Distinguish between Alluvial fans and Delta?
A delta forms when a river empties into a larger body of water. An alluvial fan forms on land where a river emerges from a mountainous area and flows out onto a more gently sloping plain.
When a river flows out of a steep narrow valley an alluvial fan forms because?
The river spreads and becomes shallower and the flow velocity decreases meaning that it has less energy and so is unable to transport the larger clasts (pieces of rock) and so these settle out of the fluid to form an alluvial fan.

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 differences between an alluvial fan and a delta?
a delta is when a river empties into a larger body of water (lake, ocean, etc) an alluvial fan is when a river flows from a steep slope onto more gently sloped land, slowing down and spreading out
What are three affect how fast a river flows?
the three factors that affect how fast a river flows is the steep ,width and depth and how it is curved
