Maps and Globe
The GLOBE is a model of the Earth on a small scale.
Details like small towns and villages of a country cannot be shown on a GLOBE.
The Earth’s surface either whole or part of it can be represented on paper. Such representation is called a map.
Since on maps the curved surface of the Earth is represented on a flat surface, the shapes and sizes of the continents gets distorted, specially around the poles.
MAPS ARE OF DIFFERENT KINDS
The Science of Map making is called Cartography.
IMPORTANT FEATURES OF MAPS
Different Maps use different Scales.
The scale of a map is generally shown by a graduated straight line of a particular length
The scale is generally drawn at the top or the bottom of the MAP
Sometimes the scale is not drawn. It is given in words.
For Example: 1cm to 100 km
The size of a map depends on the scale you choose
A Vertical line with an arrow at the uppermost point of this line, found at the upper right or left corner of any map is called the NORTH LINE and it shows the NORTH DIRECTION.
CARDINAL AND INTERMEDIATE DIRECTIONS
People all over the world use the same set of symbols and there is an agreement on these symbols.
These are called Conventional Symbols.
