Pebbles are small, rounded stones that you often find on beaches, riverbanks, and in gardens. They come in various colors, shapes, and sizes, making them beautiful and interesting to collect. Pebbles are formed over time as larger rocks break down due to weathering and erosion, which is a natural process caused by wind, water, and ice. People often use pebbles in landscaping to create pathways or decorate flower beds. They can also be used in art projects or as decorative elements in aquariums. Some even enjoy skipping pebbles across the surface of a lake for fun!
