The earth takes
two types of movements at the same time. 1) Rotation 2) Revolution.
Rotation (محوری گردش): The earth
moves around its axis. This is called rotation.
The movement is
from west to east, speed 1700 km/h.
The Earth is
inclined at an angle of 23.50 at its axis.
Revolution (سالانہ گردش):The movement of
Earth in its orbit around the Sun is called revolution.
Speed of this movement about 107,000 km/h.
Orbit of the
Earth around the Sun is oval shaped.
Solar Eclipse:Some time the Moon comes between the Sun
and the earth and casts its shadow on the earth, due to which the Sun
is not seen completely or partially from the earth, this is called solar Eclipse.
Lunar Eclipse:Some time the Earth
comes between the Sun and the Moon and casts
its shadow on the moon, due to which the moon is not seen
completely or partially from the earth. This is called lunar Eclipse.
Continents and
Oceans:The area of the Earth is about 510 million sq.km out
of which about 29% is comprised of land and 71%
is covered by water.
Continents (براعظم):The land
portion is comprised of seven large masses, which are called continents.
There are seven continents in the worlds.
1) Asia
Continents (براعظم ایشیا ): It is the largest
continent. 2) Africa Continents (براعظم آفریقہ):It is the second
largest continents. 3) North America Continents (براعظم شمالی امریکہ): It is the third
largest continent. 4) South
America Continents (براعظم جنوبی امریکہ):It is the fourth
largest continents. 5) Antarctica
Continents (براعظم انٹارکٹیکا):It is the fifth
largest continent. 6) Europe
Continents (براعظم یورپ):It is the sixth
largest continent. 7) Australia
Continents (براعظم آسٹریلیا):It is the smallest
continent. Ocean (بحر):A huge mass of water is called ocean. There are five
oceans in the world. 1) Pacific
Ocean (بحر
الکاہل): It is the largest ocean. 2) Atlantic
Ocean (بحر
اوقیانوس): It is the second largest ocean. 3) Indian Ocean
(بحر
ہند): It is the third largest ocean. 4)
Southern Ocean (بحرمنجمد جنوبی): It is the fourth
largest ocean. 5) Northern Ocean (بحر منجمد شمالی): It
is the smallest ocean.
