Conventional Symbols Direction And Bearing SS1 Geography Lesson Note

CONCEPT OF DIRECTION

The direction of one place or object from another is expressed using compass points or cardinal points. There are 4 cardinal points namely: North, South, East and West. But for better accuracy in the measurement of direction, eight cardinal points are used.

These include North, NorthEast, NorthWest, South, 

SouthEast, SouthWest, East and West.                                 

PROCEDURES FOR MEASURING DIRECTION                                                                                                             

(i) Locate the two places involved on the map.

(ii) Place your four cardinal points at the location or places given.

(iii) Use your ruler to join the place you wish to find its direction from the location or reference point.

(iv) The cardinal point on that line or near it is the direction.

BEARING

The location of one place from another is described as its bearing.

Bearing is expressed in degrees using a protractor, measured from North in a clockwise direction.

Procedures for Measuring Bearing

(i) Locate the two places involved on the map.

(ii) Place your four cardinal points at the reference point because you are looking for the bearing of the other town.

(iii) Use your ruler to join the two places.

(iv) Place your protractor on the side of the line and the degree which falls on that line represents the bearing.                     

ASSIGNMENT   

1. The interval between two points on the map is known as  (a) bearing (b) distance (c) grid system (d) cardinal points
2. One of these is not used for measuring distance (a) straight edge of a paper (b) ruler (c) nylon (d) thread
3. The first step in the calculation of straight distance is? (a) locate the places involved on the map (b) use a ruler to measure the distance between the two points or places  (c) relate the distance measured on the map to the scale given and get the ground distance (d) use a thread to get the distance
4. The cardinal interval between North and East is  (a) North-South (b) North  West (c) West  South (d) North  East
5. The cardinal interval between East and South is a. North-South (b) East  South © South-East (d) North–East
6. State the procedures for measuring bearing.
7. 7. Draw the four cardinal points.
