Transcript of SS Maps and Globes!!

1. Maps are one of the most important tools on Earth. They help us find places. They show us Earth's mountains and oceans. To read a map, you need to understand its different parts. 3. The next important part of the map is the symbols. Maps show a smaller picture of the Earth's surface. You can't draw a life-size mountain on a small piece of paper. That is why cartographers use small pictures. Symbols are the points, lines, and patterns that are listed in the map key. The key is a box located in one of the bottom corners of the map. Symbols have different colors depending on the physical feature the drawing represents. For example, water features like rivers, lakes, and oceans are colored blue. Trees, woods, orchards, and shrubs are usually colored green. Red is used for important roads. What about buildings and mountains? Well, buildings are usually colored black, and mountains and hills are colored brown. 2. Maps are paper diagrams of the Earth's surface. The first part of a map you need to know is its title. The title tells you what the map is showing. A map of the streets in your town would have your town's name as its title. A compass rose helps you to find direction. Although it is not a flower, it is still important. A simple compass rose may look like a plus sign with arrows. At the ends of the arrows the four cardinal directions would be listed. They are north, south, east, and west. The top arrow would point to the top of the map, which is north. The bottom arrow points south to the bottom of the map MAPS!! parts of maps Uses and Purposes of Maps Geological maps show not only the physical surface, but characteristics of the underlying rock, fault lines, and subsurface structures.
A geologic map or geological map is a special-purpose map made to show geological features.
Rock units or geologic strata are shown by color or symbols to indicate where they are exposed at the surface. Geological Map A thematic map is a map that focuses on a particular theme or special topic and they are different from the other maps.
If the map shows natural features like rivers, cities, political subdivisions, elevation and highway, they are background information and are used as reference points to enhance the map's theme. Thematic Map Road Map A road map is one of the most widely used map types for planning trips and driving directions.
These maps show major and minor highways and roads as well as things like airports, city locations and points of interest like parks, campgrounds and monuments.
Major highways on a road map are generally red and larger than other roads, while minor roads are a lighter color and a narrower line. An economic or resource map features the specific type of natural resources or economic activity that dominates an area.
Cartographers use different symbols or colours to show the locations of natural resources or economic activities depending on what is being shown on the map. Economic or Resource Map It gives general information about the climate and precipitation of a region using different colours to show different climatic areas.
They can show things like the specific climatic zones of an area based on the temperature, the amount of snow an area receives or average number of cloudy days. Climate Map A physical map is one that shows the physical landscape features of a place.
They generally show things like mountains, rivers and lakes and water is always shown with blue.
Mountains and elevation changes are usually shown with different colors and shades to show relief. Physical Map Political Map A political map does not show any topographic (physical) features.
It instead indicates the state and national boundaries of a place, capitals and major cities.
It include the locations of cities - both large and small, depending on the detail of the map Types of Maps Topographic maps show elevations and relief with contour lines or shading.
A topographic map uses contour lines instead of colors to show changes in the landscape.
Contour lines on topographic maps are normally spaced at regular intervals to show the shape and elevation changes and when lines are close together the terrain is steep. Topographic Map different projections of maps Thank you for your kind attention! We hope you enjoyed our Prezi ^^ Maps help you to locate a particular place on the Earth and tell you where they are from the place you live. All Maps have the same parts. Each part helps you to read the Map and understand it.
A map is a picture of a place. Different maps show different information. No one map can show you everything. The study of maps is important for many reasons, as maps can help you find different places or certain locations. The map will then tell you many things and give you information about certain locations. They show you places you can visit, like parks, shopping centers, and museums. However, how would you know how to get to the place you want to go? Maps show you in which direction or directions to go to reach the place you wish to visit. Suppose you are visiting Los Angeles, you would use the map to show you which way you should go to get there. Map Title : The Map Title tells you what the map is and is usually found on the top or bottom of the map. Map Scale : Map scale is the relationship or ratio between a linear measurement on a map and the corresponding distance on Earth's surface. Most maps have a distance scale somewhere on it. You can use the distance scale to measure the distance between places. Directions :A map symbol that shows directions. You must have seen the drawing showing East, West, North, and South directions on a map. This drawing is called as the compass rose and it helps you to know the directions. These four directions North, South, East, and West are called as the 'Cardinal Directions'. Map Key : The map key is found on the bottom of the map. The map key tells you what the symbols on the map stand for. Symbols are small pictures on the map used for representing real things on our Earth like mountains, hills, and valleys etc,. Remember, symbols don't always look like what they represent in the real world. These are the parts of a map and what a map tells us. Maps are very important and help many people get from place to place! Counties often started out large and then were divided, sometimes or several times, as populations grew. Your ancestors may have lived on the same farm for two hundred years, but their records could be in five counties because of shifting borders. Maps from specific times will help you find those boundaries. Points of latitude and longitude are imaginary lines created by mapmakers to allow them to pinpoint any place on the globe or map. Nah, not this kind... Compass rose : An object that appears on maps to identify four main directions: North, South, East and West. For example, the scale 1:100 means that one unit (inch or centimeter) on the map and represents 100 similar units on Earth's surface. The term small scale sometimes refers to the study of small areas. A map projection is any of many methods used to represent the 3-dimensional surface of the earth or other round body on a 2-dimensional plane in mapmaking. This process is typically, but not necessarily, a mathematical procedure.

The creation of a map projection involves three steps in which information is lost in each step:
1) Selection of a model for the shape of the earth or round body (choosing between a sphere or ellipsoid)
2) Transform geographic coordinates (longitude and latitude) to plane coordinates
3) Reduce the scale (in manual cartography this step came second, in digital cartography it comes last) GLOBES!! Different Projections of Globes Different Projections of Globes Uses and purposes Used to teach Geography
Emphasizes the physical unity of the world
Shows how one part is related to all the rest
Shows the direction from one part of the Earth to another
useful for amateur astronauts
to find cities, nations, land and water areas easily
as an instrument for peace
illuminates the pages of history
makes events in today's world more significant
enriches our understanding of the sciences including the exciting new sciences of inner and outer space Tania and Xiao Ran! :P Types of globes show political boundaries of Earth
show the topography of Earth
show both of the above
demonstrates the topography of the planet with exaggerated relief of the major physical characteristics; eg. raising the mountains beyond the surface of the sphere, while deep valleys and ocean canyons are depressed
made of metal
made of a sphere covered strips of paper
made using small electromagnets to allow them to hover in the air and rotate on an axis between two magnets
represent other celestial bodies like the Moon or Mars
depict fictional planets
virtual globes mapped in computer programs
star globes which depict the stars from the sky as seen on Earth This one!!! --> Globes Maps and Globes... ...
