Answer.
What is a map?
The map is a visual representation, or a drawing, of some area — it may be a small area (a village, a town, etc.), a bigger area (a district or state), or a very large area ( like India or even the whole world).
The map shows geographic features, political boundaries, roads, and other important details.
There are several kinds of maps-
- Physical Maps (mainly show some natural features such as mountains, oceans, and rivers)
- Political Maps ( mainly show details of countries or states, boundaries, cities, etc.)
- Thematic Maps ( mainly show a specific kind of information like rainfall, earthquake-prone region, flood region, etc)
How do we use a map?
It helps us understand the layout of a place, political boundaries, landforms, water bodies, and the positions of cities and navigate from one location to another.
The following way, we use a map:
- Navigation: ( Maps help us find our way from one place to another )
- Planning: ( Maps help us understand the layout of new areas).
- Education: ( Maps help us to teach geography, history, and environmental science, helping people understand spatial relationships and global contexts )
- Problem-Solving: ( Maps help us in analyzing geographic data for various fields like urban planning, disaster response, and environmental management)
- Recreation: ( Maps are useful for outdoor activities like hiking, biking, and boating, providing information on trails, water bodies, and other features)
Main components of a map:
There are three important components distance, direction, and symbols.
Distance:
The actual distance between two points represented on the map depends on the scale that the map is using.
Direction:
North, East, South, and West are called the cardinal directions. Other than these, intermediate directions are also used - northeast (NE), southeast (SE), southwest (SW) and northwest (NW).
Symbols:
Our map has small drawings of actual buildings and a few other elements, but there would not be enough space on the map of a large city or a country to draw them all. Instead, a symbol is used to represent these features — symbols for different kinds of buildings (for instance a railway station, a school, a post office), for roads and railway lines, and for natural elements such as a river, a pond, or a forest.
