Gradient affects a stream's erosive energy by determining the speed and steepness of its flow. A steeper gradient results in a faster flow velocity, which increases the stream's erosive power by allowing it to transport more sediment and erode the streambed more efficiently. Conversely, a gentler gradient leads to slower flow and reduced erosive capacity.

What kind of streams form V-shaped valleys?
The streams that form V-shaped valleys are typically fast-flowing streams with significant erosive power, such as those in mountainous or hilly regions. These streams erode downwards over time, carving out a V-shaped valley due to the steep gradient and high energy of the flowing water.
Why can high gradient streams move large sediment particles?
High gradient streams have steeper slopes, which means they have more energy and power to transport larger sediment particles. The fast flowing water in high gradient streams can effectively carry and move these large particles due to the force of the water flow.
What effect does the gradient of a stream have on the amount of energy it has for eroding soil and rock?
A steeper gradient of a stream allows it to flow faster, carrying more energy that can be used to erode soil and rock more efficiently. Slower-moving streams with a gentler gradient have less energy available for erosion.
What effect does the size of the particlesthat make up a stream's load have on its erosive energy?
The size of particles in a stream's load affects its erosive energy. Smaller particles can be carried further and are more effective at eroding the streambed and banks, whereas larger particles tend to settle more quickly and have less erosive power. Consequently, streams with a higher proportion of smaller particles in their load are typically more erosive.
Why large boulders are present in step mountain streams?
Large boulders in steep mountain streams are often the result of erosion and transportation by the powerful force of fast-flowing water. The steep gradient of the stream allows for a high energy flow that can dislodge and move large rocks downstream. These boulders can get trapped or deposited in the streambed due to the turbulent flow dynamics.
How gradient affects a stream erosive energy?
a stream or river that has low gradient has less energy for erosion
What are the features of a river channel that has a steep gradient?
If a river channel has a steep gradient, the river flows faster and has more erosive energy.
What are features of a river channel that has steep gradient?
the river flows faster and has more erosive energy

What is an old river?
An ' Old River' is a river with a low gradient and low erosive energy. Old rivers are characterized by flood plains.

When the discharge of a stream increases what happens to the streams velocity?
When a stream's discharge increases, erosive energy increases.
What are characteristics of old river?
