The pebbles become smooth and even because of erosion. the waves from the sea rub against the pebbles this is erosion. x

On the seashore, pebbles that are rough and uneven become smooth and rounded due to a natural process called abrasion. As waves pass by, they cause pebbles to collide with each other and with larger rocks, which gradually chips away the sharp edges and corners. This continuous tumbling and striking action results in the pebbles becoming more rounded and smooth.
Different beaches can have sediments like sand, pebbles, or cobbles and these can be rounded to varying degrees. The size, shape, and rounding of sediments on the beach can be a clue to the beach's history of wave activity. Strong wave activity, especially during different seasons, moves these sediments, further smoothing them out.
Rounded grains indicate that they have been subjected to a longer time of erosion, a longer transport distance, or a more energetic erosional process. Mineral hardness also plays a role in how quickly the sediments become rounded. In summary, the smoothing of pebbles on beaches is due to the persistent wearing down and rounding from wave-induced motion and collisions.

Pebbles become smooth and rounded through a process called erosion, primarily due to wave action and abrasion. Waves crash onto the shore, causing pebbles to collide with each other, gradually wearing away their sharp edges. Over time, this leads to smoother, more rounded shapes.
