A map is a flat drawing of a place as it would look from the top. Not only can these be drawn on any paper but can be reduced to drawing of a place. They can be a drawing of the whole earth or a part of it kike the United states map. The human brain tends to remember maps better than any written text as we register images faster in our brain than the texts. They are a better tool to explain any geographical location. Places and features of maps are shown by using different symbols. Like roads are shown by a bold black line while railway track is shown with a bold black line having vertical cuts. This way we differentiate different features shown on the maps. A petrol station is shown by a picture of a petrol pump while a restaurant is represented by a spoon and a fork together.
