                If A = 1, B = 2, C = 3 and so on, what does the code  7   12   15

                  2   5  stand for?




        We have already learnt that the shape of the                                             North Pole 90° N

        Earth is like a sphere. The Earth has landmasses

        and water bodies. The large landmasses are
        called  continents. The continents have been
        divided into countries. We live in a city or a

        village in one or the other country. These cities

        or villages have definite locations on the globe
        or on the map.

        We can locate a place in a city or a village by

        using its address. The address generally includes                       South Pole 90° S
        the house number, the name of the street or                              Axis and Poles of the Earth

        road, and the name of the city and state. In
        early times, we did not have the address system for locating cities or

        villages. Maps only showed the names of thousands of places. We want
        to locate them exactly.


        Since the Earth is like a sphere, it does not have a top or bottom or side
        that can be used as a starting point. The Earth rotates around its axis.

        The endpoints of  the axis are fixed. These two endpoints can be used as
        starting points on the Earth or on the globe. These endpoints are named

        as  North Pole and  South Pole.
