Erosion in a river wears down the rock's surface over time, smoothing out its edges and shaping it into a rounder form. The constant movement of water and sediment against the rock causes physical abrasion, gradually breaking it down into smaller pieces. Ultimately, erosion can transform the rock into a smoother, more rounded pebble or deposit it further downstream as sediment.
The steepness of the river's slope, the volume of water flowing in the river, and the type of rock or sediment being eroded are the three main factors that affect how much energy a river has to cause weathering, erosion, and deposition. The faster the flow, the more erosive the river can be.
Erosion could wear down the rock's surface, causing it to become smoother and potentially reducing its size. Deposition could lead to sediment accumulating around the rock, potentially burying it partially or fully over time. Overall, the rock may undergo changes in shape, size, and position due to the combined effects of erosion and deposition in the river environment.
A rock that resists weathering and erosion from a river is likely composed of durable rock types like granite or quartzite. These rocks can withstand the abrasive forces of the river's flow, leading to the formation of a hill or outcrop. Over time, the resistance of these rocks to erosion can create prominent features in the landscape, such as waterfalls or ridges.
Yes, erosion affects a river by changing its shape and carrying sediment downstream. The process of erosion can cause the riverbanks to collapse, widen the river channel, and transport particles downstream, impacting the flow of the river and the surrounding landscape.
Rock flour is a product of both weathering and erosion processes. Weathering breaks down rocks into smaller particles, while erosion transports these particles to another location. Rock flour is created when rocks are weathered into very fine particles, which are then transported by erosion processes such as glacial movement or river flow.
River erosion can affect surrounding land by wearing away soil and rock, leading to changes in the landscape. It can also impact habitats and can contribute to sedimentation in rivers and downstream areas. Additionally, river erosion can alter the course of a river and affect human infrastructure such as bridges and buildings near the river.
Water erosion
The steepness of the river's slope, the volume of water flowing in the river, and the type of rock or sediment being eroded are the three main factors that affect how much energy a river has to cause weathering, erosion, and deposition. The faster the flow, the more erosive the river can be.
Erosion by moving water in a river is called fluvial erosion.

yes
A river's velocity is hugely important as erosion on the outside of a meander is solely down to this factor. This is because the river is hurling rocks (abrasion) and air bubbles into the rock face, causing it to break down quickly. The quicker the river, the more abrasion and hydraulic action will cause erosion. This means that the meander moves outwards, and causes further erosion.
It breaks down rock, creating sediment
Human activities influence different factors that affect the rock cycle, for example, soil erosion and weathering. Human activity such as mining affects rocks' weathering, affecting the rock cycle. Other human activities such as farming affect soil erosion, and soil erosion is a factor that affects the rock cycle.
someone picks it up and puts it in a river, then the river turns it into a pebble with erosion.
