Answer:
11) The "general climate of an area" can be described with the aid of the "lines of latitudes" as the temperature decreases north and southwards starting from the equator. Latitudes are "imaginary lines" dividing the earth into two halves namely the "northern and the southern hemispheres".
12. The Greenwich meridian or the Prime Meridian is used to fix the World time.
13. 82 degree 30 minutes East is the longitudinal value of indian standard meridian. 82 degree 30 minutes East is the longitudinal value of indian standard meridian.
14. Great circle route, the shortest course between two points on the surface of a sphere. It lies in a plane that intersects the sphere's centre and was known by mathematicians before the time of Columbus. ... Long-distance air traffic uses great circle routes routinely, saving time and fuel.
1.a) The five major parallels of latitudes from north to south are called: Arctic Circle, Tropic of Cancer, Equator, Tropic of Capricorn, and the Antarctic Circle. On a maps where the orientation of the map is either due north or due south, latitude appears as horizontal lines.
b) The lines of latitude run east and west, parallel to the Equator. They are used to define the North-South position of a location on the planet. Major latitude lines include: Equator which is 0 degrees.
c) i) Lines of latitude are also called parallels because they run horizontally to each other and the equator. They are spaced evenly apart.
ii) The lines of latitude are not all equal in length. It is because they are complete circles that remain equidistant from each other. The lines of latitude vary in size from the longest at the equator to the smallest, which are just single points, at the North and South Poles.
iii) Lines of latitude carve out the heat zones of the earth. The Temperature goes on decreasing from the equator towards the poles. So the latitudinal zones are the actual heat zones of the earth, namely tropical, temperate and polar zones.
