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

1. What is the difference between longitude and latitude?
Ans. Longitude and latitude are both geographical coordinates used to locate a point on the earth's surface. Longitude refers to the angle between the Prime Meridian (a north-south line passing through Greenwich, England) and a point on the earth's surface, while latitude refers to the angle between the equator (an east-west line around the earth) and a point on the earth's surface.
2. How do I find my latitude and longitude?
Ans. To find your latitude and longitude, you can use a GPS-enabled device such as a smartphone or a dedicated GPS unit. Alternatively, you can use an online tool or a map that displays coordinates. Many smartphone apps also provide this information.
3. What is the purpose of longitude and latitude?
Ans. Longitude and latitude are used to locate a point on the earth's surface. This information is useful for navigation, cartography, and geography. In addition, longitude and latitude can be used to calculate the distance between two points on the earth's surface and to determine the time difference between two locations.
4. How do longitude and latitude affect climate?
Ans. Longitude and latitude can affect climate in a variety of ways. Latitude plays a major role in determining the amount of sunlight a location receives, which in turn affects temperature and precipitation. Longitude can also affect climate by influencing local weather patterns, such as prevailing winds and ocean currents.
5. How accurate are longitude and latitude measurements?
Ans. The accuracy of longitude and latitude measurements depends on the method used to obtain them. GPS technology is generally very accurate, with a margin of error of a few meters or less. Other methods, such as using maps or estimating coordinates based on landmarks, may have a higher margin of error.
