How do streams and rivers change the landscape?
They erode the landscaping around them.
How does a streams based level affect how it downcuts it's channel?
Streams can't erode their channels endlessly. there is a lower limit to how deep can a stream erode. Base level is the lowest point to which a stream can erode its channels.
How does gravity relate to a streams to erode and deposit materials?

What does Streams erode their channels by abrasion by dissolving soluble material and by .?
Streams erode their channels primarily through abrasion, the mechanical wearing away of rock and sediment. They also erode through the dissolution of soluble materials in the water, such as limestone. Finally, streams can erode their channels through hydraulic action, which is the force of moving water against the channel banks.
Does heavy rain make streams erode faster?
YES
What are three ways that streams erode their channels?
Stream erode their channels by abrasion, grinding, and by dissolving soluble material.
When do streams erode sediment?
Streams erode sediment primarily during times of high flow or flood events when the velocity and volume of water are increased. The force of the water helps carry and transport sediment downstream, causing erosion along the streambed and banks. Wind and ice can also contribute to sediment erosion in streams.
How does a stream base level affect how it downcuts it channel?
Streams can't erode their channels endlessly. there is a lower limit to how deep can a stream erode. Base level is the lowest point to which a stream can erode its channels.
What is the process by which small streams erode their forward paths through rock is called?
The process by which small streams erode their forward paths through rock is called abrasion. This occurs when sediments carried by the stream rub against the rock, wearing it down over time.
When do steams erode sediments?
Steams erode sediments when they flow with enough force to pick up and carry sediment particles along their path. This erosion is often more pronounced during periods of high flow, like after heavy rain events or during snowmelt, when streams have more energy to transport sediment.
5 features formed by rivers and streams as they erode the land?
alluvial fans, deltas, groundwater erosion, deposition, soil on flood plains
Why is downcutting the major erosional force in mountain streams?
Downcutting is the major erosional force in mountain streams because the steep gradient and high energy of these streams allow them to rapidly erode rock and sediment, carving deep channels into the landscape. Additionally, the force of gravity pulls water downhill, constantly working to cut deeper into the bedrock. This process is further accelerated by the presence of sediment and boulders carried by the fast-moving water, which act like abrasives to erode the streambed.
