A place where matter remains for a period of time within a cycle?

• A. Store
• B. Source
• C. Recharge
• D. Sediment

Answer: (A)

In cycles, matter moves through different locations called stores or reservoirs, where it can sit for a period before moving on. A place where matter remains for a while within the cycle is a store. For example, in the water cycle the ocean, soil moisture, and groundwater are stores because water can stay there for varying lengths of time before it flows to another part of the system. The length of time matter stays in a store is the residence time and can range from days to thousands of years depending on the store. A source, by contrast, is where matter enters the cycle, not where it lingers; recharge is the process that adds to a store (like groundwater recharge); sediment is a material that can be part of a cycle but is not the general term for the place where matter rests.
