CUET PG GEOGRAPHY
Introduction
- We use globe to understand the actual structure of Earth which represents our planet in right manner but in very small size as compared to its original size. It represents the size, shape, direction, distance and relation between the continents, oceans and other forms found on our Earth.
- But we cannot use and carry it everywhere. There are certain difficulties related with its use e.g. large size globe is also not able to provide vast information and more over its formation is also quite tough.
- Map provides the solution of above mentioned problems. Map is a visual representation of an area or selected features of Earth, typically on a flat surface with the help of traditional symbols on the scale which is reduced as compared to actual scale because various types of natural and man-made features are located on Earth and their collective representation is not possible on a single map. An attempt in relation to above mentioned situation will make a map purposeless and unintelligible.
- Inspite of this, in present era maps are not only used by army and students of geography. These are also used by Governments, Planners, Industrial, Commerce, Trade Sector etc.
- Physical Maps show natural features like mountains, rivers, and plains.
- Political Maps display boundaries of countries, states, and cities.
- Thematic Maps represent specific data such as population, rainfall, or vegetation.
- Topographic Maps depict elevation and landforms using contour lines.
- Climatic and Economic Maps show patterns of weather and the distribution of resources or industries.
