C.) Dividing
The Great Dividing Range, running just inland along Australia's eastern coast, is that continent's only significant mountain chain.
The similarity is that in every weather there is a season.
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.
<span>On earth, the four major spheres interact as a system.
Atmosphere, biosphere, hydrosphere are absent.
Carbon, Oxygen cycle.
water circuit
tsunami (there is no water so no tsunami)
absence of life
there is no atmosphere so all meteorites directly interact with moon surface. On Earth they can be burn into the atmosphere due to the friction process</span>
