Question

which of the following defines when new rock is exposed from a geological or natural disturbance, then erosion degrades the rock over a period of time to make mineral soil, allowing new organisms to populate the area?
ecosystem development
primary succession
secondary succession
ecosystem decay

Explanation:

Primary succession occurs in areas where there was no previous soil, such as when new rock is exposed. Erosion breaks down the rock to form soil, enabling new organisms to colonize. Ecosystem development is a broader - term. Secondary succession occurs in areas that already had soil and a previous community. Ecosystem decay is the decline of an ecosystem, not the process described.

Answer:

Primary succession
