Concept:Development refers to the overall change in shape, form, structure and function over time.
Explanation:Development is a gradual and sequential process because it follows a predictable order and unfolds step‑by‑step.
New skills build on earlier ones in a systematic way.
For example, in physical development, a child rolls over before crawling, and crawls before walking.
Similarly, cognitive development moves from simple to complex thinking.
This shows that development is not random or discontinuous, but proceeds in an orderly sequence.
