Invent a process for the formation of ocean basins consistent with catastrophism

Answer and Explanation:

The process of formation of oceanic basins began with the execution of a catastrophe that caused the gradual erosion of the rocks and the relief of a region. This created a series of sediments that spread throughout the region of legend and continues, with the progressive action of wind, rain, rivers, ice, among others.

These sediments are collected in low areas close to oceanic regions and accumulate there for an indefinite period of time, where they overlap for millions of years. Each year, this process reaches deeper and larger areas until it manages to form an oceanic basin.
