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 a delta?
A delta is a triangular deposit of sediment at the end of a river or stream. It happens when the strong current of the river slows down and deposits the sediments it has been transporting.
What causes a fan shaped pattern of sediment deposit?
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 happens to the speed of a river as it approaches the ocean?
it slows down
Where do rivers deposit their loads of sediment?
Whenever the river slows down it starts to drop sediment. This usually happens when it meets the sea, unless it meanders slowly across a flood plain in its way.
Why does delta often form where a river meets the ocean?
Because water slows down and sediment drops to the bottom
Alluvial Fan what is?
An alluvial fan is a fan-shaped deposit that is created when a fast flowing river slows down. Alluvial fans develop where streams issue from canyons onto adjacent valley floors and deposit sediments derived through the erosion of rocks upstream.
when a river slows down what does it do to the sediment its carrying?
As a river flow slows, the sediment starts to settle out. The water at the river's edge often has the lowest flow or movement so there will be more sedimentation.
What is the heavy material that's deposited when the river currently slows down?
The heavy material deposited when a river slows down is called sediment. This sediment can include sand, silt, and clay particles that settle out of the water and accumulate on the river bed or banks. Over time, this sediment can build up and create features like sandbars or levees along the river.

How does a change?
the river current slows down it drops of rocks and gets some dissolved materal it carries on down the river two a shore
What is the movement of the river slows down as it nears the ocean dropping deposits that form triangle shaped landforms?
This process is known as delta formation. Deltas are formed when a river flows into a body of water, causing the flow to slow down and deposit sediment carried by the river. The sediment is then deposited in a triangular shape, creating a landform known as a delta.
