I believe that is from BC Science 7 and the answer is a delta.
Alluvial deposits are river/stream deposits, whether they are found at the mouth of the river or anywhere along its length. In some cases, the alluvial deposits at the mouth of a river can form a delta.If this is not what you wanted to know, please rephrase the question. As it stands, this is an incomplete sentence with a question mark at the end of it.
alluvial fan
Alluvial Fan.
An alluvial fan starts at just a build up of sediment at the mouth of a river. As the current moves, more and more sediment is lifted into the stream and carried until it hits a sediment deposit. As the sediment deposit gets bigger, it is exposed to the air and forms a sediment mountain. As the mountain gets bigger it forms an island in the middle of the mouth of a river. This is called an alluvial fan! Hope this was helpful!
