ОоThe first maps were drawn by explorers to help them find their way home and show people where they had been. The maps showed the shape of the land, distances between places and special features such as caves and old trees. Nowadays, maps show the towns and villages, and the roads, railways, rivers and mountains. Symbols are used to show all the different things on a map and there is a key to explain what the symbols stand for.
Over the centuries, people explored most of the Earth and put together the map of the world we use today. Maps of the world or large areas are often either “political” or “physical”. The political map shows territorial borders. The purpose of the physical map is to show features of geography such as mountains, soil type or land use including roads, railroads and buildings.
