Answer:
-subtraction
Explanation:
Elevation is the altitude of a place above a reference frame.
To find the difference between the elevation between two or places on a map, we perform a subtraction operation.
The differences in elevation is the subtraction of the two elevation values from one another.
For example if point A on a map is at 60m above sea level and point B is at 100m, the change in elevation is;
Change in elevation = Elevation of B - Elevation of A = 100m - 60m = 40m
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.
