Erosion
Erosion
They change by the rough mountain is on a slope and so the v shaped water changes shape!
rivers
Channel section is in shape of english alphabet "C"
The flow of water in a small channel is commonly referred to as "streamflow" or "channel flow." It describes the movement of water within natural or artificial channels, such as rivers, streams, or ditches. Factors like gradient, channel shape, and surrounding vegetation can influence this flow. Understanding streamflow is essential for managing water resources and ecosystems.
Valleys can change over time due to erosion processes like those caused by rivers, glaciers, or wind. These processes can deepen valleys, widen them, or change their shape and size. Human activities such as mining, deforestation, or construction can also alter the landscape and shape of valleys.
I bet it means channel
A gated channel protein can be opened by specific signals or changes in the cell environment, such as binding of a molecule or changes in voltage. This triggers the channel to change its shape, allowing molecules to pass through.
They erode edges!!
The River Severn is the main river that flows into the Bristol Channel.
Deltas of any rivers will alter over time. A channel may silt up and become blocked, so forcing the water to form a new channel elsewhere - a continuous process.
