how does a pond form?\na mudflow blocks a river.\nwater collects in a low - lying area.\nhumans use a dam to create a reservoir.\na depression made by an ice sheet fills with water.
Answer
Brief Explanations:
A pond is a small body of still water. It commonly forms when water accumulates in a low - lying area. A mudflow blocking a river usually forms a different type of water body like a temporary lake or swamp. Using a dam to create a reservoir is for a much larger water body. A depression made by an ice sheet filling with water is more characteristic of the formation of some glacial lakes rather than typical ponds.
Answer:
Water collects in a low - lying area.
