Answer 1

Primary succession is the process that occurs in an area where no soil exists initially, such as on bare rock. This often occurs after events like volcanic eruptions or glacial retreats, where the surface is newly exposed.

Among the provided options, the situation where "sheets of ice that once covered an area melt away, exposing a layer of rock" is the one that most likely leads to primary succession. In this case, the melting ice reveals bare rock, creating a new environment for organisms to colonize, starting the succession process from scratch.
