Exam Tip 3 @ 9:30 AM
For the next 3 chapters, chapters 4-6, you have to take note of the following:Chapter 4:
Know the purpose and a general idea of what each map is.
Know your latitude (horizontal lines, running from 90N to 90S) and longitude (vertical lines, running from 180E to 180w)
For express students, you also need to know what is the international dateline is and how to read the different time zone. A simple method to rememeber is when the question ask you what time is country X is when Country Y is 9am.
1. count the difference in the number of hours between each country by looking at the timechart below (use your textbok page 34 for reference).
2. Minus the hours from 9am if the country X is to the left of country Y and add the hours to 9am if country X is right to country Y.
Chap 5:
Mapwork, something I have repeated countless times.
1. Know the parts of the maps like in page36 and 37 of your textbook.
2. Know how to use the scale, remember that the scale is always in cm, unless otherwise stated and convert the final value to Km.
3. 4 and 6 grid reference, read the easting value (values at the bottom part of the map running from left to right), then the northing value (values at the left side of the map running from bottom to top). 6 grid reference must always be taken with estimation the 3rd and 6th values can only be from 0 to 9. If the 3rd and 6th values is 0, then point will cut across the gridline.
4. Compass direction, if the question ask you to find the compass direction of A from B. READ FROM B!!! THAT MEANS THE POINT OF REFERENCE IS B, NOT A!!!!
5. Bearings, check my previous post.
6. Cross section of landforms, here are a few things for you all to take note:
a. Draw your cross section line first.
b. Draw your contour lines and add the contour values into the cross section box. Remember the bottom part of the box is '0' metres.
c. Draw straight lines down from each contour line to the the respective contour line in the contour box with a ruler.
d. Use freehand and join the points where the lines cross each other and the shape must start from the bottom and the highest point must be slightly higher than the highest contour line.
Chap 6:
There are 3 types of photograpghs: Landscape, aerial and satellite and there are mainly 2 types of human settlements, urban and rural.
Be able to recognise what is human features and physical features. The more buildings there are, the more urban it will be is a good rule of thumb.
Landscape photographs can be splitted in foreground, midground and background. Be able to describe each part with at least one detail. It is unlikely that you will find one with nothing to describe.
That is all for now.
