Regions! Chapter #3 What is a Region? Human Regions What is a formal region? A formal region is an area with at least one characteristic that is common throughout the area. Physical Regions Precise Boundaries: Watershed Areas A formal region can be a city like Toronto or Burlington because they are identified by their boundaries but in other cases formal regions can be identified by landmarks such as lakes,mountains or even rivers. What is a functional region? A functional region is an area identified by what occurs within it. A functional region can be a certain campsite because if you have ever gone camping some sites can have running water,and electricity. Usually all serviced sites are grouped together in a camp site,same thing occurs when your in a hotel. Our school is even a functional region because if you live within a certain boundary then you attend the school within that boundary to learn. What is an urban region? An urban region is an area with at least a population of 1000 people that are clustered together in a fairly compact area. An example of an urban region is London England because there is a large amount of people living in that city. Mississauga is also and urban region. There are many urban regions throughout the world. Lets put it the opposite way... what is not an urban region? Italy itself because there are places in Italy that are urban regions. There are also Country sides that have a low population of people in Italy. Regions In order for geographers to better understand the earth's surface they divide it into smaller physical regions and study them closely. Have you ever looked at an atlas and noticed how they have a number of maps for one specific area? They all have different dividing lines and colors that represent different physical features like the plains and mountains and different transition areas. Other maps will illustrate different physical regions including water, soils, climate as well as natural vegetation. Watershed - An area of land that is drained by by a river system. This physical region is separated from other watersheds by the higher elevation of land in between. Watershed regions have more precise and defined boundaries lines that are drawn along the height of land from which river water runs in opposite directions. See in this diagram how one river on the left side of this line of elevated hills runs/flows south to Lake Superior. The river on the right side of the hills runs/flows north. Here the boundary line between these two watersheds would be drawn right along the top of the hills. Watersheds in Ontario are protected by regional conservation authorities. Conservation authorities - A governmental organization that protects and manages all aspects of the environment for the lands around a river system. If you have ever been camping you may have been in a park operated by a regional conservation authority. In our area, it is the Halton Conservation Authority is responsible for Grindstone Creek, Bronte Creek, Sixteen Mile Creek and North Shore - which is made up of 18 smaller creeks. All these rivers and creeks flow into Lake Ontario. Transition zones You may ask your self: Are all boundaries as precise as those for watersheds? The answer is no, most boundaries between physical regions are gradual and difficult to notice by looking at them. This is because in between physical regions are transition zones. Transition zones - is an area of land where there is a gradual change from one physical region to another. An example of a transition zone are the foothills at the base of the Rockie Mountain, which separate the Rockies from the prairies. Natural Vegetation patterns similarly change gradually throughout transition zones. This is due to the change in climate as you go from South to North. In Ontario you can see how the climate change has caused wide bands of different types of natural vegetation from South to North. In south and warmer part of Ontario you find a broadleaf forest Broadleaf forest - Has deciduous trees that lose there leafs in Autumn. Examples: Elm, Maple and Oak trees. Halton Conservation Authority In the north and colder part of Ontario you find coniferous forest. Coniferous forest - Has evergreen trees with needles and drop cones with their seeds inside. Examples: Spruce, Pine and Cedar trees. In between these two types of forests is the transition zone called the Mixed Forest Region which has both deciduous and coniferous trees. In the most northern part of Ontario, north of the coniferous forest is another transition zone gradually leading to the tundra. Tundra - is a physical region having harty plants and shrubs that survive extreme cold winter months and a short summer. Examples: mosses, grasses and low bushes. Ecozones Ecozones - a region identified by several factors including landforms, climate, soil and natural vegetation. The boundaries for ecozones are different from the sharp boundaries of watersheds and the gradual boundaries for natural vegetation zones. The lines drawn by geographers for ecozones on the map are imaginary. Characteristics of the ecozone are strongest in the middle of each zone and get weaker towards the boundary lines. Each ecozone has different physical characteristics and environmental conditions that support the creatures living there. There are a total of 15 ecozones in Canada. Parks Canada has created large national parks in each ecozone allowing conservationists to address environmental protection issues across our country. Ontario has three ecozones: the Hudson Plains, Boreal shield and Mixed Wood Plains. Boreal Shield is the largest ecozone in Canada and stretches right across our province and five other provinces. The Boreal shield has great natural resources like minerals, lumber, fresh water as well as wild life. The beautiful lakes and forest in this ecozone make it a great area for outdoor recreation. Many people enjoy the Algonquin Provincial Park year round which is the largest environmentally protected area in this region. Formal region Formal region urban regions urban regions formal regions Functional regions Formal regions,Functional regions and Urban regions are three very important things to keep in mind when it comes to Human regions. Not an urban region a Urban region A region is a part of the earths surface with similar features throughout its extent. A physical region is based on characteristics on the earth. Regions help make it unlike from the more flat land of the neighbouring prarie region to the east. What ia a region? Back to the Middle East Regions mostly combine both physical and human features, such as mountains and ski resorts in the Rockies. The middle east has strong physical and human features that help set it apart as a region. The middle east is at a “cross roads “ where Africa , Asia and Europe meet. The middle east didn’t have that name until about a century ago. The middle east does have some distinct features. There is even a disaggrement about which countries are in the middle east. That is because there is no clear boundry.
