Can you think of something that takes a really long time to change, maybe over years?
Many things take a really long time to change.
Mountains take millions of years to form and erode. Rivers change their course over hundreds of years. The formation of fossils takes thousands of years.
Trees like banyan or oak take decades to grow fully. A child's height increases gradually over many years from childhood to adulthood.
Explanation
The chapter discusses how some changes take years to occur. It mentions that students grow taller each year, and natural phenomena like the formation of landforms take much longer. The question encourages students to think about slow, long-term changes in nature and life.
