Natural wonders show us how the Earth changes over time. This happens because of natural processes like erosion, volcanic eruptions, and shifts in the weather.

Take the Grand Canyon, for example. It has been changing for millions of years as the Colorado River digs deeper into the ground.

Ways the Earth Changes:

1. Geological Changes:

   • Hills can grow into mountains.
   • Lakes can dry up completely.

2. Biological Changes:

   • Ecosystems can grow strong or weaken.
   • This affects the different plants and animals living there.

As these natural wonders change, their names and types can change too. A lake might change into a wetland or even a desert because of changes in climate.

This constant change shows us how beautiful and strong nature can be.
