The Universe:
It is a wide huge space that has millions of stars. The solar system consists of:
The sun, eight planets, moons and other celestial bodies such as asteroids, meteors, meteoroids and comets.
The sun: It is a shining star radiates light and heat it is the nearest star to us
The stars : they are shining bodies
The planets : they are dark bodies revolve around the sun
*mercury : it is the nearest planet to the sun
*venus : the most beautiful planet
* the earth : the planet which we live
* mars : it is the red planet .
* Jupiter : it is the biggest planet .
*Saturn :has a big number of colored ring .
* Uranus : the cold planet .
* Neptune : the blue planet .
The moon : it is dark body revolves around the earth
Moons : they follow the planets and revolve around some planets
Q1: give reason : the sun is star but the earth
Is planet
- because the sun radiates light but the earth is dark .
2- stars seems very small size
Because they are far away from us .
3- the moon is dark body but we see it shining
- because it reflect the sun light .
The rotation of the sun and earth دوران الشمس والارض
* The Earth consists of two hemispheres
(northern hemisphere and southern hemisphere). نصف الكرة الشمالى والجنوبى
* Egypt lies at the northern hemisphere of Earth.
* The Earth rotates around itselfتدور حول محورها الارض
Rotation of the Earth around itself
* The Earth rotates around its once every24 hours
* The side (hemisphere) of the Earth that faces the Sun
during this rotation becomes bright on day, while its other side
becomes dark on night.
The rotation of the Earth around its axis causes the sequence day and night.تتابع الليل والنهار نتيجة الى دوران الارض حول محورها
The movement of shadow الظل of fixed objects is due to the rotate of Earth around itself
Rotation of the Earth around the Sunدوران الارض حول الشمس
- Earth revolves around the Sun once each 336 and quarter day (year).
* This rotation causes the sequence of the four seasons فصول السنة الاربع
)summer - spring — autumn – winter(
* In summer season, day is longer than night.
*In spring or autumn hours of day is equal hours of night
*The movement of the shadow is a result to the apparent
rotation of the sun. الحركة الظاهرية للشمس
*the sun seems moving from east to west because the earth
rotates around its axis and not to the rotation of the sun..
the earth rotates around its axis once every 24 hours causing day and night
*the hours of day is not equal to the night because the axis of the earth is inclined مائل
