2. ► Scientists believe that about a hundred billion years ago the earth, the
sun, and all the planets of the solar system were nothing only a cloud
of cold dust particles through the empty space.
► Little by little, these particles were attracted to each other and came
together to form a huge spinning disk (a galaxy). As he turned, the disc
in separate rings, and the movement made furious red-hot particles.
► The centre of the disk became the sun, and the particles in the outer
rings turned into large fiery balls of gas and molten-liquid. Then they
began to cool and condense and take on solid form. And at last, some
four or five billion years ago , they became Earth, Mars, Venus and the
other planets.
► The Earth has 4700-7500 millions years.
► The planet Earth is the 3rd planet in the Solar System from Sun.
► It has a satellite that is called ‘‘Moon’’.

3. MERCURY
► Mercury is the planet of the solar system
closest to the Sun and the smallest. It is part
of the so-called rocky inner planets or
satellites lacks.

4. VENUS

terms of size, from smallest to largest. It is
named in honor of Venus,

► The Earth is a planet in the solar system
that revolves around its star in the third

appearance that gives the dominating iron

of all the other planets in the Solar System
combined.

9. SATURN

Zeus.

11. NEPTUNE
► Neptune is the eighth planet from the Sun
and the solar system's farthest. It is part of
the so-called outer planets or gas giants,
and is the first to be discovered through
mathematical predictions.

12. ►Isa round object moving
around a star (Sun)

13. ► The movements: The Earth
rotates eastward.
► The rotation of the planet
earth: Tour for 23 hours, 56
minutes and 4 seconds.
► The trastation of the planet

15. The volcanoes are monticules of rock created by the
collision of the tectonic plaques and this monticules
expulse magma that is the fire of the centre of the Earth.
The common definition of matter is anything that has both mass and
volume (occupies space).For example,
a car would be said to be made of matter, as it
occupies space, and has mass. The main matter are:
-Metal
-Water
-Gassis
