River rocks tend to be smooth and round because of a combination of the geologic processes of erosion and weathering. Rocks are eroded from surrounding areas and are initially rough and jagged, but over many years they are weathered via transport-induced abrasion to become smooth and rounded.
Apr 30, 2021 · Physical forces like wind, water, ice, and gravity move rocks and smash and bump them against each other. Just like a rock tumbler, the rocks lose their jagged edges and then abrasion rounds out all the points that stick out or protrude as they tumble down mountains and through rivers.
Aug 8, 2019 · Weathering, or the wearing-away of rock by exposure to the elements, not only creates smooth rocks as well as caves and canyons, but it also slowly eats away at other hard objects, including some...
Feb 12, 2014 · Transport of pebbles in a stream causes them to collide and rub against one another and the stream bed, and the resulting abrasion produces the familiar smooth and rounded shape of river rocks.

Abrasion makes rocks with sharp or jagged edges smooth and round. If you have ever collected beach glass or cobbles from a stream, you have witnessed the work of abrasion. Now that you know what mechanical weathering is, can you think of other ways it could happen?

Aug 21, 2015 · A new model suggests that abrasion plays a key role in upholding these patterns, but it does so in a distinctive, two-phase process. First, abrasion makes a rock round. Then, only when the rock is smooth, does abrasion act to make it smaller in diameter.
