THE SKY

3. The Earth – A Marvelous Planet!

4. ➢About 71% of the earth's surface is covered by water and 29% by
land
➢The earth is surrounded by the atmosphere
➢Atmosphere has oxygen which is essential for respiration of
organisms, nitrogen and carbon dioxide which is essential for the
preparation of food and nutrition of plants.

5. Mercury
✓ It is the nearest planet to the
Sun.
✓ It has no water and is the
hottest planet
✓ So, it has dry climatic
conditions. It has a rocky
surface, large craters and
mountains
✓ It revolves around the Sun
faster than any other planet. It
is brown in color

6. Venus
▪ It is the second planet
from the Sun and smaller
than the earth
▪ It is the brightest planet
in the solar system
▪ It is also known as morning
star, silver star and
evening star

7. Mars
❖It is the fourth planet from the
Sun and is also known as the Red
planet
❖Its red soil is formed because of
iron oxide
❖It has huge volcanic craters,
giant canyons and canals
❖The canals are now as dry as
dust. Thus, it looks like a desert

8. Jupiter
❑ It is the fifth planet from the
Sun and the largest planet in the
solar system
❑ It is 100 times bigger than the
earth
❑ It is a gaseous (gas) giant planet
❑ It has a Great Red Spot
❑ It is three times the size of the
earth. There are thin icy and
dusty rings around this planet.

9. SATURN
o It is the sixth planet from
the Sun and the second
largest planet in the solar
system after Jupiter
o It is also made up of gases.
o It has thousands of rings of
ice, rocks and dust.
o That is why it looks
beautiful and attractive.

10. Uranus
▪ It is the seventh planet
from the sun.
▪ Like Jupiter and Saturn, it
is made up of gases.
▪ It is seen as a blue-green
disc.
▪ It has rings, which are
opaque. It is covered by
thick clouds.

11. Neptune
•It is the eighth planet from the
sun.
•Its composition is like that of
Uranus.
•Its color is bright blue.
•It is one of the coldest planet in
the solar system due to its great
distance from the sun.

12. Meteoroids
➢Small fragments of rocks and debris in space are called meteoroids.
➢When they enter the earth's atmosphere, they burn up in the
atmosphere due to friction and a streak of light is produced.
➢They are known as shooting stars.

13. Asteroids
➢Small rocky celestial bodies
revolving around the sun are
called asteroids
➢Most of them are located
between the orbits of Mars
and Jupiter

14. COMETS
➢ Comet is an icy body that gives out gas
or dust
➢ They revolve around the sun. They can
be seen in the night, when they come
close to the earth
➢ When they come close to the sun, they
produce a long tail which is made up of
gas and dust. Some comets appear at
regular intervals
➢ Halley's comet appears once in 76
years

15. The Earth's Satellite - The Moon
➢A celestial body revolving
around the planet is called a
Satellite
➢The Moon is the only natural
satellite of the Earth
➢It revolves around the earth.
It does not have light of its
own
➢It reflects the light from
the sun during the night

16. Movements Of Moon
The Moon has two movements. One is
rotation on its axis and the other is
revolution around the earth.
As the moon revolves around the
earth, its position in relation to the
sun changes from night to night.

17. ✓ As a result, we can see the
Phases of the moon. The
changes in the moon's visible
face is known as phases of the
moon.
✓ When the moon is completely
dark, we call it New moon
✓ When we see its bright side
totally, we call it Full moon
