Weathering and erosion. Weathering causes rock to break into smaller particles. When these particles are transported by wind, water, or ice, the jagged edges from fracture are gradually worn down from abrasion with other particles, making the outer surface appear relatively smooth. Sometimes the mere abrasive effects of windblown particles on a rock will smooth the exposed surface, leaving the remainder of the rock jagged.

How are round rocks formed?
Rocks are eroded by waves and wind to form a perfectly round, smooth shape. It may take a very long time.
Why do you find smooth rounded rocks at the sea shore and the rivers?
Sediment carried by the river acts as an abrasive against the rocks on the bottom of the river. Rocks are also continually bounced into each other, which also serves to gradually knock off rough edges, making them smoother and rounder.
Where are round rocks found?
In moving water.
What shape is the grain?
Generally, grains of rocks and minerals can be any shape and is usually dependent on the type of erosion and/or weathering. Type of erosion/weathering|Grain shape None |Angular Water |Round, Smooth Wind |Round, Pitted Glacial |Semi-round to Angular with parallel scratches None |(As formed) Physical |Angular Chemical |(In solution)
What happens to the shape of rocks that are transported in streams?
When the rock moves down the river, it causes erosion which then leads to the rock crashing into other rocks, causing it to grind it down to a smaller piece.
What single erosional agent causes rocks to become round?
Water, by attrition.

What caused the Appalachian mountain to become round?
Erosion after millions of years have caused the jagged edges to smooth out.

No.
What two words that describe a sphere?

How do rocks differ in shape?
Rocks differ in shape. The shape of rocks depend on the shape of the minerals that compose them. Rocks may be round or angular.
