5 Themes of geography Unit 1 World Geography What are the five themes? Tools geographer’s use to study features on earth. •Location •Place •Movement •Region •Human Environment Interaction What is geography? The study of spatial variation How – and why – things differ from place to place on the surface of the earth The study of how observable spatial patterns evolved through time Geography is a spatial science Spatial behavior of people Spatial relationships between places Spatial processes that create or maintain those behaviors and relationships O O Location: Describes where places are at on earth. ABSOLUTE: • exact location on earth (fixed) Doesn’t change • Latitude/Longi tude • Hemispheres • Grid System • Address RELATIVE: • compared to other places (variable) Changes dependent upon where you’re comparing it to. • Miles • Distance • Direction Imaginary lines running east and west around the globe Measured in degrees north and south of the equator. Latitude lines are called parallels because each line is parallel to the next Degrees are units of measurement for latitude and longitude. The symbol for degrees is °. The equator is the imaginary line that circles the Earth’s center known as 0° latitude. Check out the globe! North of the equator EQUATOR South of the equator Parallels above the equator are in the Northern Hemisphere, all below are in the Southern Hemisphere You must write latitude coordinates like this: ˚ ˚ Distance measured in degrees east and west of the prime meridian. Longitude lines are called meridians. The prime meridian is the starting point for measuring longitude. The prime meridian is 0 longitude which goes through the space observatory in Greenwich, England. Check out the Globe! Meridians west of the prime meridian are in the western hemisphere, all in the east of the prime meridian are in the eastern hemisphere. You must write longitude coordinates like this: ˚ ˚ HEMISPHERES O O Five Themes of Geography: Place Geographers study this geography theme by looking at the characteristics that distinguish one place from another place on Earth. PLACE What is it like there, what kind of place is it? Human Physical Characteristics Characteristics What are the main languages, customs, and beliefs. How many people live, work, and visit a place. Landforms (mountains, rivers, etc.), climate, vegitation, wildlife, soil, etc. Theme 2: People Human Characteristics People Culture Buildings and Landmarks Cities People IDENTITY Identity is defined as “the set of behavioral or personal characteristics by which an individual is recognizable as a member of a group.” (American Heritage 2002) NATION Nation - latin verb nasci,meaning to “be born” group of people who share real or imagined common history, culture, language or ethnic origin PEOPLE Cont’d RACE The categorization of humans into groups based on various sets of hereditary characteristics (skin color, cranial and facial characteristics, hair texture etc.) Race does not exist on a scientific level ETHNICITY From Greek word “ethnos” meaning “people, multitude, nation” Ethnic Identity is the sense of belonging to an Ethnic Group Ethnic Groups - Group w/ common ancestry, shared history, culturally symbolic element Culture Language Literature Music What is culture made up of? Architecture It is a groups way of life and its own view of itself and other groups Food Art Religion Buildings and Landmarks Cities Landforms Landforms are naturally formed features on the surface of the earth The sea floor has landforms similar to those above water. Volcano Islands Islands dot the ocean surface. Islands can be formed by volcanic action, deposits of sand, or deposits of coral skeletons An opening in the earth, usually raised, through which gases and lava escape from the earth’s interior Swamp A lowland region that is seasonally flooded with water Marsh Soft, wet, lowlying, grassy land that serves as a transition between water and land Floodplain Flat land near the edges of rivers formed by mud and silt deposited by floods Delta A triangular area of land formed from deposits at the mouth of a river Mesa Wide flat topped mountain with steep sides Plateau A broad flat area of land higher than the surrounding land Butte Raised, flat area of land with steep cliffs (smaller than a Mesa) Prairie A large level area of grassland, very few or no trees Mountain Natural elevation of the earth’s surface with steep sides, to be classified as a true mountain it must be over 1000 feet Glacier A large ice mass that moves slowly down a mountain over land Valley Low land between steep rolling hills or mountains. Canyon A narrow deep valley with very steep sides Peninsula A point of land extending into an ocean or lake Isthmus An isthmus is a narrow strip of land connecting two larger land areas usually with water forms on either side PLACE:Water any significant accumulation of water. Some bodies of water are man-made (artificial), but most are naturally occurring geographical features. Bodies of water that