                     a) Ridges   b)trenches   c)Hemispheres     d)equators

               10  The plane formed by  the axis of earth and orbit is called----------.
                     a)Symmetric plane                         c)Orbital plane
                      b)asymmetric plane                      d)inclined plane

               SUBJECTIVE
               QN                                                                    PG       MRK

               1      Revolution causes day and night.

               2      Earth’s axis is always in ------------ position.               18       1

               3      Why all the portions of Earth don’t get light at the           18       1
                      same time?
               4      Draw a neat and labelled diagram of circle of                  18       3
                      illumination.
               5      Differentiate between rotation and revolution.(Any 3           19       3+2
                      points)What would happen if Earth doesn’t rotate?
