The melting and subsequent retreat of glaciers is considered an extreme disturbance primarily because of the significant impact they have on the landscape and ecosystems. The best answer to your question would be:
**A) they leave bare rock with no established ecosystem.**
When glaciers retreat, they often expose bare rock, which can disrupt existing ecosystems and create a lengthy process for new ecosystems to develop. This can lead to changes in local biodiversity and soil composition, making it an extreme disturbance in the affected areas. While options B, C, and D describe various impacts, they don't capture the broader ecological implications as well as option A.
