A fan-shaped pattern of sediment deposit is typically caused by sediment being transported by a river or stream and then spreading out as the flow slows down at the point where the river meets a larger body of water, such as a lake or ocean. The slowing of the flow causes the sediment to settle and form the fan-shaped deposit.

What is the triangular or fan shaped deposit of sediment that forms where a river empties into an ocean or lake?
silt This trianguar deposit of sediment where a river empties into an ocean is called a delta.
What causes formation of alluvial fan?
Alluvial fans are formed when a fast-flowing stream or river suddenly encounters a flat or gently sloping plain, causing the water to slow down and deposit sediment. This sediment builds up over time, creating a fan-shaped deposit. Factors such as the gradient of the slope, the volume of water, and the size of the sediment particles all play a role in the formation of alluvial fans.
What is a fan-shaped deposit at the mouth of a river?
A fan-shaped deposit at the mouth of a river is known as a delta. Deltas form when a river flows into a larger body of water, like a sea or ocean, and deposits sediment and other material it has carried downstream. Deltas are typically characterized by their flat, triangular shape.
What are the areas of sediment deposit where a rivers mouth reaches flat land at the bottom of a mountain?
The areas of sediment deposit where a river's mouth reaches flat land at the bottom of a mountain are known as alluvial fans. Alluvial fans are cone-shaped landforms that are created by the deposition of sediment carried by rivers as they flow from steep mountain terrain to flatter regions. The sediment is deposited at the base of the mountain due to a decrease in flow velocity as the river enters the flatter area.
What is an aluveal fan?
Alluvial fans usually created as flowing water interact with mountains. It is a triangle-shaped deposit of sand, gravel and smaller pieces of sediment. There is also a type of alluvial fan that can be found underwater which is the subaqueous fan.
What is the triangular or fan shaped deposit of sediment that forms where a river empties into an ocean or lake?
silt This trianguar deposit of sediment where a river empties into an ocean is called a delta.
What is a fan-shaped sediment deposit formed at the mouth of a river called?
DELTA
What term is used for the triangular shaped deposit of sediment found at the mouth of a river?
delta

What is another name for a fan shaped deposit of sediment that form on dry land?
Depends on the environment and mode of deposition. I think that you're thinking of an alluvial fan.
What is a deposit that forms where a river leaves a mountain range called?
A deposit that forms where a river leaves a mountain range is called an alluvial fan. This fan-shaped deposit is created as the river slows down and deposits sediment and debris that it has carried from the mountains.
What is a fan-shaped deposit at the mouth of a river?
A fan-shaped deposit at the mouth of a river is known as a delta. Deltas form when a river flows into a larger body of water, like a sea or ocean, and deposits sediment and other material it has carried downstream. Deltas are typically characterized by their flat, triangular shape.
What is a deposit of soil that collects at the mouth of rivers?
A delta is a deposit of soil that collects at the mouth of rivers. Deltas form when sediment-rich water flows into slower-moving or standing water, causing the sediment to settle and accumulate over time. Deltas are typically shaped like a triangle or fan, with multiple distributaries carrying sediment into the receiving body of water.
What is a structure built up by stream deposits at the foot of a mountain is called?
A structure built up by stream deposits at the foot of a mountain is called an alluvial fan. Alluvial fans form when rivers or streams carrying sediment from the mountains suddenly lose velocity and deposit the sediment in a fan-shaped pattern.
A wide sloping deposit of sediment?
This type of landform is known as an alluvial fan, which forms where a river's velocity decreases as it emerges from a mountainous area onto a flatter plain. The sediment carried by the river is deposited in a fan-shaped pattern due to the reduced energy of the flowing water.
What term is used for the triangular-shaped deposit of sediment sometime found at the mouth of a river?
An alluvial plain, sometimes also referred to as a fluvial plain.
What does delta mean in cordillera?
In the context of a cordillera, delta refers to a triangular deposit of sediment that forms where a river flows into a body of water, such as a lake or the ocean. This sediment accumulates at the mouth of the river, creating a fan-shaped landform that extends into the water.
