Large boulders and smaller rocks can be carried by a river. When rocks and sediment are displaced, it's called erosion.
When large boulders are carried along by a river, this process is known as "bed load transport." The boulders are moved along the riverbed, typically by the force of the water, and can be rolled, slid, or lifted depending on the flow velocity and the size of the boulders. This phenomenon is a key component of river erosion and sediment transport.
Clay particles are very fine grained and light weight, so easily carried along by flowing water.
Large boulders carried along by a river are known as "cobbles" or "boulder loads," depending on their size. These rocks are transported by the river's current through a process called erosion, where water wears away the surrounding material. As the flow of the river changes, these boulders can be deposited in different locations, contributing to the river's geomorphology and ecosystem. Their movement can shape riverbanks and create habitats for various organisms.
Large boulders and smaller rocks can be carried by a river. When rocks and sediment are displaced, it's called erosion.
Rocks and boulders carried by the water scour the land (in the same way as wire wool scratches metal) and the debris is carried to the river mouth.
sediment
A stream can bounce large pebbles and boulders, along the stream bed. These rocks are called bed load. A stream can carry sand in suspension. These materials, called suspended load, make the river look muddy. The dissolved load is material carried in a solution, which means that the material is dissolved in the water. Sodium and calcium are some of the materials in the dissolved load.
Mature rivers carry large amounts of sediment along their lengths. This helps to shape the land and produce fertile farm lands.
The load in a river can be transported in 4 ways. The first is Traction. It is when rocks and boulders are rolled along the river bed by the force of the water. The second is Saltation this is when stones and pebbles are bounced along the river bed. The third is Suspension this is when fine particles like silt floot along in the water. The last is Solution which is when the material dissolves in the water. These different methods are used depending on the size of the load to be transported and the energy of the river. A river needs little energy to transport a small mineral by solution but lots of energy to transport heavy boulders it by traction.
