    10.  The Moon is much smaller than the Sun, yet
                                                                                    (c)   the Sun’s light is weak compared
                         it can completely cover the Sun during a total
                                                                                       to the Moon’s reflection
                         solar eclipse. This is because

                                                  (Abstract Thinking)               (d)   the Earth’s shadow helps the Moon
                                                                                       block the Sun.
                                (a)   the Moon is denser than the Sun

                                (b)   the Moon is closer to Earth, so its
                                   apparent size matches the Sun

                                       Why can lunar eclipses be seen from a large part of Earth, while total solar
                                       eclipses are visible only from a small region?

                                             (a)   The Moon’s shadow is larger than Earth’s shadow.

                                             (b)  Lunar eclipses are brighter and easier to observe.

                                             (c)  Solar eclipses occur at night, so fewer people can see them.

                                             (d)   Earth’s shadow on the Moon covers a wide area, while the Moon’s
                                                 shadow on Earth is narrow.
