Which term best fits a gradual build-up over time that results in larger structures?

• A. Accretion
• B. Change in perspective
• C. Daily (Diurnally)
• D. Expansion

Answer: (A)

Gradual buildup by adding material over time is described by accretion. This term captures the idea that small pieces accumulate step by step, piling up to form a larger structure. In astronomy, planets form as dust and gas clump together through gravitational attraction, growing larger through accretion. In geology or coastal processes, layers of sediment can accrete over long periods to build up bigger features. The other options don’t convey that sense of material gathering over time: a change in perspective is about shifts in viewpoint, daily refers to a 24-hour cycle, and expansion describes growth in size but not the specific process of accumulating matter to create something larger.
