Explain how the cobbles and pebbles that were transported by these streams become smooth and rounded in shape?

As the cobbles and pebbles are carried downstream by the stream, they constantly collide with each other and with the streambed, causing abrasion. This abrasion gradually wears away the rough edges and corners of the rocks, resulting in their smooth and rounded appearance. The longer the rocks are transported by the stream, the more worn down they become.

Why rocks are smooth in water?

Rocks become smooth in water due to a process called abrasion, where they are constantly rubbed against each other and other materials, such as sand and sediment, while being transported by flowing water. This continuous friction gradually wears down sharp edges and rough surfaces, resulting in a smoother texture over time. Additionally, the tumbling motion of rocks in streams and rivers further contributes to their polished appearance.


Wind and ice cause what sort of change in rocks?

Wind and ice can cause physical weathering in rocks by breaking them apart through processes like freeze-thaw cycles and abrasion. Over time, this can lead to the formation of cracks, fractures, and eventually the breakdown of rocks into smaller pieces.

Why might you find smooth rocks on a beach?

Smooth rocks on a beach are often the result of continuous erosion caused by water and sand rubbing against the rocks over time. The motion of waves can wear down the rough edges of the rocks, making them smooth.
