Answers
Answer:
1. Maps use symbols like lines and different colours to show features such as rivers, roads, cities or mountains. ... All these symbols help us to visualise what things on the ground actually look like. Maps also help us to know distances so that we know how far away one thing is from another.
2. Most maps contain an arrow marked with the letter 'N' at the upper right hand corner. This arrow shows the northern direction. ... This is the reason that maps have a north line.
3.Scale on a map is important in order to give the map reader a sense of size. Maps are just about always smaller than what they really represent, and scale is a way of quantifying how much smaller they are.
4. All maps have distortions because it is impossible to represent a three-dimensional objects like the earth accurately on flat maps. Maps with no scale give a poor idea of distances and maps with no legend are frequently confusing to the user.
5. Directions shown on a map because with the help of directions, we can easily locate the places. Maps usually have an arrow marked with the letter 'N' at the upper right hand corner. This arrow depicts the North direction.
6. Conventional symbols are widely accepted signs or sign systems which signify an idea or concept. They represent different features on a map and are not drawn to scale. They are important because: Symbols can be used to depict features like cities, roads and railways.
1. Maps use symbols like to show different rivers , roads , cities or mountains

3. A scale is a ratio between the actual distance on the ground and the distance shown on map it means that 1cmon a map will represent a distance of 10 km
4. Maps are easier to use and to carry around
They can show the Earth's entire surface and a small part and can show even a small locality in great detail
5. Because we can easily locate the places
6. Symbols are useful because in any map we cannot draw the actual shape of different features such as roads , railways , bridges etc.
