Explanation:
Glaciers<span> begin to </span>form<span> when snow remains in the same area year-round, where enough snow accumulates to transform into ice. Each year, new layers of snow bury and compress the previous layers. This compression forces the snow to re-crystallize, forming grains similar in size and shape to grains of sugar.</span>

Answer:
It corresponds to a distance of 100 parsecs away from Earth.
Explanation:
The angle due to the change in position of a nearby object against the background stars it is known as parallax.
It is defined in a analytic way as it follows:
![\tan{p} = \frac{1AU}{d}](https://tex.z-dn.net/?f=%5Ctan%7Bp%7D%20%3D%20%5Cfrac%7B1AU%7D%7Bd%7D)
Where d is the distance to the star.
(1)
Equation (1) can be rewritten in terms of d:
(2)
Equation (2) represents the distance in a unit known as parsec (pc).
The parallax angle can be used to find out the distance by means of triangulation. Making a triangle between the nearby star, the Sun and the Earth (as is shown in the image below), knowing that the distance between the Earth and the Sun (150000000 Km), is defined as 1 astronomical unit (1AU).
For the case of (
):
![d(pc) = \frac{1}{0.01}](https://tex.z-dn.net/?f=d%28pc%29%20%3D%20%5Cfrac%7B1%7D%7B0.01%7D)
![d(pc) = 100](https://tex.z-dn.net/?f=d%28pc%29%20%3D%20100)
Hence, it corresponds to a distance of 100 parsecs away from Earth.
<em>Summary:</em>
Notice how a small parallax angle means that the object is farther away.
