•   Note the position of the globe.
                       •   Now rotate or spin the globe in a direction opposite to
                           the direction of the hands of a clock (anticlockwise).

                       You will see that the side of the globe facing the torch is in
                       the light (day time), whereas the other side is in the darkness
                       (night time). Here torch acts as the sun. As you spin the
                       globe, the dark side emerges towards the light and thus,
                       experiences the day.
                       In the same way, the rotation of earth on its axis causes the formation of day and night.




                    Eclipse

                    An eclipse is the partial or total blocking of the light of the sun by a heavenly body like

                    the earth or the moon. We already know that the earth revolves around the sun. Similarly,
                    the moon revolves around the earth. At times, all three of them come in a straight line.
                    In such a situation, the light of the sun is blocked by the body in the middle. Thus, it

                    casts its shadow on the third body. The third body is said to be eclipsed or hidden from
                    the sun. Depending on the third body which gets eclipsed by the shadow of the middle
                    heavenly body, eclipse is categorised into two types—solar eclipse and lunar eclipse.


                    Solar eclipse

                    When the sun, the moon and the earth are in a straight
                                                                                                 Did You Know!
                    line in the same order, then the moon blocks the sunlight
                                                                                                Looking at the solar
                    reaching the earth and casts its shadow on the earth. This                eclipse without eclipse

                    is called a solar eclipse. When the moon completely hides                glasses or with the naked
                                                                                              eyes may cause harm to
                    the sun, it is a total solar eclipse. When it hides the sun only
                                                                                                     your eyes.
                    partially, it is a partial solar eclipse. A solar eclipse lasts for

                    only a few minutes.
