevation -海拔 • Relief -景观 • Near to Water -靠近水的地方 Factors affecting climate: Latitude 影响气候的因素:纬度 Latitude: gives the location of a place on Earth north or south of the equator • Closer to the Poles = cooler temperature Why ? Therefore, • Temperature decreases as you move north or south of the equator, because since the Earth is curved, the same amount of light (energy, heat) is spread over a larger area, so less energy per square metre. • 当您移动赤道以北或以南,因为既然地球是弯曲的, 光(能源,热)等量分布在更大的面积,每平方米 让更少的能量温度降低。 Factors Affecting Climate: Ocean Currents 洋流 • Ocean Currents: continuous, directed movement of ocean water • Ocean currents affect climate because they influence the temperature of the air coming off the water. Factors Affecting Climate: Winds 风 Air moves from HIGH PRESSURE to LOW PRESSURE (movement = wind) DAY: air above land heats up quicker than air above water NIGHT: air above land cools quicker than air above water Prevailing Winds: Patterns of air movement from high to low pressure In Canada – the WESTERLIES – blow West to East Jet Stream High Speed Air Current How does the Jet Stream work Factors affecting climate: Altitude 高原 • Higher altitude = cooler temperatures • As air rises, it expands and cools Factors Affecting Climate : Relief (Landscape) 景观 Mountains create barriers of precipitation Factors that Affect Climate: Near Water 靠近水的地方 • Close to large body of water = more rain How does Climate Affect Physical Landscape ? • WEATHERING (& erosion) • Weathering Explained 风化和侵蚀 Weathering • Weathering – chemical and physical processes that change the characteristics of rocks on the Earth’s surface • occurs when rocks are exposed to air/water • Rocks are broken down (weathered) into different types of sediments (sand, clay, pebbles, boulders, cobbles..) SEDIMENTS Erosion • Rock/soil/sediment loose in one area and moved to another (via wind / water) • Process by which the surface of the earth is worn away by action of water, glaciers, wind, waves… • https://www.youtube.com/watch?v=p2X4U1mQzoE Wind Erosion Water Erosion Weathering & Erosion Reflect (hand in at end of class) • Answer TWO of the following questions… • Why does it rain so much in Vancouver? • How do ocean current affect climate? • Bodies of water have a moderating effect on land temperatures. How so ? • Answer this question… • Describe the ways climate can the physical landscape. • ESL STUDENTS – write in point form (not full sentences) • 回答下列问题二... • 为什么下雨这么多在温哥华? • 如何洋流影响气候? • 体水对土地的温度调节作用。怎么会这样? • 回答这个问题... • 描述方法的气候可以物理景观。 • ESL学生 - 写在点的形式(而不是完整的句子)
