What are examples of slow changes?

Slow change

The changes happening over a long period of time are considered slow changes. Examples: Rusting of iron, fruits ripening and growing of trees.

Which one is an example of slow change?

Formation of rust takes longer time and is not an immediate reaction. Therefore, rusting of iron is an example of slow change where new substance, iron oxide is formed. 2. Another example of slow change is rotation of earth, which causes day to night.
