Because it is a cycle
yes it has a beginning but it has a end too because it starts all over again but it keeps on going No it doesn't have an ending or a beginning because it is a series or repeating steps. Even if the rock dies out, it'll change to a new type of rocks, and then repeats over and over again. No ending, no beginning, that's why it's call 'cycle.'

Rock tumbling is when small pebbles are mechanically turned over and over for many hours, in a container of fine abrasive/polishing semi-liquid. The end result is polished pebbles for use in arts and crafts ornaments and jewellery.
Tracks and burrows can end up in the rock and fossil record through a process called fossilization, where sediment fills in the impressions left by the tracks or burrows and hardens into rock over time. This process preserves the shape and structure of the tracks or burrows, allowing scientists to study them and learn more about ancient life and environments.
Ralph Gleason, a rock journalist, said that Altamont was "the end of rock music's innocence."
