Skills for Geography

1. Topographic Maps

   • Area and grid Reference
     • The vertical lines are called eastings
       • This is stated first
     • Horizontial lines are called Northings
     • Area Ref:
       • Uses 4 digits
       • the dot is in the bottom left corner
     • Grid Reference
       • Has 6 numbers
       • the point is somewhere in the square
   • Contour
     • When the lines are closer together it means that there is a slop
     • When the lines are far apart it means that it is a flat area
     • Contour interval: is the value between the contour lines
     • When lines are evenly spaces out then it is a constant slop

2. Reading and interperating climate graphs and weather maps

   • Troughs and ridges
     • A trough occures when an area of low pressure extends between 2 high pressure systems. Often brings rain
     • A ridge occures when a high pressure system is between 2 low pressure systems
     • They are both marked by a dashed line on a synoptic chart

3. Rules for Climate statistic charts

   • Rainfall on the left
     • is a colume graph
   • Temperature on the right
     • Is on a line graph
       • Plat the points in the middle of all the squares
         • Join the Pints together in a smooth line
   • Range
     • To find the range subtract the smallest value from the largest value
   • Annual average rainfall
     • Is the average rainfall for the year
     • Add up all the average mothly rain together
   • To find the annual range
     • Subtract the smallest value from the largest value from the moths
