LESSON 12.5 SkillBuilder: Communicating
What are compound bar graphs? A compound bar graph is a bar or series of bars divided into sections to provide detail of a total figure. These bars can be drawn vertically or horizontally. The height or length of each section represents a percentage, with the total length of the bar representing 100 per cent.
LESSON 12.6 SkillBuilder: Reading contour lines on a map
What are contour lines? Contour lines drawn on a map join all places of the same elevation (height). These lines are usually brown and have a number written on them to indicate height above sea level. Contour maps are used to show the relief (shape) of the land and the heights of the landscape. Land heights are identified from aerial photography. Natural features, such as rivers, lakes and beaches, and human features, such as towns, roads and power lines, are added to the map to complete the landscape picture. Symbols provided in a legend (or key) or labels on the map add information to complete the image of the environment.
LESSON 12.7 SkillBuilder: Recognising land features
What are land features? Land features are landforms with distinct shapes, such as hills, valleys and mountains. You recognise these as you look around your natural environment. On topographic maps you recognise land features from the patterns formed by the contour lines.
LESSON 12.8 SkillBuilder: Using latitude and longitude
What are latitude and longitude? Latitude and longitude are imaginary grid lines encircling the Earth. They can be drawn over a map to help us locate a place.
