FAQs on NCERT:Globe Latitudes and Longitudes Video Lecture - Geography for UPSC CSE

1. What are latitudes and longitudes?
Ans. Latitudes and longitudes are the geographical coordinates that help in determining the exact location of a point on the Earth's surface. Latitudes are imaginary lines that run parallel to the Equator, measuring the distance north or south of it. Longitudes, on the other hand, are imaginary lines that run from the North Pole to the South Pole, measuring the distance east or west of the Prime Meridian.
2. How do latitudes and longitudes help in locating places on a globe?
Ans. Latitudes and longitudes provide a reference system that helps in accurately locating any place on the Earth's surface. By using the degrees of latitude and longitude, one can pinpoint the exact position of a place. This information is crucial for navigation, finding destinations, and understanding the spatial relationships between different locations.
3. What is the significance of the Equator and the Prime Meridian in the latitudes and longitudes system?
Ans. The Equator is the starting point for measuring latitudes. It is a circle that divides the Earth into the Northern Hemisphere and the Southern Hemisphere. The Prime Meridian, passing through Greenwich, London, is the starting point for measuring longitudes. It divides the Earth into the Eastern Hemisphere and the Western Hemisphere. These reference lines provide the basis for measuring distances and determining directions on a globe.
4. How are latitudes and longitudes measured?
Ans. Latitudes are measured in degrees, minutes, and seconds. The Equator is assigned a latitude of 0 degrees, and the latitudes increase towards the poles, reaching a maximum of 90 degrees at both the North Pole and the South Pole. Longitudes are also measured in degrees, minutes, and seconds. The Prime Meridian is assigned a longitude of 0 degrees, and the longitudes increase to the east and west, reaching a maximum of 180 degrees.
5. Can latitudes and longitudes be used to determine the exact address of a location?
Ans. Latitudes and longitudes provide a precise location on the Earth's surface, but they do not directly correspond to street addresses or specific locations within cities. While latitudes and longitudes can help in locating a general area, additional information such as street names, house numbers, or landmarks is needed to determine the exact address of a location.
