Calculating Time Ok, so we already know the following: - 1 hour is 15° - 1° is 4 minutes - Add 1 hour when moving to the east - Minus 1 hour when moving to the West Here's how to do your calculations Example 1 If a place is 45°E , then it is ahead of Greenwich Meridian. If the time is 12 midday at Greenwich what time will it be at 60°E? Step 1 45°E   = 3 hours ahead of Greenwich 15°E 12 midday plus 3 hours would be 3pm This could also be done using a number line Example 2 If a place is 76°E , then it is ahead of Greenwich Meridian. If the time is 12 midday at Greenwich what time will it be at 60°E? Step 1 76°E   = 5 hours remaining 1 ° 15°E 1 ° equals 4 minutes therefore  76 °E would be 5 hours and 4 minutes ahead of Greenwich 12 midday plus 5 hours and 4 minutes would be 5:04pm Try the Calculating Time Worksheet.

Important Points to Remember - The Earth Rotates from West to  East - Places to the East see the sun first - Imagine the sun at 1 end, that is at the East and the Earth at the West rotating on its axis                                                                                                 Now visualize the lines of Longitude on the Earth. All places on the same line of longitude will see the sun at the same time during the day. When calculating time, we start from 0 degree longitude which is Greenwich Meridian Time (G.M.T) or the Prime Meridian. So places to the East of the 0 degree line will be ahead of time, therefore, you will add time. Likewise, places to the West of the 0 degree line will be behind time, therefore you will minus time. Example: If it is 1pm at 0 degrees, East of the 0 degree line will be past 1pm. so it could be 2pm, 3pm, 4 pm etc. and West of the 0 degree line will be before 1pm, so it could be 12 midday, 11am, 10 am etc. So n

Measuring Straight and Curved Line Distances To measure distances on a map, the scale is needed. (See previous post titled "Types of Scales"). Distance on a map can be measured in two ways:                   - Straight line           - Curved Line STRAIGHT LINE DISTANCES The distance between two places can be measured in a straight line. Straight line Distances can be measured using a ruler,  a strip of paper, a pair of dividers, string or a strip of paper. This is how it is done. Steps 1. Identify the two points 2. Draw a straight line to connect both points 3. Place the straight edge of a piece of paper along the line 4. Mark off the points to be measured 5. Remove the paper 6. Place it along your scale starting at zero (0) 7. Record your answer Measuring Curved Line Distances You may be asked to measure the distance between two points along a curved line such as a road, railway,  coastline or river. To do this, you use a string or straight ed

Scales Define scale Types of Scale Description of each type of Scale A scale is a map element that is used to show the distance on the map in relation to the actual ground. A scale of a map is represented by:-      - A linear scale A linear scale is the most commonly used scale. It is a line divided into equal parts called segments. See example below      - A statement scale A statement scale is given in words.  For example, 1cm represents 1km. It can also be written as 1cm:1km. This means that one centimeter on the map is equivalent to 1 kilometer on the actual ground. Note that two units of measurement are given.       - A representative fraction scale This is written as a fraction or ratio. No unit of measurement is given because if the unit of measurement is centimeters, the scale means that one centimeter on the map represents 100,000 centimeters (1km) on the actual ground. Example 1:100,000     or         1                               100, 000

This post shows some conventional and non-conventional map symbols. Maps show features as birds see it from above.   It is impossible to label every single feature in words on a map, therefore we use map symbols. How to tell what each Map symbol means Every map is accompanied by a legend or key.    The Key tells us what each symbol on the map stands for. Such symbols may be drawings, letters, lines, shortened words or colored areas. Most map symbols are conventional signs as they are understood by everyone around the world. Some conventional map symbols can be seen below. Other map symbols Watch the video below for a quick idea on how to read maps

This post includes: Definition of Map, Map Elements, Types of Map What is a Map? A map is a diagrammatic representation of all or part of the Earth's surface shown from an aerial view. Map Elements The word "element" refer to a central part of something. In map making, map elements refer to the basic parts making up the map. These include: Title Scale Compass Direction Key Border Title This indicates the name of the place being represented. It may also include the type of map. Scale This indicates the size of the map in relation to the actual ground being represented. There are different types of scales. You can learn about them in another post. Compass Direction This is an arrow that indicates where North is on a map Key This shows what the symbols, abbreviations and colors on the map means.   Border This is a square or rectangle drawn around the map as a boundary Here's a song to help you remember the map features

There are five themes of Geography. Watch the introductory video below and listen for the 5 themes. An easy way to remember the 5 themes is by saying  M any P eople H ate R ed L ipstick that is... Movement  Place Human Interaction Region Location

Introduction to Geography This post includes the definition of the word Geography, Branches of Geography, Sub-Branches of Geography, Importance of Geography as well as Careers in Geography. Definition Every Definition of Geography must include 3 things: 1. The People             2. The Earth               3. Interaction between the people and the environment A good definition therefore would be: Geography is the study of the Earth, the People and their interaction with the natural environment. Branches There are 2 main branches of Geography. These are Physical and Human Geography.  In Jamaica, we also include a third branch. This is Quantitative Geography which will be discussed below. The three branches would therefore be: 1. Physical Geography 2. Human Geography 3. Quantitative Geography Physical Geography This is the study of natural features and systems of the Earth. This includes the atmosphere, oceans and landforms among other thing
