Explanations:Geographical coordinates are a fundamental concept in geography and are used to pinpoint the exact location of a place on Earth. These coordinates are expressed in terms of latitude and longitude. Latitude is the angular distance of a place north or south of the equator, measured in degrees. Longitude is the angular distance of a place east or west of the prime meridian, also measured in degrees.
The equator is the line of latitude that divides the Earth into the Northern and Southern Hemispheres. The prime meridian is the line of longitude that divides the Earth into the Eastern and Western Hemispheres. The equator is designated as 0° latitude, and the prime meridian is designated as 0° longitude. All other latitudes and longitudes are measured relative to these reference lines.
For example, the city of Bangalore is located at 13°N, 78°E. This means that Bangalore is 13 degrees north of the equator and 78 degrees east of the prime meridian. The coordinates of a city are important for various applications, including navigation, mapping, and understanding the geographical layout of a region.
It is important to note that the coordinates of different cities can be quite different. For instance, New Delhi, the capital of India, is located at approximately 28.6139°N, 77.2090°E, which is significantly different from the coordinates of Bangalore. Similarly, Chennai, another major city in India, is located at approximately 13.0827°N, 80.2702°E, and Hyderabad is located at approximately 17.3850°N, 78.4867°E. These differences in coordinates reflect the geographical distribution of cities across the country.
Understanding the geographical coordinates of cities is essential for students preparing for competitive examinations such as the UPSC, SSC, and State PSC, where questions on the geographical layout of India are common. Familiarity with the coordinates of major cities can help in answering such questions accurately and efficiently.
