    Give reasons for
    *. The big stars seem small in size. النجوم تبدو صغيرة
    Because they are very far from us.
    لانها بعيدة


    *. The Sun is a self-shining body.
    الشمس ذاتية الاضاءة
    Because it radiates heat and light.
    لانها تشع حرارة وضوء


    *. The Sun seems bigger to us than other stars.
    Because the Sun is nearer to us than the other stars.



    **. The Sun is a star, while the Earth is a planet


    Because the Sun is lightning body, while the Earth is a dark body


    *. Planets and moons have some similar characteristics.


    Because both of them are dark space bodies.


    6. Although the Moon lights at the sky, we don’t consider it as a star.
    القمر لا يعتبر نجم

    Because it reflects the sunlight. لانه يعكس ضوء الشمس



    7. Jupiter is a planet. المشترى كوكب
    Because it is a dark body that revolves around the Sun.



    *. Mercury is the nearest planet to the Sun, while Neptune is the farthest one.
    Because Mercury has the smallest orbit, while Neptune has the biggest orbit.
    مسار كبير


    *. Although the Moon is a dark body, we see it shiny.
    القمر يبدو مضىء
    Because it reflects the sunlight falling on its surface.
    لانه يعكس ضوء الشمس

    *. Sequence of day and night. تتابع الليل والنهار
    Due to the rotation of the Earth around its axis.
    لدوران الارض حول محورها


    *.Sequence of
    the four seasons. تتابع فصول السنه
    Due to the rotation of the Earth around the Sun.
    لدوران الاض حول الشمس


    *. The movement of shadow at different times of day.
    Due to the rotation of the Earth
    around its axis once every 24 hours.


    *. The Moon has a clear effect on the Earth.
    Because there is attraction force between the Earth and the Moon that causes the tide and the ebb.



    *. The Moon
    rotates around the Earth in a circular fixed path.
    Due to the attraction
    force between the Earth and the Moon.


    *The Moon appears in different shapes during the lunar month.
    Due to the rotation of the Moon around the
    Earth.



    *. The Moon is more effective than the Sun in forming tide and the ebb phenomenon.
    Because the Moon is nearer to the Earth than the Sun.



    *. Occurrence of the tide and the ebb.
    Due to the attraction force between the Earth and the Moon.



    *. A phenamena of tide and the ebb has great benefits

    Because it has many benefits such as, generating electricity


    *. Oxygen gas is very necessary for life of living organisms.
    Because living organisms need oxygen gas in respiration process.



    *.Although the percentage of carbon dioxide gas in air is very
    small, it is very important
    Because the plant use it in making its food by photosynthesis process.



    *. Lime water turns milky if it is left in air for a long time.


    Because the air contains carbon dioxide gas.


    *. Nitrogen gas is very necessary in the atmosphere.
    Because it reduce the effect of oxygen gas in the combustion process.



    *. Oxygen and carbon dioxide gas are very necessary for green plant
    Because oxygen gas used in respiration process, but it uses carbon dioxide gas for making its food during photosynthesis process.


    *.The presence droplets of water on a glass filled with ice.

    Due to condensation of water vapour in air on the outer surface of the glass.
