A glacier melting is actually an example of **Secondary Succession**, not Primary Succession.
### Here's the explanation:
- **Primary Succession** occurs in an area where there was no previous soil or biological community, such as after a volcanic eruption or a lava flow. It starts from bare rock and involves the gradual development of soil and ecosystems over a long time.
- **Secondary Succession**, on the other hand, takes place in environments where a disturbance has cleared out a community but left the soil intact. This can happen after events like wildfires, hurricanes, or the melting of glaciers, where the landscape may be disturbed but the underlying soil remains.
In the case of a glacier melting, the ice retreat exposes underlying soil and rock, allowing for the re-colonization of plant and animal life. Therefore, the presence of soil means it’s a case of secondary succession.
