Meteor
When the
weather is fine at night , we can see many stars twinkling in the sky . Once in
a while we can see a bright ray of light shooting across the sky and then
disappears in an instant . Some people think that the stars have fallen to the fallen
? Of course not ! The ray of light is a meteor
or a shooting star .
A meteor is meteoroid that burns in a
bright streak due to great friction with the air molecules in the atmosphere .
What is a meteoroid ? A meteoroid is a small piece of rock that floats about in
space . In the Solar System, there are millions of meteoroids that move around
the Sun . Meteoroids move close to the Earth . The force of Earth’s gravity
pulls some meteoroids into the Earth’s atmosphere . Most meteoroids burn up into
ashes in the atmosphere before they can reach the surface of the Earth .
Sometimes some meteoroids that are not burn up completely do reach the surface
of the Earth and these are known as meteorites .
Sometimes
many meteors can be seen falling
from the sky . This is known as a meteor shower .
