Depends on the environment and mode of deposition. I think that you're thinking of an alluvial fan.
What else can I help you with?
What is a fan-shaped deposit of rock and soil?
A fan-shaped deposit of rock and soil is called an alluvial fan. It is formed when sediment is carried by flowing water and then deposited on a flat plain, typically found at the base of a mountain or hillslope. Alluvial fans are common in arid and semiarid regions.
Are fan shaped deposits of sediment called floodplains?
No, fan-shaped deposits of sediment are called alluvial fans. Floodplains are flat areas next to rivers that are covered in sediment during floods.
Where is alluvial fan found?
An alluvial fan is a depositional feature which is formed when fast moving water comes out of a canyon, slows, and deposits the sediment it is carrying on a flat plain into a fan shaped structure.
How are alluvial fans and deltas diffrent?
The bold parts are the differences:An alluvial fan is fan-shaped alluvial deposits created when fast flowing rivers slow down. A delta is a triangular area of alluvial deposits where a river divides before entering a large body of water.If you dont understand:An alluvial fan is just alluvial deposits in a fan shape. A delta is alluvian deposits in a triangular shape. Where and how they are created are totally different.Hope this helped (;
A triangular-shaped feature of deposits at the mouths of many rivers?
Delta - a delta is a landform that forms at the mouth of a river, where sediment carried by the river is deposited and accumulates in a triangular or fan-shaped pattern. Deltas are typically rich in nutrients and support diverse ecosystems.
Where is it formed the alluvial fan?
Alluvial fans are typically formed at the base of a mountain or hilly terrain, where a river or stream carrying sediments suddenly slows down and deposits the sediments in a fan-shaped pattern. This process occurs in arid or semi-arid regions with high relief and limited vegetation to anchor the soil.
A fan-shaped formation that develops when a stream deposits its sediment at the base of a steep slope is called?
A fan-shaped formation that develops when a stream deposits its sediment at the base of a steep slope is called an alluvial fan. These features are typically found in arid or semi-arid environments where streams carry a large amount of sediment and quickly lose energy as they reach flat or gently sloping terrain.
Fan shaped deposits of sediment that form on dry land?
These are called alluvial fans. They are typically composed of coarse sediment like sand and gravel, which is carried down mountainsides by fast-flowing streams and rivers and then spread out in a fan-like shape as the water loses energy and deposits the sediment.
What Besides deltas and placer deposits what else is a result of stream deposits?
Besides deltas and placer deposits, stream deposits can also lead to the formation of alluvial fans and floodplains. Alluvial fans occur where a stream flows out of a narrow canyon into a wider area, depositing sediment in a fan-shaped pattern. Floodplains are flat areas adjacent to rivers that become covered with sediment during flood events, enriching the soil for agriculture. These features contribute to the shaping of landscapes and ecosystems.
What is a fan shaped accumulation of soil called?
a delta. it is usually at the mouth of a river. (ex. there is a delta at the end of the nile river.)
Is the fan-shaped pile of broken rock fragments at the base of a steep bedrock slope or cliff?
The fan-shaped pile of broken rock fragments at the base of a steep bedrock slope or cliff is known as a talus slope or talus cone. This debris results from the weathering and erosion of the bedrock above, where gravity causes the rock fragments to accumulate at the base of the slope.
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.
