What else can I help you with?
Rocks being made smooth by tumbling across a stream bed is an example of?
Mechanical weathering, specifically abrasion. The rocks are physically broken down and worn away as they rub against each other and the stream bed, creating smooth, rounded surfaces.
Which causes rocks in a stream to to be smooth?
Rocks in a stream become smooth due to the constant force of flowing water wearing down their rough edges over time. The friction and impact from water flow results in abrasion, breaking off small particles and gradually shaping the rocks into a smoother surface.
What causes rocks to be smooth?
By weathering which is the gradual wearing away of something. In this case rocks can be weathered by water (current in a large water source or heavy rains) and even wind and other things such as acid rain. Hope that clears things up!
Why are some rocks smooth and other are not?
Rocks become smooth through the process of weathering, which includes abrasion from wind, water, or ice over time. Rocks that are not smooth may have experienced less weathering or may be composed of harder materials that resist erosion. The smoothness of a rock can also depend on its location, as rocks in a riverbed or along a coastline are more likely to become smooth.
Which type of weathering causes the mineral composition of rocks to change?
Chemical weathering is the type of weathering that causes the mineral composition of rocks to change. This process occurs when minerals in rocks react with elements in the environment, causing a chemical reaction that alters the rock's mineral composition over time.
What cause rocks in a stream to be smooth?
flowing water
What causes rocks on the beach to be smooth?
By weathering. The water currents weather the rocks leaving them smooth.

How does rocks get smooth?
some from weathering
What causes the breakdown of rocks?
WEATHERING and EROSION

What is the natural process that causes rock to breakdown?
Weathering from mechanical and chemical means is the process that causes rocks to become smaller and smaller; wind, rain, the sun, the freeze/thaw cycle, moving glaciers, chemical reactions, and gravity are some of the causes of weathering.
How do acids in groundwater cause chemical weathering?
It causes chemical weathering because when it touches rocks, the rocks dissolve, forming caves.
Why do the rocks located in stream beds are smooth?
Rocks in stream beds can become smooth due to a process called abrasion. As water flows over the rocks, it carries sediment and particles that constantly rub against the rocks, wearing them down and making them smooth over time. The friction caused by the movement of water and sediment helps polish the surface of the rocks.