are navigable are known as waterways. Place: Bodies of Water GULF • a large bay that is an arm of an ocean or sea Gulf of Mexico Persian Gulf Gulf of California OCEAN • a major body of saline water Atlantic Arctic Pacific Indian Southern (new addition) RIVER Place: Bodies of Water • A natural watercourse, usually freshwater, flowing towards an ocean, a lake, a sea, or another river TRIBUTARY • a stream or river that flows into a main stem river or a lake. • A tributary does not flow directly into a sea or ocean Place: Bodies of Water LAKE • a body of relatively still, fresh or salt water of considerable size • surrounded by land. • inland and not part of the ocean, HARBOR • a place where ships, boats, and barges can seek shelter from stormy weather, or else are stored for future use. • Harbors can be natural or artificial. Place: Bodies of Water RIVER MOUTH • a part of a stream where it pours into another stream, river, lake, res ervoir, sea, or ocean SOUND • a large sea or ocean inlet • it may identify a narrow sea or ocean channel between two bodies of land Place: Bodies of Water STRAIT • narrow, navigable channel of water that connects two larger navigable bodies of water. SOURCE • the place from which the water in the river or stream originates. Glacier melt Underground streams Lakes (other large bodies of water) Place: Bodies of Water BAY • area of water mostly surrounded by land. • generally have calmer waters than the surrounding sea, due to the surrounding land blocking some waves and often reducing winds. LAGOON • a body of shallow sea water or brackish water separated from the sea by some form of barrier Place: Bodies of Water BAYOU • body of water typically found in flat, low-lying areas, and can refer either to an extremely slowmoving stream or river ESTUARY a partly enclosed coastal body of water with one or more rivers or streams flowing into it, and with a free connection to the open sea. Place: Bodies of Water RESERVOIR • artificial lake is used to store water. • Reservoirs may be created in river valleys by the construction of a dam CANAL • man-made channels for water. Themes of Geography Regions What is a Region? Concept that is used to identify and organize areas of Earth’s surface for various purposes. Has certain characteristics that give it a measure of cohesiveness and distinctiveness that set it apart from other regions. As worlds within worlds, can be used to simplify the whole by organizing Earth’s surface on the basis of the presence or absence of selected physical and human characteristics. Types of regions Formal, Functional and Perceptual. FORMAL PERCEPTUAL FUNCTIONAL designated by official boundaries, such as cities, states, counties, and countries. place where peoples beliefs exists as part of their cultural identity tied by a central point by transportation or communications systems or by economic or functional associations. Formal Also called homogeneous region. An area within which everyone shares in common one or more characteristics such as language, production of a particular crop or climate Formal regions can be defined by measures of population, per capita income, ethnic background, crop production, population density and distribution, or industrial production, or by mapping physical characteristics such as temperature, rainfall, growing season, and average date of first and last frost. Vernacular Also called perceptual region. perceived regions, such as "The South," "The Midwest," or the "Middle East;" they have no formal boundaries but are understood in our mental maps of the world. tends to reflect the element of people’s mental maps, and, although it may help to impose a personal sense of order and structure on the world, it often does so on the basis of stereotypes that may be inappropriate or incorrect Functional An area organized around a focal point. For example, the newspaper circulation area for a major city area is the functional region of that paper or the viewing area of a tv station A typical functional region is a metropolitan area (MA) as defined by the Bureau of Census. Movement Movement How Do People, Goods, and Ideas Get from One Place to Another? Geographers use three types of distance to analyze movement Types of Movement Linear Distance Time Distance Psychological Distance Examples of movement include America's westward expansion, the Information Revolution, and immigration. Linear Distance How far a person, product, or idea travels Time Distance How long it takes for person, product, idea to travel Psychological Distance Refers to the way people perceive distance Example: unfamiliar places may seem farther away than familiar ones Human Environment interaction How Do People Relate to the Physical World? A relationship exists between people and their environment Human Environment Interaction People use and change the environment to meet their needs People adapt to environmental conditions they cannot change Often, people in similar environments adapt in different ways
