Let us Use the Graticule | Class 6 | Geography | Chapter 2 | Maharashtra State Board
In this video, you will learn how to use a graticule to calculate the location of a place, the extent of a region and the extent of linear features. We will explain what a graticule is, how it works and what its components are. We will also discuss some important parallels and meridians such as Equator, Tropic of Cancer, Tropic of Capricorn, Arctic Circle, Antarctic Circle, North Pole and South Pole. Using a graticule can be a very useful tool when it comes to navigation, geography, and cartography. We will show you how to read and interpret the different markings on a graticule and how to use them to find specific locations on a map. We will also demonstrate how to measure distances and areas using a graticule. Finally, we will wrap up the video with a fun fact and measure the area of the world's smallest country using a graticule. Whether you are a student or just interested in learning more about geography, this video will provide you with a comprehensive guide on how to use a graticule.

C.S. Location of a road can be described by a map as well as by GIS, GPS, etc.
4. 0° East meridian and 180° East meridian.
Ans. Wrong.
C.S. 0° Meridian and 180° meridian.
5. The extent of a road or a river course is described with the help of the latitude of a point in the source and the longitude of a point at the end.
Ans. Wrong.
C.S. The extent of a road or a river course is described with the help of the latitude of a point as well as longitude of a point in the source and the longitude of a point as well as latitude of a point at the end.
6. 8°4’ N parallel to 37°66° N parallel is the correct description of a location.
Ans. Wrong.
C.S. 8°4'N parallel to 37°66 ° N parallel is the incomplete description of a location, as it expresses only a latitudinal spread of a location.
