Its because of which type they are further more which year were they made, just like a 'quartzite' its very rare in China and Japan and near countries, rocks may be real or fake, fake ones just break when you drop then 6 ft high, real ones don't break unless by a very stong machine, thats how patterns are created, the first rock was created in 1051, more clearry is created by a change of weather, its its sunny, very sunny, and its starts raining it will create a crackle effect, Google other types of effects to know how they are created...
Scientists date sea-floor rocks by looking at patterns in the rocks, including magnetic patterns, and by looking at the geomagnetic reversal time scale.
looking at patterns
Sedimentary rock is formed when many rocks are broken into small pieces by erosion, after a long time the small rocks fuse together and become a rock with many different layers.
the sun transports its heat and then small snails slither onto them and the sun just flashes at the snail and the snail creates patterns

Nothing they are just random patterns
In order to foliate, rocks must have pressure along one axis and contain minerals with specific growth patterns
By, Looking at the rocks and its different patterns to see where the stars or planets are located and you can probably use its different patterns as a compass.
The earths magnetic polarity at the time of rock formation.
Learning to identify rocks can be difficult when you are first started. Once you get the hang of it though you will start to notice patterns and similarities that will help you to identify rocks and minerals. A good way to start is by purchasing a book about rocks and minerals as well as doing some research on the web.
The geomagnetic reversal time scale has patterns of polarity. It is the pattern of alternating and reserved polarity in rocks.
During physical weathering the elements cause changes in rocks. Water freezes and expands to form linear cracks. This is known as frost wedging. Heat from a fire causes rocks to splinter, and ocean waves batter rocks on the shoreline. Wind carries sand and other small particles that etch patterns on soft rocks.
