Study Notes
Global Areas
- Geography uses terms to describe locations.
- Earth is divided into hemispheres; northern & southern, divided by the equator, and into western & eastern, divided by the Prime Meridian, which runs through Greenwich, England.
- Regions are areas with similar physical and human geography that can affect each other.
- Factors like resource availability, climate, and terrain influence human settlement patterns.
- Similarities in climate and terrain can result in similar natural vegetation and agricultural suitability.
- Cultural characteristics of a region can be influenced by available foods and clothing adapted to the climate.
- Similar ideas and principles can shape behaviors and values within a region.
- Geographical regions often face similar challenges which can result from climate or weather patterns like storms or droughts.
- Countries in a region with similar geological conditions may have similar resources and produce similar goods.
Why Use Maps
- Maps are useful tools for navigation.
- Ordinance Survey (OS) is the mapping agency for the United Kingdom, provide maps of the whole UK.
- OS maps use symbols to represent features like buildings and roads.
- OS maps include a key to explain the symbols used.
- OS maps also indicate terrain through features like hills and valleys.
- Contour lines, typically orange on OS maps, join points of equal elevation.
- Contour lines have numbers to indicate the elevation.
- Closer contour lines indicate steeper terrain.
- Contour lines show the shape of the land and presence mountain ridges.
- The closer contour lines, the steeper the slope.
- V-shaped contour patterns show a valley while circular contour lines indicate a hill.
Grids on Maps
- Maps use grids to create squares: useful for narrowing search areas.
- Grid lines are numbered to help find specific areas.
- Eastings are numbers reading left to right.
- Northings are numbers reading south to north.
- A four-figure grid reference uses two digits each of the easting and northing numbers.
- Remember to always start with the eastings first ("along the corridor and up the stairs").
- To create a four-figure grid reference, combine grid lines and grid numbers.
- Adding extra numbers to the easting and northing, references can be more precise to work out exactly where features are located.
- Features can be found within 100m on a map with the new extra number.
- A grid square divided into tenths uses the first three numbers for the easting and the last three for the northing, including tenths.
