Parallax is used to determine how far a star is from earth by measuring its parallactic angle. If star a has a larger parallactic angle than star b, star a is closer than star b.
<h3>What is parallax?</h3>
When there is a difference in the direction of a celestial object as seen by an observer from two points which are widely separated, then this distance is termed as parallax.
This parallax measurement is used to find the distance of the body from Earth which is called Geocentric parallax and from the Sun which is called Heliocentric Parallax.

Explanation:
Shale is a sedimentary rock that is often associated with oil deposits. This is due in part to the tiny and very fine grains that make up shale. As the sediments are compacted, organic matter is trapped by the particles of clay and silt.
Later, as sedimentation continues and the layers are buried farther underground, the heat and pressure convert some of the organic material into oil. While much of the gas escapes the porous shales, some also remains trapped in the rock layer.
