in which of the following situations would you expect succession to take the longest?
a volcanic island forms far from any mainland.
sand dunes form a new island within a half mile of a mainland.
a forest fire burns 1,200 acres in texas.
humans log an area and then burn remaining undergrowth.

Explanation:

Succession is the process of ecological change in an area. Primary succession occurs in areas with no soil (like a new volcanic island far from mainland), while secondary succession occurs in areas with existing soil (like after a fire or logging). Primary succession takes longer as soil formation and initial colonization are slow. A volcanic island far from mainland would undergo primary succession. The other options (sand dunes near mainland, forest fire, human - logged area) have some soil or are close to sources of seeds/organisms (for sand dunes near mainland), so they would undergo secondary succession which is faster.

Answer:

A. A volcanic island forms far from any mainland.
