What processes create a rounded and smooth rock?
== == 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. Rounded and smoothed stones, if rounded and smoothed on all sides, are usually the product of tumbling. Tumbling is usually accomplished by transportation of the stone by water and contact with other rocks. == ==
What causes the difference between breccias and conglomerante?
The difference between breccias and conglomerate is that breccias are angular and conglomerates are smooth. What causes rocks to be smooth is transportation, such as when rocks are in a stream and are worn down. Therefore transportation is what causes the difference between breccias and conglomerates.
What causes rocks in a stream to be smooth is it weathering?
Rocks in a stream become smooth through a process called abrasion, where the sediments carried by the water wear down the rocks over time. This continuous rubbing and grinding against each other in the stream smoothens the surface of the rocks.
Why does rock tend to become rounded?
Rocks tend to become rounded due to the processes of erosion and weathering. As rocks are exposed to elements like water, wind, and ice, they gradually break down and wear away, causing their edges and corners to smoothen over time. This results in a more rounded shape for the rock.
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.
What causes rocks on the beach to be smooth?
By weathering. The water currents weather the rocks leaving them smooth.
What were the smooth rounded rocks that helped dinosaurs digest and grind their food?
Gastroliths were the smooth, rounded rocks that dinosaurs ingested to help them digest and grind their food. These rocks were swallowed and moved around in the stomach to break down tough plant material.
Where can rocks that have become smooth and rounded be founded?
Rocks that have become smooth and rounded can typically be found in riverbeds, beaches, and coastal areas where the continuous action of water and wave movement wears away sharp edges. These processes, known as erosion and abrasion, gradually shape the rocks over time. Additionally, smooth and rounded rocks can also be found in glacial deposits, where they have been polished by the movement of ice.
When water moves on top of rocks what do the rocks become?
Erosion causes them to become smooth from wear.
Compare the histories of rounded smooth rocks and angular uneven rocks?
Rounded smooth rocks typically originate from processes like erosion and river transport, where water gradually shapes them over time, resulting in their smooth appearance. In contrast, angular uneven rocks are often formed through geological processes such as volcanic activity or fracturing, which leave them with sharp edges and irregular shapes. The history of rounded rocks is often linked to their journey through water, while angular rocks often reflect their origins in solid geological formations. Both types of rocks tell unique stories about their formation and the environmental conditions they experienced.

What causes sharp sharp rough mountains to become rounded and smooth?
erosion -help i helped a lot :)
What happens to the Shape of rocks after abrasion?
After abrasion, such as being tumbled in a stream, the shape of rocks becomes smoother and more rounded. Continued abrasion can wear down sharp edges and angles, creating more rounded and polished surfaces on the rocks.
Why are pebbles smooth and rounded?
Pebbles are smooth and rounded due to the process of erosion, where water, wind, or ice gradually wear away the rough edges and surfaces of rocks over time. As they are transported by rivers or along shorelines, they collide with other rocks and sediments, further smoothing their surfaces. This continuous abrasion leads to the characteristic rounded shape of pebbles, making them more aesthetically pleasing and easier to handle.
Why are rocks found at the bottom of a river are smooth and flat?
Rocks at the bottom of a river are smooth and flat due to the constant erosion and abrasion caused by the flowing water. As water moves over the rocks, it carries sediment and debris that collide with the rocks, gradually wearing down their rough edges and surfaces. Over time, this process results in the rocks becoming rounded and flattened. Additionally, the continuous movement of the water helps to sort and polish the rocks, enhancing their smooth texture.
What agents cause river rocks to be smooth and rounded?
River rocks become smooth and rounded primarily due to the processes of erosion and abrasion. As rocks are transported by the flowing water, they collide with each other and with the riverbed, leading to the gradual wearing away of their sharp edges and surfaces. The continuous flow of water enhances this process, allowing the rocks to become more polished over time. Additionally, sediment carried along by the water contributes to the smoothing effect.
