What are smooth rocks that have been worn down by water?
Essentially, the only types of rock that can stand up to this type of erosion are igneous and metamorphic rocks. I am not certain there is a technical or scientific term for this type of rock, but the colloquial or "slang" term for them is river rocks.
Why river waters are generally rich in calcium and magnesium ions?
River waters can become rich in calcium and magnesium ions through the weathering of rocks and minerals such as limestone, which contain these ions. As river water flows over and interacts with these rocks, they dissolve and release calcium and magnesium ions into the water. These ions contribute to the hardness of the water.
What are three types of erosion that can affect a river valley?
Three types of erosion that can affect a river valley are hydraulic action, abrasion, and attrition. Hydraulic action refers to the force of moving water eroding the river banks, abrasion is the process of rocks and sediment in the water wearing away the riverbed, and attrition occurs when rocks in the river collide, break down, and become smoother over time.
How does erosion create a river bed?
Erosion happens when water flows over land, picking up and carrying away sediment and rocks. Over time, as the water continually moves these materials, it wears down the ground and creates a channel, eventually forming a river bed. The process of erosion carving out the land can also deepen and widen the river bed over time.
What happens when rivers flow over rocks?
When rivers flow over rocks, they can erode the rocks, creating smooth surfaces or formations like waterfalls. The flowing water can also carry sediment and deposit it downstream, helping shape the landscape over time. Additionally, the rocks can influence the flow of the river, creating rapids or eddies.
What is it called when the party of a river or stream where the water flows swiftly over rocks?
It is known as rapids - a length of the river where rocks break the surface and the water is churned into what is known as white water.
What is the part of the river or stream where the water flows swiftly over the rocks called?
Rapids
What happens to rocks left in a river for extended time?
the rocks get grind ed together over and over by the force of water pushing it and eventually become sand.
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.

How are rapids are formed?
Rapids occur in a shallower part of a river where there is a steep difference in levels. This increases how fast the water flows. Water then hits exposed rocks and creates air bubbles making the water appear white in color.

What are the various sounds water makes as it flows through a river?
Water flowing through a river can make a variety of sounds, such as splashing, gurgling, bubbling, and rushing. These sounds are created by the movement of the water over rocks and obstacles in the river, as well as the force of the current.
What is a personification sentence using the word dance?
the sun danced over the water
What is it called when rocks settle down at the bottom of a river?
When rocks settle down at the bottom of a river, the process is called sedimentation. This occurs when the water's flow slows, allowing particles and sediments, including rocks, to accumulate on the riverbed. Over time, these sediments can build up and form layers, contributing to the river's geological features.
What are the characteristics of a waterfall?
The running water in the river erodes the landscape.When the river tumbles at steep angle over very hard rocks or down a steep valley side it forms a waterfall
