Although the light year is a
commonly used unit, astronomers
prefer a different unit called the parsec (pc). A parsec, equal to 3.26
light years, is defined as the distance at which 1 Astronomical Unit subtends an
angle of 1 second of arc (1/3600 of a degree) When we use the parsec for really
large distances, we often put a prefix in front of it - like kiloparsecs (kpc),
which are equal to 1000 parsecs - or Megaparsecs (Mpc), equal to a million
parsecs.
The Milky Way is about 1,000,000,000,000,000,000 km
(about 100,000 light years or about 30 kpc) across. The Sun does not lie near
the center of our Galaxy. It lies about 8 kpc from the center on what is known
as the Sagittarius arm of the Milky Way.
Answer:
4. Ultraviolet radiation breaks apart molecules made up of paired oxygen atoms. Individual oxygen atoms bond with paired oxygen molecules to form ozone
Explanation:
Ozone formation in the stratosphere -
The ozone is the stratosphere layer is former naturally by the chemical reaction , with the help of the ultraviolet radiation of the sun and the oxygen molecules .
In the very first step , The UV radiation breaks the oxygen molecule to give two very reactive oxygen atoms .
In the second step , the atoms of oxygen reacts with the oxygen molecules to produce the ozone molecule (O₃) .
